For sale here is chassis plans to build Aventador chassis from steel tubes and sheets (unlike carbon-fiber moncoque as in the genuine car). The expected weight of the whole chassis is around 320 kg / 706 lbs, which I calculated with wall thickness of 2.54 mm / 0.1" for most tubes in mind. When using Metric standard tubes with wall thickness of exactly 2 mm, the weight is approximatelly 50 kg less. The chassis is designed in a way that it's still very strong even if tubes with lesser wall thickness of about 1.5-2 mm are used instead, though I recommend higher value for maximum protection in case of accident.
Due to the different tube standards in those continents, there are two chassis designs and two types of plans - for using Imperial size tubes (inches) or Metric size tubes (millimeters). For short I call them US chassis and EU chassis. There are some subtle differences between both chassis. For example, where the US chassis is using tube 1.5 x 1.5" and wall thickness of 0.1" (38.1 x 38.1 x 2.54 mm) the EU chassis is using tube 40 x 40 x 2 mm.
The plans are still in the making (about 30% ready so far), so there are two different prices depending on when the set is purchased. Pre-ordered plans will include bonus set of my Aventador body plug plans

Pre-order price as of May 2013 is 370 USD or 280 EUR (26% off). Once I'm ready to deliver, the plans will sell for 500 USD or 470 EUR. <<<
Recently I changed the way I draw the tube plans in order to include more information (like angle dimensions and where each tube is located on the chassis) and make them even easier to read than before. I had to scrap all plans so far and replace them with new ones. Now the plans are one tube per page, with the aspect ratio being resized to A4 paper format optimized for printing. There is also little change in the tube naming to suit two purposes - 1/ predicting the tube location by its name (I divided the chassis in several portions with unique letter for each) and 2/ to avoid unnecessarily large numbers like "Part 1287" or so. Chassis sections are named with a letter according to their location:
A - floor level (first level of the chassis is
A like the first letter in the alphabet)
B - both
Bumbers
C - engine
Cradle
D -
Door frames
E -
Engine bay
F -
Front end
R -
Roof
S - both
Sides of the cockpit
T - central
Tunnel
W - fire
Wall
M -
Metal plates and sheet

This way, builders will be able to easily fit the tubes at their proper position:

Originally I used a relatively accurate game 3D Mesh model to extract the intersections. However, I make hand drawn curve approximation to replace the straight mesh lines with smooth NURBS curves. I also created 3d solid NURBS models for the Aventador glasses with constant radius to make sure the roof pillars and door panels of the plug will be built properly. Now the cross-sections are modified to follow the correct shape of the glasses. Body kits made out of plugs primarily built without proper glass shape (like all 3d Mesh models from the web) will cause problems and will require modifications to fit the glasses. The 3d solid NURBS models can be used by glass companies to make custom glasses for the body plug and kit. They are NOT 100% accurate replacements of the OEM glasses. However, they will fit my body plug plans.
