Aventador custom chassis drawings for 500 USD / 470 EUR

[plans4sale]

UPDATE:

- I'm close to complete this project, having most of the chassis plans nearly finished, and remaining ones require minor fixes and details to be added. Areas to be finished are for the rear suspension, rear bumper frame, sheet metal, some metal plates, door frame and door hinge. Once I'm ready with these, printing of the final chassis plans and composing a tutorial DVD will start in January 2014. Still looking for the best option for good quality and price ratio.

- The current lower pre-order price (450 US Dollars or 340 Euros) has expiration date on 31th December 2014. Starting the regular price (500 US Dollars or 380 Euros) from 1st January 2015.

- Front area next to the suspension A-arms is reinforced with 4 extra tubes to provide better small overlap frontal impact resistance. This addition vastly improves the safety when the car is being hit at either side.

- A new way to create the A2-pillar* framing, in order to allow better visibility and customized shape depending on your body kit. *(the pillar that's located between the front quarter window and the door window of Lamborghini Aventador or Finnluxury Tritium)

- I re-designed the engine cradle mounting points and increased the total number from 6 to 8. Now they consist of 45-degree cone-shaped metal inserts. Originally, I was using laser cut metal plates as mounting points, but the newer design have the following advantages:
1) It allows self-centering of the mounting points to the correct position as the engine cradle is being raised towards the chassis.
2) It provides increased larger contact area, hence less pressure taken by the mounting points (and lower chance to damage the paint in between).
3) It unloads at least 90-95% of the stress usually transferred to the mounting bolts.
4) There is no more chance for sideways bending compared to metal plate version, because the mounting points are now solid cones and integrated in the tubes.
5) It has a better rust protection, thanks to the raised cones and closed cap design.
6) If looks more discreet.

 Hi Rob, this car project is called Finnluxury Tritium aka FLT. I did the design of it and the CNC-milled plugs are currently under development by a member of this forum known as Tantukka. He could provide you with more information about the kit, schedule, pricing, etc. The body kit is designed to fit my Govedo chassis from this particular topic, though that will require dedicated mounting points to be added to it in order to attach the body panels. You can also check its FB page https://www.facebook.com/finnluxury and this topic on MM: http://www.madmechanics.com/forum/general-kitcar-chat/18904-flt-supercar.html
 

[Rob James]

May I ask if the Pink Limbo on your Facebook is something you've built? Can I ask if you have the plans for that particular Kit, or can you tell me where to source the Kit? Or if you know the particular model of Aventador?

 UPDATE:

 There is a new time-limited offer for my Govedo chassis plans, which is a lower pre-order price for students only, set at 400 US Dollars or 300 Euros. Pre-order price for non-students remains the same at 450 US Dollars or 340 Euros. *Final price (after expiration of the pre-order period) will be 500 US Dollars or 380 Euros.

 Bottom of the engine cradle was fully redesigned, to help improve the performance of the rear suspension and add stiffness to the engine bay structure.

 Customers of the EU version of the chassis plans will receive a major update with over 30 new plans tomorrow. US customers already got this update previously, but now is time to make up on the EU side.

 UPDATE:

- The chassis now features dozen newly added reinforcements in key areas, mainly to help the passive frontal crash protection, especially important in the case of an overlap crash when the car's front is being hit only at one side. Those with previously started chassis builds will not need to modify any tubes already welded, because the main chassis design remains the same. The new reinforcement tubes and laser cut plates are additions, hence they will be welded to the existing structure subsequently.

- Reposition of the front lower control arm mounting plates, for easier access to the bolts.

- New way for attaching the engine cradle to the chassis, now fully eliminating any loose movement of the mounting bolts.

- New set of plans will be sent today to customers, with much more to come in next days.

 Hi, there may be more people building chassis privately, but so far I'm aware of two open build threads. You can see them here http://www.madmechanics.com/forum/build-diaries/17361-aventador-chassis.html and here http://www.madmechanics.com/forum/build-diaries/18902-venta-r-build.html respectively. The first chassis is EU version with tube sizes in millimetres, and the second one is US version with tube sizes in inches. Over the next few days I will be sending a good amount of new plans to my customers, and I will be glad to see some more builds started soon.

[exoticcar]

Do you have anyone who has made a chasis yet with the plans you are selling?  If so I would like to see their progress and their feedback.

[plans4sale]

 From tomorrow I will be sending updates to anyone waiting for the EU tube plans, as well.

[plans4sale]

  I'm glad that you like the plans I sent you so far! I just added a few more that I made today, and next ones are coming tomorrow.

I received the first group of plans late last night and started building my chassis this morning.  Thanks Bobi!  Looking forward to the rest of the plans as you finish them.

The plans themselves are very well done, not only do they have all the basics information you need like material thickness, outside dimensions, lengths, qty, etc but it also shows you where in the chassis these parts go.  This feature really helps understand how that part fits into the overall assembly without having to look at an assembly print... nice addition...

So far the tubes are fitting together perfectly with no issues!   

