DIY for shaving front guide supports?
I am looking at going with either an Eibach or H&R setup and want to shave the front guide supports in the front. I have searched for a DIY to no avail.
This may be extremely simple but I don't have the parts in front of me. I am mainly interested in how much to shave off. Are you just removing rubber? Whats the best tool to use, maybe a belt sander? |

From my experience I found the best way to do it, is with a lathe and a sharp parting bit to slice through the rubber (I used one of our small lathes at work and ground up a parting blade from a hacksaw blade) then a carbide insert (or HSS shank) to machine the metal portion. I tried a miller but the carbide inserts for cutting metal didn't mill the rubber at all, as you could imagine the rubber just deflected and squirmed around.. |

Bumping this. There are other threads about the shortening of the strut mounts (for more bump travel), but this is the only one that is specifically about how to do it (DIY).
I'm on B8s and swifts, and still feel like I'm on the front bump stops too much, so I've bought a set of new mounts, and plan to shorten them 1/3" or ~8mm. I've shaved the internal bump stop of bilsteins (b6) previously, on E46 m3, but am chosing this route instead since there's a known solution (besides installing camber paltes with thinner stack heights). My father is an actual machinist, and I assumed this would be no big deal. His concern was that the steel bearing being encapusulated in rubber will deflect. He suggested just taking a hack saw to it, even attacking it from different points to ensure a straight cut, then cleaning up on the belt sander if necessary, would be best. Perhaps the rubber is so stiff that it doesn't deflect enough, in the lathe, to be dangerous, but will the cut be even enough? It also seems relevant to mention that even if the cut (by hand, hacksaw/sawzall) were not perfectly parallel to the top plane (top surface that mates to shock tower), the rubber will slightly deflect to correct, and not so much that it would cause pre-mature wear. Your cut needs to be good enough, of course.

BTW...Most E36/E90 camber plates are same stack height as stock, or even a little taller, unfortunately. -Mark in St. Louis |

Interesting, too, to hear that you did 10mm. I've seen 8 and 8.5mm (.33") mentioned. I wonder what the point would be where it's be too short - I guess all the way up that tapered rubber? IDK, I'll probably just stick with 1/3". In Re plates, I guess E46 is the big winner in that dept. of regaining travel. Glad you mention that, as I was contemptlating the sense in buying new stock mounts (not cheap) if I plan to move to coilovers in the future. I was worried it might not be a great idea with something like Ohlins, but if plates don't gain you any more travel anyway, I'd be set with my cutdown stock mounts.

I had a bit of a conversation with Jason @Vorshlag, and he mentioned that he couldn't get the stack height any less than stock, with the bearing being used...as I was asking about shaving down the bottom spacer/plate on his camber plates...but that is a no go. -Mark |
