This will be a complete new setup from struts/shocks too springs. So I have no data to go off of besides what I read from your posts on some others.

From what I've seen and experienced, 8" is for stock rate like 143lb up to like 200. Once around 300-400, 7" is good. Then after 400lb 6" is ok, especially if you get the extra travel type.
You won't have to worry about rubbing the spring perch with linear springs and those wheels.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram

IMO, using stock mounts defeats a very useful feature of aftermarket coilovers/plates for us - reducing ride height for free through reduction of stack height in camber plates from GC, Vorshlag, TMS and probably others.
If you just want stock like height (14"+) then you'll have plenty of travel I suppose.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram

FWIW, Ohlins comes with a 8" 400 front spring and that provides almost an inch drop with stock front mounts.
If you try running a 350 7" spring at 13.5 ride height, you will be almost at the very top of adjustment threads on the collar after preloading the spring appropriately (ride height and spring preload same adjuster).
I tried a 336 7" spring and could not get it to more than barely above 13.25 after maxing out the adjustment collar/preload. The tire rubbed.
Rears at 628 I believe are 6" long (they might be 5", ill need to check).

Do you know the rear spring rate for the Ohlins? I’m assuming the 400# F are for the R&Ts?
