Bit of a worry that it still understeers with a lowered front and standard height rear end? Did you cut the springs or replaxce them with proper lowered springs?

If you cut them, you have effectively also increased the spring rate, which can promote understeer, but with the rear sitting higher, it should oversteer......

Either way, out the 32's on the front, the Medium's in the 48's will be lucky to get enough heat in them in a light weight car to work properly.... they really only work well in heavier cars.

Also, 48's fall off their peak performance pretty quickly, where as the 32's seem to work well all the way through the tread depth.
