subframe fixes

[azrael]

I think BMW should be doing this as a preventative fix. If people do it themselves and get it wrong I'm sure BMW would use that as an excuse.

Unforunately Duncan, your car is a good illustration of what I have been saying for a while - that the stress cracks aren't isolated to the mounting floor pan itself - i.e. it is to do with the load being carried incorrectly through the body structure, cause premature fatigue fractures (i.e. the void in the bottom floor sheet metal).

I'd get that welded up ASAP before it drops the whole floor out of the car (which it will).Good job I sit up front then !

duncan there not the usual types of cracks you see tbo. possible caused due to your cage/suspension. i'd make sure you swop your suspension over as even if you dealer is on your side. when they take pics and send them to bmw uk the coilovers may just be seen and you'll get rejected.
alot of the bmw dealers are ok with mods ect, the dealer who did mine even fitted a limiter kit before it was kds'd.

Neil333 - one tube is enough to do both rear mounts - If you are doing the fronts, then you need two.


Thanks for the info, its much appreciated!

Im confused now if i want to do both left and right side of car will one tube of epoxy do both or do you need one for the left and one for the right.The bmw instuctions just say to pump the whole lot onto left void as they dont do the right side,just wondering as i need to do two cars and maybe pinkpanthers so dont want to order too many.
