Which bump stops with BMWP springs

Hi All,

I have a new set of BMW Performance springs. Since the performance shocks are NLA, I decided to go with Koni Orange (Str.T).

Any suggestions for the correct bump stops to run?
Would ones intended for M Sport suspension be fine (BMWP should only be about 10mm lower) or should I go with something different like E36 M3 front/Z4M rear like some people do with lowered suspension?

I don't want it to over-travel...running a slightly aggressive width/offset in the rear and I don't want it to rub on dips.

If it matters, the springs are T1's per vin matching (version intended for the lightest E8x's).

Recommended by GetBMWparts when I bought my spring from them:

Front - 31331096099
Rear - 33536788905

I'm on T2's, but shouldn't matter since spring/VIN matching is all about a consistent drop.
