How often are you "bottoming out"...aka bouncing hard off bump stops?

Recently moved from E46 M3 to E92 M3 w/Fortune510 10k/14k, and I'm surprised how often I "bottom out".

From what I can tell the Fortune 510 "ride height adjustment" has no impact on shock travel, as the body and spring is adjusted as an assembly...BUT if run "slammed" I'm wondering if the geometry is "compromised". Meaning the shock may still have plenty of travel but the control arms "run out of range of motion" and "bottom out" (against?) with less travel than designed.

I tried searching with no luck. Where can I find information about "min ride height that maintains full travel"?

Thanks,
M.J.

From my experience, with spacers the shocks bottom out earlier also.

That is why I removed them, don‘t like spacers.

How would spacers bottom out the suspension sooner if the wheels/tires arenít rubbing?

Well the spacers would technically add more leverage the wheel has on the suspension. No?

Yes...and I am running 15f/12r but I'm also running 10k (560lb) front springs...which my gut is telling me are "too stiff", but I'm "bottoming out"

A proper suspension shouldn't bottom out abruptly. I have only experienced that with lowering springs on factory dampers

That is my expectation as well, but my car is also setup very low. So I'm not sure if the ride height is the issue...or? Wondering what to evaluate first...

Any insights would be appreciated
