I don't care if I have to get a kit to put the car back into alignment, I just want to know from someone who has done it if it is possible or this guy is stating the truth. A set of tires a year is bad enough with stock specs, if its worse after lowering, I would really like to know before I go and do it.

The kits work!

Call Rouge, ECS, BavAuto........they will give you the max drops their kits can correct for better then ANYONE on the forum.

Curious if anybody has seen these before. I doubt I would trust theses....

YUGO Front Camber Bolt Kit GV Series New | eBay

I did some research on them, a lot of others use a kit similar to this.

Anyone know the difference in a kit like above and this one?

KMAC BMW Rear Camber/Toe Kit 5/6/7 Series E53 E60 E63 E64 E65 E66 - Import Auto Performance

mate ive already told you I HAVE DONE THIS using the KMAC kit YES it works

Where exactly does the kmac kit get installed?

rear suspension lower control arms inner bushes, the factory ones are pressed out and the new offset bushes ( Poly) are pressed in, the instructions say you can do it on the car.

but thats not the case you need to remove them

the the factory bushes have an eccentric/offset bolt whereas the KMAC kit has an offset hole and the whole bush is able to rotate in the shell to allow for camber adjustment. allowing for vastly more range of adjustment. in my case the wear on the rear tyres was acceptable and the stock height, however once lowered there was insufficient scope for adjustment to correct the now excessive rear camber, hence the reason i went with the kit.

in my case i now have 0 camber so perfect wear across the tyres ( 315,s) however as i said earlier if i find the front wearing faster than the rear i will get some negative camber dialled in to the back. to even the wear and to improve handling.

the negative camber in BMW,s is there for a reason , and in my case now i feel the car has lost a marginal amount of cornering ability with the 0 camber.

its a balancing act for a road car between camber and tyre wear,

Get upper arms in the rear to get better camber adjustment. I didn't like kMac rear camber kit, I would stay away. The x5 with rear air suspension can handle a one inch drop but the ride will get sacrificed a little bit. Bilstein HD struts and shocks are good with lowering springs. Good luck

+1.

That's why I posted the adjustable arms info in my inital post, Not a fan of the cam adjusters because fine tuning the rear camber is less touchy with the arms.

Would not go with ANY no-name/made in China suspension components. You may end up with fasteners that strip or plates that are so thin they bend/crack/break under normal stresses.

I'm talking about genuine BMW upper arms. Over time they sag and the suspensions camber goes negative
