This is the H&R Street Performance coilover kit, part # 50402
It was fitted to a car for about 8 months and used for less than 5000 miles.
The kit includes everything – the four dampers, four springs and two assisters, all the mounting hardware.
The dampers do not appear to be leaking any fluid, the rubber sleeves for the front dampers are not torn or chafed.
There was a slightly damaged thread on one of the rear spring perches caused by cross-threading during the install, but I have replaced the entire perch including the threaded section, adjuster and cup.
H&R claims the kit lowers the car by 1.2-2" front and 1-2" rear.
It does lower the car nicely but there is no fender rubbing with stock 18" wheels or 19" wheels of the correct offset.
The ride is surprisingly good. It's really not much stiffer than stock, and feels comfortable in the city yet is incredible in the corners.
The kit has never been tracked.
It retails for about $1600 new but I'll sell it for $900 or best offer.
The kit is in its original H&R box but it is obviously very heavy, so I'd prefer if it could be collected from Los Angeles rather than being mailed.
