Lets Talk Bumpstops

[TitanFox]

I'm looking for some insight on what people have done for mounting and positioning on front and rear suspensions.
Rear suspension is a solid axle so that's pretty straight forward.
My front suspension is a strut rod setup so it's alittle more complicated. Pictures would be awesome if you have some.

Typically, McStruts have the bumpstop on the shock shaft it self.

I thought about running some small ones on them but most look to be an inch or more and that will limit my travel to much.

I am not sure what you are trying to accomplish then. Can you explain the problem you would like to solve?

Trim them to whatever height you need.

That is true I might be overthinking it

I don't want to bottom out my coilovers on compression and damage them. So I think it comes down to one that go on the coilovers or one that mounts to the frame and stops my LCA.

In that case you definitely want them on the coilovers. Trim as needed. If you stay away from the polyurethane ones and get the foam rubber ones they are quite progressive and leaving them tall may not be an issue.

Years back I was messing with some Koni coil overs and Koni advised me to trim their included bump stops to my desired height. I remember finding a chart with some numbers for the stiffness of the bump stops and I believe I ordered some different ones and then trimmed them to fit my needs.

As others have mentioned, I'd go with something like this: https://www.summitracing.com/search/...ock-bump-stops

There are also a number of lower cost options from OEM strut applications for modern cars. The "best choice" depends on what rate you're after, how tall they should be, and your shock shaft diameter. Just about anything will be better than nothing, but getting your setup just right will take some testing and iteration.

I ended up finding these: https://www.summitracing.com/parts/aaf-all64330
Which gives me some choices on the stiffness and height. But to start I'm gonna make my best educated guess and see how it goes.
With the setup I have, under full compression I have .38inch on travel left on the coilover. So the .5 thickness should be a good starting point.

bump stop is a misnomer, they are jounce bumpers and should be part of the spring package, they are secondary progressive springs that only come into play when the suspension travel exceeds a certain limit.
If you are trying to prevent you shock from bottoming out you need a shorter shock or stiffer spring then ad the jounce bumper as a secondary progressive travel limiter this way you don't end up with a sudden solid suspension.

What coil overs are you using?
Any pictures of the suspension?

When you say under full compression you have .38 inch travel left on the coil over, what is stopping the suspension from moving more (hitting)?

I'll be using viking coilovers C417

For the wheel travel I worked out having 3.5inch compression 2inch extension with a leverage (motion) ratio of .71. Which gives me some extra travel on the coilover. But to answer the question lol nothing will stop it.

Nice calculator I found
