Someone can correct me if I am wrong, but the point of using the e36/e46 bumpstops is to retain the same spring travel so your not bottoming out. Lowering car = decreased travel, so to retain stock travel you need different bumpstops.
I use RD Sports with e46 M3 bumpstops and never bottom out, even on big highway dips at high speeds.
