    Default Bump stop use with Koni's?

    Ok, with all of the current talk of bump stop use I thought I'd ask this question.

    Just got a set of Koni's for the front of a friend's '95 525iT of off BFC. We're not changing the springs on her car, just installing the Koni's as they were a good enough deal that it would've cost just as much to get a pair of Boge inserts. And really, who'd run Boge when you can run Koni's at the same price.

    Anyways, do Koni's need bump stops? Full length factory ones or shortened ones? Remember, I'll be reusing the factory springs so I'd imagine I'd not need to run short stops if I need them at all.

    If you check Dinan's site, you'll see bump stops in the picture of their Koni's so I say use them. I put Koni's in mine with M-tech springs and re-used the old bump stops with about 1/3 to 1/2 cut off.

    Check out the X5 bumpstops, about 1.25 inch shorter and no cutting involved.

    Factory height don't need cutting but I'd cut 1" off... due to settling of old spring.

    I used E46 M3 bump stop. It's about half the height of the stock e34 bump stop. I running Eibach springs and Koni Sports.

    Good to know that those work as well. Did you use the regular E34 parts for the dust boots, mounts, etc?

    Dust boot didn't quite fit. E46 bump stop was very slightly wider and the notch were it holds the boot was different. But I made it fit with little bit of force...