[plans4sale]

UPDATE:
 
 In next days I will start delivery of the tube plans. I try to make US and EU plans simultaneously, and more detailed, so it's a bit slow. By the way, these are totally new plans, with better anti-aliasing and thicker line types to allow easier to read printing, as well as some new additional information added, such like: wall thickness (I now use .083" for the US version, and 2 mm for the EU version), mentioning the location of each tube on the chassis, accompanied with a tiny diagram on the upper right corner for quick reference. I post an example here.

 UPDATE:

 After all adjustments I made recently on the 3d chassis design, I'm now working again on creation the tube drawings. The final version of my Govedo chassis plans is expected to be ready after about one month from now on. There are people who are waiting since long time ago to start their chassis builds and I would like to say thank you for your kindness and patience. It's so close now! I will do my best to fit inside this time frame and start printing the plans sets and then send them via post in an envelope. Normally, one set of printed chassis plans will cost 500 USD or 380 EUR. However, until then I pre-sell the plans for a discount price of 450 USD or 340 EUR. Shipping is included in the price.

 There are still people asking me if the chassis plans cost 75 USD as the topic's name suggest, but this no longer applies in this case, as that lowered price was only an initial offer I made based on a much simpler chassis design that was supposed to take me a lot less time. The chassis now has more than double number of tubes than the amount originally planned and it comes with door hinge design, as well. I can't change the topic name to have the appropriate amount. I rely on the belief that there must be a total transparency in doing business, thus I purposely leaved intact my original posts in this thread as a back-up for free reading, even though the chassis was significantly changed/improved over the time and pricing has slowly increasing as I was progressing. It should be mentioned that those who pre-ordered at the initial lowered price for the simpler chassis will receive the exact same full packages and customer support like the newer customers, as a regard for the support I needed initially upon starting this project.


 Below is a quick comparison between the Govedo chassis and the NAERC chassis. I measured the difference they both have around the firewall. On my chassis, the firewall has about 100 mm more room in front of the engine at the engine's upper level (meaning my firewall is moved closer towards the seats), and the lower half of my firewall is located another 40 mm more forward (for a total of 140 mm more room than NAERC's firewall). I marked the back side of both firewalls with yellow lines.

Each Govedo chassis and suspension set/license will be shipped in an envelope with paper plans and CD, which consist the following:
 
 - AutoCAD files with 2d drawing of each individual sheet metal piece and metal plate saved separately and ready for laser cutting.
 
 - Printed A4 paper plans for each individual tube and sheet metal piece, complete with dimensions and part number for easier locating in the chassis. Along with the full measurements, unrolled tube end templates will be available for the few tubes that require complex end notching. This way, you could use these templates and hand plasma cutter or even angle grinder, just in case you don't have a tube notcher.
 
 - Lots of JPG or PNG picture drawings of all tubes assembled together, complete with measurements and guide instructions. Basically, these are full views and close-up views of the chassis (or portion of the chassis) from various angles where the individual numbers of each tube is placed to allow proper understanding of the whole assembly.
 
 - 10 views of the chassis placed in a semi-transparent body of the Aventador.
 
 - Drawings of bent round tubes for the roof roll-cage. Keep in mind that these are designed around the 3d model of Aventator which I use as a reference for the chassis design. If you have a kit with too inaccurate proportions/size, then it's possible to require slightly differently shaped tubes on the roof.
 
 - Suspension drawings with custom designed A-arms and front/rear wheel hubs (aka knuckles). The suspension is designed to utilize Corvette C5 hub-bearings, QA1 rod ends, and QA1 coil-overs. Please, let me know in advance what is the wheel offset and width of your rims, so that I can apply changes to the A-arms and chassis according to your measurements.

- Door hinge design, includes AutoCAD drawings and a 3d solid model.

- Various videos of the 3d chassis.

Update:
 
 1. My chassis is now officially called "Govedo chassis". The word "govedo" means "bull" in Bulgarian language, so this pretty much sums it up.
 
 2. I'm almost ready with the front suspension design and this will allow me to continue with the creation of tube chassis drawings. I had to temporarily pause the creation of drawings, as on theory there was a risk of potential collision between the front wheel and the chassis. My recent 3d suspension simulations proved to work just fine with the current chassis design. Because my chassis allows for about 82 mm wider feet space next to the front wheel than NAERC chassis (418 mm versus 336 mm, respectivelly), it was mandatory to ensure that there will be enough free space between the front wheel and the chassis while the former is being turned up to 37 degrees, in order to match the turning radius of the genuine Aventador.

 3. I also did some calculations of material volume used in a slightly modified 3d NAERC chassis (free download here:  ), and it turns out that it has very similar numbers almost matching my own Govedo chassis, despite the more massive look and higher strength of the latter. However, both, the NAERC chassis and Govedo chassis are lacking some sheet metal, so the final numbers will vary a bit. I post some sample comparison below.
 
