KW V3 Coilovers Ride Height
So I have had these on my car for sometime and played around with the ride heights.
At first I went for a better stance. Then I decided to measure and stay within the "recommended ranges".
However when I follow their manual which states 105-120 mm (Center bottom bolt to adjuster) the car in the back looks slammed! measured to 120mm
The grip, performance, ride quality is amazing though?
When I had it to fit a finger in the gap the car was too stiff in the rear / traction lost etc etc. Plus to do this it was compressing the main spring.
I am confused?
I have the front dead in the center of the range 290-310 mm (I have it at 300 mm) It is a bit too high.
One thing I noticed is that their B measurement which is center wheel hub to fender is much greater in the back 315 - 340 mm. Total difference is 25 mm. But A diffference is 120-105 mm = 15mm?
Maybe the manual is incorrect and it should be 105-130 mm?

Lowering
Front Lowering: 0.2" to 1.2"
Rear Lowering: 0.2" to 1.2"
I looked at other manuals for other cars with KW V3 and it seems A and B differences are similar ...

Wow, good catch on the wheels.
I meant that I am at the MIN lowering range as recommended and it seems too low!?

I've never seen a worse method of measuring ride height. Fender arches are terrible reference points. The factory (rightly) uses suspension bolt height from ground. Anything else, even measuring the installed height of the spring, is just guessing. I've tried them all, nothing beats setting ride height by the actual suspension.

With the weight distribution you are right. I'm not going to get it that great.
Unfortunately I only measured from center bolt of the bottom strut to the top of the adjuster.
128 mm back and 292 mm front
And this is what the alignment shows. Time to maybe look at those other accessories to have some adjustments for camber.

0.04 degrees toe out in front, OEM spec in the rear. Does everything well for my street driven car.
