Been doing a lot of reading about springs. Just thought I'd ask what people thought was the best spring for ride quality. I'm not worried about handling and taking 90 degree turns at 60mph. I don't drive it like that, and I don't autoX it. I'm thinking either Eibach Prokit or KG/MM SuperSport at the moment. I have 18" wheels. Thoughts?

Also, does lowering void any warranty? And are the KG/MM SuperSport springs progressive rate?

Thanks!

 

eibachs should do the trick... about 1" drop with similar to stock ride.
i assume that your wheels are not rubbing now and that you have correct offsets, etc.

 

I've got the KG/MM racing springs which are ~1.5". The supersports should drop you ~0.6"-0.7". Good luck.
