I need your opinion on which GC bump stops to get. They have two different kinds
a soft progressive one and a firm one. Which would you choose?

Get the Koni bumpstops.

I know they are the best but I think $80 is a bit much. I have seen them in group buys for much cheaper but not recently.

I would call GC and tell them what your suspension setup is like and let them recomend which ones to buy just like I did when I ordered mine recently.

It's all about how you want your suspension to feel when it bottoms out. if you get the firm ones you will definitely feel when your car bottoms out. The progressive ones are a little more forgiving when the suspension bottoms out. Just my .02

u get what u pay for..u dont want them too soft and u dont want them too ahrd either..what are using,springs and shocks or coilovers.

Konis on all 4 corners with Ground control coilovers 8" 300# front 7" 250# rear.

ooo ok..get the konis...cant remeber if i stil have my stock ones..i have tein super streets so i dont know if the got replaced or not..i forgot..go with a soft ride but not too soft so it bouches and not too stiff to were u feel everything..
