2017~2025 CX-5 H&R or Eibach lowering springs?

[teddymac]

@teddymac saw your post about the longer B6 rear shocks for cx-5 and curious if you had issues with cutting so much off the progressive bump stop off with corksport springs.

We have bad roads in PNW and worried about taking a corner at the limit and hitting a bump that unsettles the car when hitting the heavily trimmed bump stop since the progressive part of the bumpstop is removed.

For Corksport + B6:

No issues.

For Eibach Prokit springs + factory shocks




Seems like these bumpstops act as a secondary spring. I measured the B6 cap and looks like it’s 20mm taller than factory, so considering cutting 2 rings off the rear bump stops (one less than the green line above)

I haven't had any issues since trimming the bumpstops further than what corksport recommended, to work with the Bilsteins.

If I haul a bunch of heavy stuff though, the car rides on the bumpstops again.

Found this BMW x5 33536773060 bumpstop was the perfect height (90mm for Prokit springs and B6 vs 120mm factory rear bumpstop) and it’s PUR foam for progressive engagement.

The base was slightly oversize poly I shaped to match the factory bump stop and snapped them into the factory mounts. So far it’s working great, no noise over bumps, and great cornering along with new RSB and rear camber arm.
