Bimmerworld Rear Suspension Bearings

Anyone who's done BW rear camber arm and/or rear trailing arm bearings, can you comment on how long they have lasted for you? I wanna know if they're fairly sturdy or need replacing every couple of years.

Yeah. I don't think anyone on here has had them for long enough. Ive been on the look out, as I have them on order. They shouldn't be an issue from what I can tell. Spherical bushings are pretty tough.

The tolerances (press fit) seemed on point for the bearings used. Also, the Bimmerworld kits use the OE style sealed monoballs. They will last as long as the factory units as the are just that - modified OE monoballs.

I don't foresee any issues with these.

I have their solid RTAB, I've been running it on the E90 stroker track car for a couple years. Works great.

(I have the one you tack weld on)

Yeah I read that, but wondering if the bearing stiction is really an issue when you have the weight of the rear wheels, brakes and hub levering down on the rear trailing arm. That's certainly a lot of weight and shd more than overcome any stiction in the RTAB.
