Replaced my worn out eibach springs with these and the ride is amazing now, paired them up with 350mm rear on stock 17’s and have more than enough clearance yet a nice low ride.

Used these to replace the sagging springs that plaque the GTO. Installed these with all new font suspension (Koni adjustable strus and New bushings everywhere.) These didn't make too much of a difference with ride height because I also replaced the collapsed rubber strut mount. But overall, the ride quality is tons better.
Also, working with Andy has been a dream. Very knowledgeable and quick to respond to messages.
