I lowered about 3/4" and settings at 5 at all 4 corners. The ride is softer over many bumps but stiffer and more stable on cornering. No track time yet. I was told by TPC racing owner/racer that these would be more than adequate, with sway bars for the track, so I saved the $$ instead of gonig with Motons etc...Love them so far !

 

Good luck Scott, hope they suit your purpose.

 

They are a great street coil over system that can hold up to occasional track use.
