Unfortunately KW does not disclose their progressively rated spring rates, so I cannot comment.

Bart@AUTOcouture · 04-01-2011, 05:39 PM

Rear drop, .5" max? That's less than RD springs, this true?

These are the specs provided by KW. The RDS springs are rated for 0.7" drop in the rear. But in reality, we found that this KW sleeve-over kit can actually lower more than what the provided specs are...

Installed pics and more info to be posted soon.

Will this be suitable for use with the competition package EDC?

Here are some pictures from an installation we did this past weekend.

The vehicle is a 2011 E93 M3 in Jet Black.

Here are some pictures of the car at stock height.

Here you can see the OEM Front Suspension Setup

Here is a comparison photo of the OEM setup vs. The KW S/O kit

A few more photos of the KW S/O Kit, take note that this kit utilizes the OEM top mounts (front). It simply replaces the springs, spring perches with adjustable units, new shock dust boots (for the rear), in addition to replacing the soft factory bump stops with reinforced / slightly shortened KW ones.

Here are some pictures of the end result. The customer desired a minimum of 1 finger gap F/R. So we adjusted it accordingly.

Please note that we still had approximately 15mm or 0.5" of additional lowering adjustability in the front and about 10mm or 0.3-0.4" of additional lowering adjustability for the rear. Also take into account the fact that the car will lower an additional 3mm or so after the springs have fully settled in. As such, despite the rated lowering specs provided by KW - we estimate that the maximum lowering specs for this S/O kit is 1.4-1.5" F / 0.6-.8" R.

You just made Steve Dinan really mad.
KW EDC suspension kit with a lot lower price than Dinan. This is the win.
