3d artist and auto technician

Im an auto technician here in the US (ford and im working on BMW certs next year) i had a few questions, first off though, im a 3d artist and have been modeling since Half-Life modding came big back around 2000, and would love to contribute if you need the extra help. I just picked up the game and i have to say that im incredibly impressed with it, have done an astounding job with the engine build so i hope you take all this as positive criticism if i give any criticism at all
and this probably is not the place to post this, but im sure it can be moved if necessary.
1. Opposing piston engines such as an opposing 4 engine, rotary engines.
2. Torsion bar suspension, twin I-beam suspension, and leaf spring.
3. Cooling systems, oil fluid type, oiling design such as dry sump, side oiler, etc.
Also in order to better design the cosmetics of a car wouldnt it be more beneficial to be able to manipulate points on a car as opposed to just a broad section of it? i think it would allow more flexible design.
