So i just ended up rebuilding with the OEM pistons and got new boots and seals from BMW. For me, as soon as the temp outside fell below 35, they let go. I got a new track car now, haven't been tracking much with the 135i, but will move to stoptech's at some point when I want to bring it back to the track.

Do you have the part# for the OE seals? I plan to install this later this year and maybe the RB seals are just no good. RB confirmed that the OE seals are compatible with their pistons.
