Had my competition package M3 on full sport mode.
Honestly though, Eibach springs are still my favorite springs for the E9X M3's. I was actually considering switching back to stock M3 bump stops, since those bump stops are engineered to be progressive whereas the E36 ones are not. I never did end up swapping just bump stops back to stock though, I just went to a coilover setup instead.
I voted option 1, since, like I said, NOTHING is a necessity for track. But I have a question for you guys tracking: Did you guys swap to E36 bump stops on your Eibach springs, or did you guys keep the stock E9X ones? Maybe I might have actually been better off with the stock ones.

I retained the E9X bump-stops when switching to Eibachs. I haven't had any issues with hitting the bump stops on curbs, braking or compressions and I haven't felt any front end instability with hard braking. I am running advanced intermediate with stock everything else and a pretty hard braker judging by my brake pad consumption.
Of course, I am worried now!
