For those with GC coilovers, do you regret getting them? Is it that much better than stock? Im seriously thinking about purchasing them. Let's say i do not track the car, would i notice a difference to the point where im going to have a smile on my face when i take corners ?

It depends... each GC suspension is built to your needs. When you call them, tell them exactly what you are going to do with the car and they will send your the right spring rates for your needs. Some people are running as low as 350-400# spring rates while others are upwards of 800# (those are the race cars).

Personally I'm running 500 (f) and 600 (r) # springs. It makes the car more go-kart like.
