What struck me is that although the weight of the car is in perfect balance, the rear shocks are quite a bit stiffer R/F = ~3800[Ns/m]/~2800[Ns/m] = ~136%. This ratio is quite larger than fi the M3 shocks where front and rear shock compliance is largely equal (referring to E9X M3 ZCP shocks).
In service to OP's selection of upgraded shocks, I hope the more experienced shock-ers among us can also help all of us understand the 1M OEM setup better.
I would assume significant reasons could be to battle understeer (car will roll & pitch towards the outer corner front wheel) and to prevent excessive wheel torque jitter ???
