Hi everyone I am looking for a monocoque for the Aventador coupe, I am ok with a damaged monocoque also. Let me know if you have anything. I no one has one I would be looking for one or two people that would be interested in going in with me to purchase a used OE monocoque. I have found a used monocoque in the range of $30000.00. Let me know if there’s any real interest. Thanks

Wouldn't your budget end up more costly than an OEM Aventador on the used exotic car market? Have you decided how you are going to license this vehicle after repairing a monocoque chassis designed out of 98% carbon fiber? How soon would my investment of $50K return $100K to my bank? Once drivable, wouldn't the car be 15 years old or more? Sell your used parts and purchase the Chupacabra from 76mx and have more fun sooner.

Thanks 01, Wayne if you do not need to have the original monocoque, my aluminum composite monocoque chassis is available in a 104" (Aventador) wheelbase. This is the same style that I use as a 98.5" Countach and Chupacabra Chassis. $7,000USD for a bare chassis, $9,000USD with the four corners hung. If you happen to be at the NSRA Street Rod Nationals in Louisville, Kentucky on August 2-5, both sizes will be on display in the Steel-It booth at the Trade Show.

Thanks for the reply but I would like to build my replica as close as I can make it so that’s why I am looking for the monocoque. I do have some other parts that I have accumulated and I have been able to score some pretty good prices on what I have already bought so that’s why I am looking for the real monocoque. I have soured a monocoque and am looking for someone else that is looking to do the same thing I am. Thanks
-
I guess that I am missing something. If you do find someone to buy the monocoque with you, do they keep it on the even days and you on the odd ones?
-
In return I could build a replica out of fiberglass for them. I would arrange the pickup and also pay for the shipping so for their part of the payment they would receive an exact copy of the monocoque made from fiberglass. The replica would have to have some kind of frame built buy someone but all the mounting locations and screw holes etc would be there if they would choose to mount factory parts with little fabrication required for mounting factory parts.
-
Thanks Wayne, I understand that part now but am still confused. Five seconds on Grabcad found a free Cad model of an Aventador chassis. Why not use that to cut a plug (or even cut a negative and go straight to cutting the mold and eliminate the plug step entirely) instead of purchasing a thirty thousand dollar plus monocoque to do the same thing? Especially one that has to be repaired first.
-
76mx I have looked at some of them on Grabcad but I’m not sure if the models they have would be to the correct dimensions plus I like the idea of being able to pull a mold where I can get all of the bolt holes for everything that bolts to the monocoque so that’s why I am wanting to find one. If it’s damaged then I most likely will just use it to make molds so as long as at least half of it is in good enough shape that would work for me. I know I’m hard headed but I really like the idea of being able to make it as close to OE as possible. I would even pay for a 3d model from an OE monocoque if I could find one. I have tried to find a company or individual that could make a negative mold but when I have talked to company’s about it they tell me it would cost more for them to do than buying a used monocoque. If you would happen to know of anyone that can help me get what I’m looking for for less than what I have found then I would be great full for the help.

Wayne: After you purchase and repair this (?) monocoque when you find one after you find investors willing to "give" you their hard earned money and you somehow get someone to make some molds of "all" of the panels that are required for this Aventador (plus all of the thousands of other parts required), there will be a "knock, knock" at your front door. You will be greeted by two lawyers from the AUDI AG corporation, EU. They will explain the "NO, NO" of what you have worked so hard to accomplish. They frown on people reproducing exact replacement parts for monetary gain as with your deal with your "investors".

