OP, if you decide to go this route, talk to Harold and when ordering the swift springs, don't go with the 10" rears, go 8s. I went with the 10's and made my car sit too high even on the lowest settings. As per ohlin, you do not have to revalve either.
400F and 800R is more ideal. The extra low rear rate is great for the ride quality and traction, but the vehicle will understeer and you can never get the backend to rotate as much as you would like it to.

It would be the 9" Swift for the back of the E9x.

We like to use the higher quality Swift springs along with thrust sheets.

A photo below with Swift springs, thrust sheets, and the more robust height adjusters.

Ohlins just released BMS MI01 with improved valving and 70N/mm front and 120N/mm rear springs.
