    Okay, lately i've seen pictures of the foose coupe. What the hell is the reason for the indy style/F1 style wishbones? As opposed to regular hotrod wishbone or a-arms? Anf what are they made of?

    Secondly, i've been reading chassis engineering by Herb Adams. He talks about the degree angle of the shock/spring. He goes on about 90', 45', 70' etc. From this he says that at 90' (think horizontal, making a perpendicular angle when possible with the degree of the spring.) the spring is 100% effective, whil at 45 or 70 it is less effective. How is this possibly beneficial to the way a formula car is setup? Meaning how the springs are attached to the chassis and the connecting rod.

    If i wrote this in a confusing manner i apologize, and will try to simplifly it a bit.

    Do you actually think that **** is for performance? Betcha Foose couldn't build a race car to save his life. He just building crap for the street.

    No, i knew it was for looks. However, the fact that he used a performance racing suspension on a road car, made me think of whether it was pliable on a street application or not. hence my previous questions.

    Pliable? OK...

    Ride and handling are affected by a number of factors. I suspect you're thinking about ride quality. For that, much is dependent upon spring and damping rates. It matters little whether you've got a coil-over-damper or pushrod set up--an decent engineer can do whatever you like.

    What Foose used is not quite a "performance racing suspension". Road car suspensions are typically configured for cost and packaging factors, hence why you don't see "racing car" suspensions on production cars.

    You might want to pick up some race car engineering texts.

    Well, anyways, can you answer my second question then. It seems as though you know more then i do, and it is more relevent to the foose car.