Wayne, there is still a lot I do not understand about your project but here are some things I am pretty sure of. 01 is right about the legality. Build all you want for yourself, but when you sell them it crosses the line. Finding investors for a business plan that is not legal might be tough, but I do not think you will need to worry about that, I think the market for people wanting a fiberglass replica monocoque tub to bolt real clips onto is absolutely zero. I do not think you could copy the tub in fiberglass and have it strong enough to work like the composite tub without massive modifications, which kind of defeats the whole original idea. Having said all of that, there is still a much easier way to accomplish this. Tell the chassis that you have found that you are not interested in buying it, but would pay $1,000 for someone to look at it for an afternoon. Contact their local white light 3D scan service (yes not only do they exist, they are plentiful) and have it scanned, should be about $2,000. Spend another $1,000 to clean up the scan and prep it for plug cutting. Spend $2,000 to cut the plug. $6,000 max and you are at the same point without investors and without well over $30,000 spent. Before you do it either way, I would first spend some money on some engineering and see if a fiberglass tub is strong enough to support a car, let alone strong enough to replace a composite tub using only it's dimensions. I just do not think so, fiberglass is not much of a structural element, and selling tubs that break in half is not much of a business plan.
-
I can guarantee that FG will not be strong enough, especially if you intend to occupy the same envelope. Even carbon fiber must be oriented correctly, have the properly balanced resin to cloth, and lets not forget the autoclave. I am not questioning your financial resources, but if I were to ever consider that kind of expense it would be on a uniquely designed auto
-
76mx thanks for trying to help me find a solution but I’m already a step ahead of you. I have offered cash to hire someone to take a 3d scan of it and they would not allow me to. I even asked if I could take a walk around video of it and they would not allow it. I even took it one step farther and asked if I could take pictures of it to have stitched together and I got the same answer that they would not allow it. I did offer money to do each of the above so I am still looking for other options.
Adrian Burton I am not disputing that fg will not be strong enough by itself as I realize there will have to be some kind of frame built but I figured I could take things one step at a time as I know it’s going to be a huge step just to find a monocoque that either someone will allow me to make molds of or one that i can buy. I figured that getting one that’s damaged but at least half of it is in good condition so I can make some molds would be the first step.
-
I offer no expertise here at all, but allow me to chime in just for a moment. AB, it doesn’t seem that he answered your question. Or am I mistaken?
-
Minihawn I did reply to Adrian in the same post just farther down on the post.
-
I know that structural composite layup is a very exacting science, and the skill required to do it correctly is a rarity and therefore EXPENSIVE. I do understand the thought process though. But the high cost of the autoclave access.... it is painfully expensive. Either way, keep us posted. I would like to point you in the direction of 76mx, he has worked out a phenomenal chassis that has a TON of flexibility built into it that will allow you to get a million miles down the road and save a TON of budget
-
Wayne you said it incorrectly...you are not "Hard Headed" you cross that line already. You remain me flat earthers.
You know how much expertise and wisdom this guys have? you are ignoring there advice. That chupacabra chassis is light, strong and affordable. If the chupacabra chassis were available when I started mine, for sure I'll ordered one from 76
Why insisting on doing a replica with a monocoque out of fiberglass that is not safe. Do you have an idea how much completing a replica will cost....I guess you don't.
My friend if you have $30k to spend on a damage monocoque and you are willing to pay big bucks to repair and do molds and all that sort of things....why you don't buy a used Avantador.
Did you check the grab cab file?, how you now is incorrect, if is incorrect, did you know can be scale it to be accurate.
...And remember at the end of the day the monocoque won't be seen by anybody.
-
Ardillo thanks for your input but I am sure that 76mx and many others started out somewhere and they didn’t just have their vision and thoughts complete without a lot of trial and error. I am sure 76mx chassis is an excellent choice as I have only heard great things about it but I am just trying to do something different as I have a vision of what I would like to accomplish.
-
Wayne, best of luck with your project and I am envious of your financial clout. There is one more thing that I do not understand. What are you going to do for a body? I have been to Carlos' shop in Mexico and also went this last March to Rhode Island to see Carl at Duraflex. Those are the only two Aventador bodies available that I am aware of, and neither one is exactly accurate in wheelbase and dimension. My trips were to verify the tweaks needed to make my chassis fit them correctly, and I now have a chassis version that does. Your exact replica $30,000+ monocoque will not fit them. Are you going to spend another fortune to replicate the body?
-
Ok stay tuned because I am working with a reputable company that is probably going to make a monocoque for me out of foam that will be a starting point for me. I will be making payments so it will be a while before I actually get the monocoque made out of foam. I will still have to build a frame into the monocoque but that will come after I get the foam monocoque so stay tuned for more.
-
alright!!! can't wait to see it

Wasn't that the monocoque that Lamborghini had problems with being too flexible and had to be strengthened with steel?

-
I’m not sure, never heard about anything like that but it would be nice to know if they did have problems and if they did have to add additional support.
-
Nope! I couldn't find it either. Lots of "Old" chatter about the monocoque but dated to 2013. Special layered resin saturated pieces cooked in an oven over the molds type of process. I always hear that it's lighter and stronger than steel then I watch a F1 smack into a barrier and burst into a thousand pieces and the driver is pulled out with two multi-fractured legs. If you are going to make your own, better take a flashlight as I don't see any light at the end of the tunnel. Make sure that you vacuum bag your pieces but will that even be enough?

