Increasing front camber without installing camber plates or LCAs
It seems like this has been beaten to death in these forums, but I'm starting a new thread because I couldn't find answers to my specific questions. (I'm sorry if I missed them in another thread.)
I autocross my m235i in the F Street class, which doesn't allow the installation of camber plates or changing out the LCAs. Last weekend, a guy at an autocross (AAX at Crow's Landing CA) said that I could drive out the pins on top of the front strut towers and gain another 1/2 degree of camber adjustment. Does anyone have any experience with this? I'm also considering installing eccentric camber bolts (aka crash bolts). Does anyone have any experience with this? If you've done either or both of these, how much camber did you gain? Also, if you're an autocross rules guru, there seems to be disagreement about whether these are legal modifications or not; people I trust equally came down on different sides of the question. (The one I want to believe said that there was a rule change this year saying that if a part [the camber bolt] is listed in the official BMW parts catalog, it's now SCCA legal for my car. Another long-time autocrosser said that removing the strut tower pins is also legal.) Thanks. Last edited by Bareiss; 08-22-2018 at 11:12 AM.. |

What I heard is removing the alignment pins should be legal for SCCA street class, camber plates will kick our car into another class.
There's also a thread about getting little more negative camber by changing the steering knuckle, which is a "factory approved" repair method which will also keep the car in street class: https://www.2addicts.com/forums/show....php?t=1344701 btw: I was also in Crows Landing last weekend! It's always nice to see more 2 series on autocross |

I would also like to know more about this. After all, if it's true that I can get 1/2 degree of negative camber without any major modifications, I'll take it.

The alignment pins are on the tops of the strut towers. You can see them clearly when you open the hood and look at the locations where the towers are bolted.

There aren’t alignment pins on the F22 like on prior Exx 1 and 3 series. There are cast dimples for location and threaded holes in the top plate. I don’t think there are any slots above the holes, either, but I haven’t removed the bolts to have a look (another change from Exx models that used studs and nuts). I think power tools and cutting would be needed, as opposed to just driving out or unscrewing the location pins that was possible on older models: https://www.realoem.com/bmw/enUS/sho...diagId=31_0950

There are two alignment pins each strut tower but these are cast into the strut (the “dimples” mentioned in the previous post) so these cannot be removed. Additionally, F22 strut towers do not have any eccentricity to the bolt holes. Perfectly round. So even if you tried to knock out the pins, you wouldn’t get anywhere and wouldn’t be able to make any adjustments. In short; this trick doesn’t work for F22s. |
