Yes, I have them on my fast and furious car...WOOHOO! Never used them yet though. The quality of product is AAA+++. They seem to be very stiff but mine are not broke in yet. Ride height is very low. If you have a body kit these might create a problem. Right now with my blitz bumper I have about 1.5" clearance with this suspension. I'm having a 1" billet spacer made and adding longer studs to my shock perch to gain a extra inch of height. These coilovers are ride height adjustable/ as well as dampening but are extremely low at highest point.
