I made the tragic error of running at Streets Of Willow Springs in SoCal (very tight and twisty) with -1.75 camber at the rear (rear camber IS adjustable - just get a very big hammer
) and only -1 at the front and had a VERY unhappy time. Run with as much negative camber as you can ge at the front (you may eventually want to install camber plates) and as little as you can tolerate at the back. Running with less than -1 at the back can begin to induce oversteer (some like it). I will run something like -2.5 at the front on the track and -1 - -1.25 at the rear.
