I will never understand why some people act like coil overs are the only way. If you have good quality shocks, a lowering spring that doesn't drop you to low is perfect for most people on the street. Coil overs are more expensive, typically a PITA to setup, usually low quality unless you spend...
Just a head up from my own experience, if you run this exhaust I wouldn't recommend full downpipes as it is ridiculously/ unbearably loud. I ended up contacting Stillen and buying the muffler sections. I prefer my cars to be on the loud side but this was a shock to the senses, and not in a good way!
