Rears started chipping powder coat after a year. They are rusting already. I only drove in the summer. I need to send them in for warranty

What made you choose this particular product?
Koni has a great reputation for quality and performance, and this coilover kit seems as though it's a great value. I feel that the components are of good fit and finish. I'm glad to have ride height and rebound adjustability, and I believe it'll serve my purposes nicely. The car looks so much better lowered, and the ride height adjustability allows me to fine tune the corner height. I wish the kit had compression adjustability in addition to rebound like some other similarly priced offerings. KONI themselves have told me that the spring rate on this kit is a bit soft - if I need to stiffen things up in the corners, that I might go for an enlarged rear sway bar. Additionally, I expect that a haldex controller will result in better overall dynamics. All in all, a nice kit and a good brand. Not sure if I could have justified another 700$+ for the Bilstein PSS10s that I'd been considering. They look great too - mirror polish, grey springs, and red anodized front spring perches and locking rings.
What were you trying to accomplish by adding this product?
Lowered ride height for asthetic improvement as well as imroved handling
Was it easy install? Any installation tips that will help others?
It was pretty straightforward. Helpful instructions put out by ECS Tuning.
Any additional comments?
Spring rates almost too soft it seems... But good ride quality.
