Although, I completely understand that riding on bump stops is not good at all is still better to hit the bump stops than bottoming out constantly.
I highly doubt one is riding on the bumps stops like all the time and if that the case then that is at least of the problems and still better than blowing up the struts/shocks quickly.

Why do you keep talking about bottoming out the the shafts? You're still running a bump stop, albeit a slightly shorter one. They prevent the shock from bottoming out. Stop saying that. It makes no sense. OE bumpstop lengths are not chosen to be just the right height so the shock doess't stroke out. Far from it.

BMW designs some of their suspensions to just about sit on the bump stops at stock height. The M3, for example.

You want to trim your bump stops to keep something resembling stockish suspension travel, period.

Running longer stops and lowering your car at the same time is just plain awful advice with no logic behind it. It's completely contrary to what you'd want to be doing.

If you're adding enough spring rate, you could argue that you can leave the stock length stops in, fine. But you'd never go longer, at least in a street application.

With a longer bump stop, you'll get into it sooner, and thus fully compress is sooner. That makes for a brutal ride, constantly "bottoming out" the bump stops. Maintaining or increasing suspension travel is good for your ride quality. Shortening it is bad.

You ever see lowering springs come with LONGER bump stops?

Actually yes, my Eibach Pro kit I purchased in 2009 came with suspension limiters to prevent bottoming out on the stock struts and shocks.
They could be installed or uninstalled after the strut/shock assemblies are on the vehicle.
Something like these:

You certainly didn't get them for an E90. And if you did, they're supposed to be used in place of the stock bump stops, not with them.

Yikes man, stop giving advice and start reading.

Limiting the suspension travel even further on an E90 is THE WORST thing you could possible do. So frustrating...

Negative, they are add on and suppose to work in conjuction to the stock bump stops. I have seen them in kits for MB, Audi, VW and BMW too, although I agree, not for e90. So there you go, I give you the argument: not good on e90 due to short suspension travel out the box.

That's funny, this whole thing started with you recommending to do just that!

I corrected you, and said it was a horrible idea to run longer stops.

And you proceeded to argue...

Jesus man

PS, I read the application for using the VW limiters you posted. Yeah, on a Jetta, if your car came with 16" wheels, and you're running 18 or 19".

AKA, oversized wheels, and they need to limit the suspension travel to prevent the wheels from smacking the fenders.

Do you do any research before you post?

Those limiters have NOTHING to do with preventing a strut from stroking out.

It's a ricer add-on to limit suspension travel to prevent fender damage on your lowered car.

Those from the photo above are just for reference. Mine came with the Eibach Pro Kit lowerig springs.
It was not wheel related as there is no wheel designed for particular model by the vehicle manifacturer that will run into interference with the fender.
Wheel specs as diametar, width and offset are all calculated in a way that they will work on a specific model even when lowered as in case of when car is fully loaded, like passangers and luggage.
If the wheels are from a different model that is somethig else.
Anyhow, I was in hopes that my previus post was sufficient to full fill you need to keep beating dead horse.
Guess not.

feure your idea is basically the "packer" idea.

i've seen discussions on them at grassroots motorsports. people use them for adjustments for off-road. I'm curious about them for autox since as you note they are easy to put on and remove.

[chris@strutmonkey]

For Koni, use the stock bumpstops if you are using the stock springs.
Best regards, Chris

Even some OEM BMW bumps stops come with "add on" rings. They are from the Performance suspension. I guess that is the BMW version of "packer idea" .
