I had to use dual shock absorbers because turned out single shock absorber would not hold weight of the completed model. Using second absorber this way allowed me to avoid redesign of the front suspension. =)
Some parts of model are flexible, like bumpers and front part of the roof. In the same time the base of the model (stuff that in between front and rear axles) is rigid, since i used technic bricks instead of beams.
I was able to put turbo under the hood, as well as intercooler inside front bumper. But i failed to build full intake manifold and exaust. =(

maybe you can add second bevel gear with pinhole on the axle. It will rotate in opposite direction, thus canceling movement of first one. I have no idea if it gonna actually work. =)
