Very happy with the Dinan springs/camber plates. The car corners much flatter with minimal roll. Less dive on hard braking. The ride feels no harsher, just more controlled. I believe the camber plate changes the geometry of the front suspension such that it negates the 1/2 inch drop the dinan springs provide. The rear is definitely lower, the front is not.
The brakes definitely ran cooler with the rotor back plate cut off. The fronts unbolt when the suspension is taken down to put the camber plates in. The rears have to be cut off.
The biggest difference was the hoosiers. Such a difference running track rubber vs the PS2's.
After seeing my car on the black track rims I think I'll need to powder coat my OEM 19's.
