Question
 

If i go get a NSX body will it fit on the 350Z chassie?

No, the NSX uses a medium chassis wheelbase.

It can fit, if you change the driveshaft out.

you know what bodies would fit on a 350Z?


RSX?
Supra?
Civic?

also....this is kinda off topic....but what do the foam tires do?....are they just gripping tires?

Any body will fit any chassis. You just have to change the front tab, and if necesary, change the center shaft. BTW, this has been covered many, many times before. Please search.

foam tires
 

foam tires are for racing on carpet like racing surfaces like the RCP-tracks are not smooth and hard they are rough and soft foam on carpet gives extreme traction on a smooth surface it will just spin

Foams bite the corners great.
But don't bother with the XMod foams.
Too narrow and the wheel diameter is a bit small.
