Rewrote on 8/26/21——First off, the pillowballs in the top hats of the coil overs came very siezed and would cause the springs to bind so badly that the car was undrivable. The wheel would not come back, and the car tried to pull me off the road whichever way I last turned, after hours of working them back and fourth with penetrating lubricant and grease, and after trying negative and positive preload on the spring, the binding issue is still very prominent. Second, the spring will NOT stay on the lower perch. It gets cock-eyed and twisted and makes a ton of noise as well as changes the feel of the steering. Lastly, where the shock body threads into the lower mount, there is a ton of play that is audible and visible in the video I will attach. It’s enough play that it clunks and pops very aggressively and constantly while driving. The lock nut that holds the shock body tight from spinning against the lower mount will not stay tight because of the play. I put these on my drift car in April and have at most drove the car 700 miles. These coil overs affect my steering so poorly I’m forced to buy a different brand and my multiple attempts to reach someone to have these replaced, fixed or even refunded have failed. They told me I could purchase new pillowballs off their website instead of warrantying the brand new part, and they pass me all around having me fill out different forms and warranty requests and I haven’t heard anything back that’s helpful in any way in the 4-5 months since purchasing. Terrible customer service, terrible product. Do not waste your time.
