I haven't driven my car since putting the UPR 12-250 coilover setup in front, but I ran they're coil springs front and rear with the rear pro LCA and UCA (adjustable) and it has done everything I wanted it to. If you aren't seriously pushing the limits, I think you can away with a good spring/shock combo and a nice LCA/UCA. IMO coilovers are a pain for the rear compared to the ease of doing coilovers on front.
