Bump Stops

Hey bros aware me on the E36 bump stops... are they shorter than the stock E92 bump stops? On my 370Z we cut the bump stops down about .5" to 1" or so and that worked well and was recommended by Swift when installing their springs. Can we not do this on the E92 bump stops? I know it sounds a bit ghetto but what are your thoughts.

You can indeed cut the stock bump stops or just purchase a set of e36. I was told mixed information about them. I was told you can run them and some told you can just run stock. So it is up to you

E36 bump stops are shorter and Dinan claims that they add more travel to the suspension. The OEM bump stops are taller but they are designed to compress and are part of the suspension travel IMO. I had Eibach springs and didn't change the bump stops without adverse effects on the street (never used them on the track). I haven't experimented with any other springs, or bump stop scenarios so I can't say whether it is a good or bad move to change the stops.

They're cheap so it doesn't hurt to put them on and keep a bit of travel

I had them put on with my eibaach springs. Im happy.

the eibachs lowered the front .8" and the e36 bump stops are about a half inch shorter. Its a good compromise and better than keeping the oem bump stops IMO. Either way seems to work fine though.

I've yet to see any confirmation that the E36 bump stops behave in the same way as the E92. Thus I'd be wary about using them as the E92 suspension has been engineered to work as a complete unit, including the bump stops.

If the E36 bump stops do behave in a similar manner and are in effect a short copy of the E92, then they would be a good way to increase suspension travel without impacting the overall behaviour BMW engineers spent a long time developing.
