has anyone got this spring installed w/ the koni shocks?? They offer a bigger drop thanthe prokit but they are cheaper! Is it because the ride would be more stiff w/ these springs even w/ the koni shocks? Or are the sportlines of lesser quality?

 

they're cheaper b/c they're not a progressive spring rate spring.

 

Yes, they are.

 

ooooo. i stand corrected.

i always thought that they were not progressive. oh well. my bad.

 

I think its b/c they're less in demand. Not many people want to drop their car that much, and if they didn't they would probably go w/ a full coilover system from the start. Check the spring rates on each, but I'd guess w/ koni yellows they could feel the same as the pro kit.