Greetings to everyone. I finally found a damaged monocoque that I am buying but it’s gonna be 2 or 3 months before I have it paid off and then my build will begin. If anyone has a copy of an OE roof for a coupe please get in contact with me as that’s the part I need to source. Thanks
-
Got the monocoque paid off now I’m waiting for them to ship it to me, still looking for a roof if anyone has one? Thanks
-
I don’t jump on the boards my anymore but saw this post and figured I’d chime in as I’ve restored 2 aventadors from the ground up and working on a third. Someone on this chat suggested it would be cheaper for you to buy one at auction and I have to agree with him. Unless you have the front frame, and rear frame and at that point you would be keeping at the very least both push-rod suspension setups and basically doing an engine swap to an LS or something like that, the monocoque isn’t going to be much help. No one is going to replicate the monocoque in the exact fashion lambo built it. I don’t care what size their clave is, they would basically have to cut up the monocoque to figure out how they formed the structural aluminum woven into it (the monocoque is not all carbon). Second, after the 30k spend (you won’t find one state side that has a salvage title for that, you would be more like 60–70k) what exactly would be the benefit of having it? Aside from the roofline. I apologize in advance if I’ve missed the meaning as to what you would actually do with the monocoque but the amount of money you would be spending to basically have something that is going to be of no use to you, I would grab one of auction for 125-150k and make that the project. But in the long run financially speaking, that is going to cost you 125k ontop of that just to get it going, where as I would just sit and wait and snatch a slightly higher mileage one up for 225k range.
-
Thanks for your reply. I have the front and rear frame and a bunch of other parts for my build and have way less than $30k invested so far. I have not found any Aventadors that have been damaged for sale for under $125k so I think I’m gonna keep on going with my build and besides that my wife would never be on board buying one for $125k plus so the only way I’m gonna get on is buying individual parts and build my own. Thanks
-
Gotcha. Well if your ever looking to sell anything that you might splash or dup hit me up. I always buy anything aventador. Vice versa if you need anything let me know. I have multiples of every single aventador part for both coupe and roadster including multiple monocoques. I have a monocoque for sale for 55K with salvage. I'll include dashboard frame with it. My advice to you would be to ditch the rear and front frames if your not going with the original push-rod suspension setup. First off the rear frame is garbage. You could build something much stronger for your application. Second, you could literally dup the front and rear and grab all the mount points necessary and sell the 2 frames and have 10-15k extra. Unless your trying to register this thing as an aventador, you would be much better off recreating the cockpit in steel or aluminum. just my 2 cents, but i can assure you that if you think your going to grab a monocoque and slowly build this thing using all original, your going to be at another 100k-125k easy. If you have original front and rear frame, I have every single frame bracket for both front and rear if interested. One other option for you would be to use a murci chassis and rework it to go with the panels. Heres some pics of just some of the stuff I have for the aventador. I also have 2 sets of COMPLETE SV interior for a coupe, brand new as well as a complete S exterior. Good luck with build

Your link doesn't work...
For my build I am using as many OEM body panels as possible except I am using a custom tube chassis. Anyway, I was wondering if you have oem or fiberglass copies of the little panels that sit in front of the moveable air assemblies. These are the little body panels that transition from the movable air assy to the roof. I would also be looking for the trim pieces that go around the window on the coupe. actually, I could use a lot of OEM parts but my non existing budget stops me from going to crazy...

I am making slow progress on my Aventador kit. What do you guys think about my roof?
-
The roof looks great, Wayne! What are you working on next?
-
Thanks Neils88. Next I will be trying to get a damaged monocoque that I found that needs a roof and will be installing this roof on and installing aluminum or steel to reinforce it.
-
Just met Charlie Strickland yesterday and had a chance to look at a chassis he is selling and man it was a nice chassis. Wish I wasn’t in so deep on my current project. Charlie is a stand up guy that is going to be helping me on my current build. If there’s interest I may post some pictures. Thanks

I would like to hear about these foam pieces and what not. I am interested in building a concept car inspired by the Lambo Aventador. Really be sweet to have dimensions so I could draw it up on inventor or solid works. I have found a company that builds carbon fiber parts etc. with drawings. Bu I need to make the drawings and my labor might be cheaper. I need to custom design a mold for the monocoque body and top. I plan to make it an EV. What's the word on the street?
-
Hi everyone. It has been some time since I posted here about the monocoque. I have started to repair the monocoque. If you’re interested and want to follow along please visit my channel. Lamborghini Aventador monocoque

I would estimate that you will spend more money in parts/trans/engine/wheels/suspension/etc than the price of a used Aventador after 15 years of pulling your hair out.
HOWEVER, Kindig took a 3D image picture of the rear of a car, added a cad file of a rear spoiler, and 3D printed the spoiler in 3 pieces which were designed to interlock with each other. The end result was a perfectly made part that was used to make a mold off of. Any 3D image can be mirrored to make the matching part for the opposite side of the vehicle.
Depending on which state you live in, there are numerous hurdles that you will have to jump through to get your car licensed and registered and may not be feesible at all. $0.02

Thanks for your reply. I am going to use a C8 Corvette drive train on my replica. I am not trying to license the monocoque I’m working on, instead I’m going to make an aluminum frame. Going to use the monocoque to make molds to incorporate with the aluminum frame. I’m aware of the hurdles in order to license and register the car afterwards. I already have numerous parts that I’ve been collecting for around 4 years now and have made numerous parts Stay tuned for progress this year.

Trying to remember how to post pictures here, it’s been a while. Thanks

I’m making progress on the monocoque. What has been done on it is strictly only to pull a molds and then will be removed and new carbon fiber parts will be installed. The passenger side of the monocoque was halfway gone including the complete roof and firewall when I started so I feel like I’m making good progress.
-
Looks great Wayne! Really coming together!
-
Hello everyone my plans have changed and I have to sell all of my Aventador parts. I will be selling for much less than I paid to move them. Please let me know if you are looking for any parts as I have many. Thanks
