As far as traction and stability, most of the action will happen in the rear. BMR is good stuff, I don't care what the price tag says! That shit performs. Track proof just doesn't lie. If you're looking for a mean street car and aren't as concerned about track performance, just about anything that could be considered a budget build will work, tailor it to comfort and appearance. There aren't many part manufacturers that can account for the various grades and quality of street conditions their products will be used on to say "this is a street specific kit." Just consider what it is to drive wreckless on the streets, and what you can do to avoid mishaps. A super stiff suspension isn't going to do you any justice on the street as far as forward traction and stopping traction go. Stiffer typically corners better. Weight transfer needs to happen in order for forward traction and stopping traction to be effective. Upgrade your front brakes, GT500 or at least high quality friction materials. Stopping is going to be the #1 upgrade to support more power.
In regards to FRPP equipment, it should serve well for a mean street machine. I ran Koni Orange/FRPP "K" springs. I loved the appearance and ride quality. Cornered very well (stock sway bars). Stopped really well after the 14" Brembo (GT500) upgrade. No more pedal fade under heavy braking, and no more baked rotors with saucy pads. The J&M LCA & CHE Adjustable UCA with whiteline panhard/support combo kept the rear from sliding all over. It was a very predictable setup, and kept the car looking sharp too. I'd never would've been competitive at the track with that mash-up, but it worked well together on the street and didn't break the bank. I felt completely comfortable at high speed or max deceleration. Slide a few corners with confidence and control.
The beauty of a street car, it doesn't have to be set up to win races, just get the job done.
