I put a set of upr coilovers on the back of my 04 mustang a couple weeks back. Picked them up used on corral for a good price. The kit was basically an outer machined sleeve put over a shock with a spherical hat to hold the top of the spring.
The install was pretty straightforward and uneventful. Went ahead and adjusted the ride height in the rear to make my lower control arm the same height at the front and rear bolt, to make it parallel with the ground. It was all good up to this point, until I stepped back and checked my handiwork. The spring itself was compressed from a 10” spring down to around 5 3/4” length. Also, I had about 2” clearance from the bottom sleeve to the top spring hat. Basically I had 2” travel before it bottoms out.
After talking to the tech guys at upr, they keep insisting the spring rate I chose is too soft. If I put another spring rate on there, and lower it back down, essentially I’ll have the same 2” travel, just takes more weight to compress that distance.
Question is, what do I do? Trash these coilover sleeve deals and go with a “real” coilover?