 NAERC chassis floor, both sides (6.35 mm / 0.25" thick sheet only): Volume = 10,669.0036 (+/- 1e-05) cubic centimeters
 Govedo chassis floor, both sides (4 mm thick sheet over reinforcement tubes): Volume = 9,279.2628 (+/- 0.00053) cubic centimeters
 
 NAERC chassis with firewall and floor sheets, no roll-cage: Volume = 41,889.2824 (+/- 0.0018) cubic centimeters
 Govedo chassis with firewall and floor sheets, full roll-cage: Volume = 41,772.2091 (+/- 0.016) cubic centimeters
 
 
 
 4. Here is the 10-clause policy for using my Govedo chassis plans (the buyer of these is referred as to "builder", and a single full set of my custom chassis drawings is referred as to "chassis plans" for short):
 
 1) Upon buying the Govedo chassis plans, the builder agrees to all the conditions below;
 
 2) The chassis plans set contains a full number of drawings allowing to build an entire custom designed chassis and suspension called "Govedo chassis";
 
 3) The Govedo chassis should fit to any properly built Lamborghini Aventador body kit, as well as to the Finnluxury Tritium kit (aka FLT). You can also develop a custom body kit for the chassis. Worth mentioning is that the FLT kit uses additional custom designed adjustable mounting points to accuratelly fit the body panels in their exact position. These mounting points are not supplied with the chassis plans since they are aimed for use specifically with that particular kit.
 
 4) The chassis plans is a single license and can be used to build one chassis only, be it for personal use or commercial purposes. A single license can not be used to build two chassis or any greater number;
 
 5) A builder who previously purchased the chassis plans can additionally build a second chassis (or any greater number of chassis) by purchasing a  new set of chassis plans/license worth 75% of the price (i.e. 75% of 500 USD or 380 EUR = 375 USD or 285 EUR); Builders who would like to mass-produce my Govedo chassis at numbers greater than 5 (five), should order at least 5 licenses at a time worth 50% of the price (i.e. 5x 75% of 500 USD or 380 EUR = 5x 250 USD or 190 EUR = 1250 USD or 950 EUR);
 
 6) Since there is a risk of an illegal piracy of my chassis plans, which is a non-controllable process and heavily based on consensual obligation and trust, it's assumed that the builder is conscientious, understands the clauses in this policy, and shall respect the vast amount of CAD work done by me and the time spent during that process. The builder is personally responsible to not share, re-sell, give as a gift, scan, upload, modify, reproduce in 3d and share, or any other type of unfavourable action that violates the trust granted via the purchase of the Govedo chassis plans. If you do not understand the clauses or will not respect my work, please, do not order the Govedo chassis plans;
 
 7) The builder can freely modify his/her chassis built after my chassis plans, if he/she considers the need to do so. However, this does not allow him/her to use the modified design based on my chassis plans for commercial or non-commercial purposes for another chassis, i.e. a partially modified chassis design of my chassis plans used to build a second chassis (or any greater number) will violate clauses #5 and #6;
 
8 ) The Govedo chassis is primarily designed for personal usage by the builder in the form of chassis drawings, build diagrams and text instructions, thus the final build quality, symmetry and safety of the home built chassis heavily depends on the work done by the builder, as well as the custom and/or donor car parts used in the built. I put my whole expertise and effort into designing this chassis, and I can say for  sure that it features above the average safety/strength level usually seen in  the component- and kit car field. However, any mechanical issues, cracks in the welds or tubes, rust, improper cuts and assembly, improper size and/or type of tubes, potential injures or any other accidents caused while driving a car based on the Govedo chassis are by no means related to me. The full responsibility on how my chassis plans set is being used to materialize the actual chassis lies on the builder. If you are unsure whether you have the skills, knowledge and equipment to handle the work necessary to build the chassis and suspension, please, do not start this build at all, or try to find a reputable builder to properly do the job for you. If you are going to often drive the car with speeds above average (like on highway or track racing), it's highly recommended to use additional safety features, such like: racing roll-cage, stronger brakes, suspension parts, 4-point racing seat belts, etc.;
 
 9) You can contact me personally for any additional information and help during your build of the Govedo chassis. It's my duty and pleasure to try to respond as fast as I can whenever I'm at home.
 
 10) If you enjoy your build and eventual ride with the car based on the Govedo chassis, please, share your thoughts and feelings.

 As the wheel turns left or right, its upper two pivots go forward or backwards, thus adjusting the camber and caster angle depending on the turn degree and direction. The light gray lines next to the upper linkages show the maximum path of these while the wheel is turned left and right, respectively. I spent whole day and night in testing that suspension setup and made multiple improvements during the process. While turned by 35 degrees (usually only during parking), the wheel can go up by 50 mm or down by 35 mm without a collision between the rim's inner lip with either of the upper control arms. Obviously, in real life you can never have situation where you, both, have the wheels turned to the limit and pushing the front suspension so hard that it either goes 50 mm up or 35 mm down simultaneously. Such massive forces usually are present only during high-speed cornering when the wheels are rarely turned sideways by more than 10-15 degrees. But I did that 35-degree test to simply reassure that my suspension setup will be working fine even at these extreme conditions.

O.K. ...I looked at your front a-arm image and I guess I am missing something here. Can your car not turn left or right?
