Interesting spring rate combo - ~345 lbf/in F, ~685 lbf/in R. F rate appears to be very conservative even for a street setup, especially if lowered 20 mm. The Ohlins DFV F spring rate for the R56 Mini Cooper S is 400 lbf/in F!
Also, these F-R rates are very similar to the rates that came with a different e9x M3 high-end setup that most owners on ths forum had issues with, especially when used on the track with a 0.75"+ drop.
Please don't read this post the wrong way - the Ohlins DFV dampers are awesome - but these rates seem way too soft for a street, or dual-purpose, setup on the e9x M3. Also, glad to see another great suspension option almost on the market for the M3
