Ask Steve at Speed tech to see if he can deliver them for you. His Tire deals can net you rims, tires, and Yok inserts for about $30 US. You could try a number of things with the setup you have. I'm not too sure on your car but I would try to decrease the droop(less droop) on all shocks, which would yeild less weight transfer, less grip. Raise the ride height of the car is another thing I'd try. Or you could use more camber. There is a point on the camber of a tire that would actually start decreasing your traction is too far in the negative direction. You jcould also hieghten the roll center which would change the geometry of the suspension. The easiest thing would be to change the springs, but I wouldn't if your track is bumpy. HOpe this helps and I think what I've said is correct. I've only beeen in this hobby for about a yr though.
