Stock springs with cut bump stops?

Curious as to what would happen if you ride stock springs with a cut bump stop (from a lowering spring install). Yeah there will be more travel because less of the bump stop is there, but what does that mean?

Stock springs have a longer block length so there is the possibility the spring would block before hitting the bump stop.

Suspension will be effectively softer through it's typical range of motion so expect more body roll and waiting longer for the car to take a set in corners and transitions.

Might be useful for some rough roads or a sweepy flowy track on non-sticky tires

Cutting a bump stop is effectively softening the spring rate

I strongly disagree with all of that post. The car doesn’t “set” into corners on the bump stops. You have a serious issue if you’re riding the stops in a corner. The bump stops are there to prevent full block of the springs. Removing the bump stop doesn’t change the spring rate at all it simply removes that safeguard of fully blocking the spring.

The car on OEM springs with cut stops will ride just like stock unless you hit a big swell in the road or large bumps in turns and in those situations you may block the spring before reaching the bump stop.

Sooo basically, having cut bump stops is effectively the same thing as having no bump stops?

It really depends on how much is cut off and the exact block length of the OEM spring. It’s hard to say for sure but yes, if it blocks before reaching the stops then they are effectively useless.

Why not just get shorter bump stops? It's $100 for 4...but it's technically "doing it right".

I've thought about it because I hate permanent change (e.g. wide body leaving holes), but the only ones I've seen are the eibach ones that sells for $25 each (yiiiikes). I don't even know what size you get unless they give you 1 of each size from the picture or something. But eeeeeiiither way, this was all theoretical because I don't even have lowering springs or cut stops. I was just curious. Thanks guys lol (:

It absolutely does corner on the bumpstops on stock suspension.

I bet most coil springs have more travel before bind then the damper has.

I’m not saying it isn’t possible to reach the bumps but to say the spring rate changes with bumps stops is just nonsense.

I just assumed you had lowering springs with cut bumps and wanted to return the car to stock without buying new bumps. Hahaha

The bump stop acts as a spring too. So there is an effective rate change.

Good springs are $70 each, $25 for a quality elastomer spring is a bargain.
