I really like 315's and want to fit them on my car somehow. What I would like to know is how they drive on the street? are they any different than the 275's I am currently running? I heard somewhere else on the forum that they make the car understeer(?) i think in autocross but i assume they would help in drag racing... Do you people with 315's love them and recommend that everyone have them? or was there not that much of a noticable difference? thanks.

 

If you have a 10.5" or wider rim, then I highly recommend them.

Running them on a 9.5" rim is not good for performance or safety.
Good luck!

 

with oversize 9.5s on the front and 10.5" rims on the back, new aftermarket sway bars, koni shocks and lowering springs, the 99Z28 i drove had less understeer then a stock one... but its far from a stock setup.
