Front: Hypercoil 6" 700lb 2.25 diameter
Rear: Hypercoil 6" 800 lb 2.25 diameter
2x 2.25" hypercoil helper springs / spring guide sets also.


It's hard for me to get a good frame of reference for the spring length.

Currently I have KW V3 and it is a little too low in the rear on the highest setting. Anyone have any advice on spring length or does 6" sound good?
Believe it also comes down to sway bar clearance. I know bimmerworld recommends running 6" in the rear at the top position rather than inverted in order to clear the sway bar.

Did they tell you to run the rear inverted with the remote setup or right side up? I don't believe they supply the offset spacers anymore either to push the shock further from the sway bar as they feel it moves the shock travel outside of the center line of travel.

I am wondering the same as you. Currently have 1WNR divorced that I am thinking of converting to a rear coilover.
I didn't get to the point yet where they mentioned specific installation orientation, but they did mention sway bar clearance issue over the phone. They seem to be standing behind the setup I posted above, but at the same time I wasn't sure about how it would affect ride height adjustment range.
6" with a helper should give you plenty of ride height adjustment and sit higher than the KWs you have. I am curious to what they tell you about installation orientation.

Also - I believe the lower spring rate should be in the rear.
Thanks @rborane !!! Exactly the confirmation I needed.

I might have gotten the fronts/rears mixed up as it was not explicitly called out on the quote.
