I am considering similar set up, but concerned about strut mount strength.
If you’re referring to the rear upper damper mount then the F8x doesn’t require any additional structural reinforcement when running a rear coilover setup. The 900-1200 lbf/in rates discussed in this thread are for divorced spring-damper (OEM) setups vs. 400-600 lbf/in rates for rear coilover setups. You’re trying to match wheel rates when switching between the stock setup and a coilover setup due to different motion ratios.
