KW v3 Rear Drop Height Inconsistencies

Edit: Disregard, I'm an idiot.


Hey guys, I recently put in a set of KW v3 coilovers on my M2C and have been in the process of dialing in the ride height. One thing I noticed was that the rear drop has not correlated at all to the specs that KW provides in their instructions.

For example, they mention the rear measurement on the adjustment thread (see below) to be between 15mm-35mm (which would be 1.8"-0.8" drop, respectively)



I set it at the lowest setting (15mm) assuming I would get a 1.8" drop, however I only saw ~0.85". Went from 14.1" wheel hub to fender distance to about 13.25".

The fronts I've had no issues with & everything seems to be in-line with the specs in the instructions.



Wondering if anyone else here ran into this same problem with their KWs? Not sure what I can do to go lower for the rears at this point.

From what I understand the drop takes time to settle in, more or less "break in". The springs will continue to settle and lower as you drive for the first few hundred miles or so.

Please correct me if I am wrong as I haven't bought KW coilovers yet but have been looking into them.

Is a ~1" settle distance normal? That seems like quite a lot of movement after final install. I was always thinking this number would be significantly less than that.

Aren't these the same as M3/M4? I wouldn't be surprised if when the wrote the manual they expected more weight on the rear shocks.

Snapped a few here from underneath as I didn't want to take the tire off, not sure how good of a view this gives.






It also looks like the rear spring is bowed out a little. Not sure if that's usual.

There may be a few installation issues, based on these pictures?

I think you're meant to take the steel cups at the top out before fitting the adjusters and main springs (helper springs and platforms go at the bottom as shown).

I think you might be right here, the rubber housing at the top might be the issue. I'll see if I can't get that out, hopefully that'll solve the problem.

You're not the first to make this mistake. Pics of car after fixing?
