Alignment Help! - BMW 3-Series (E90 E92) Forum

Maan · 10-25-2012, 07:09 PM

I put on the H&R sport springs 3 day ago. Got the alignment done today and front driver side camber is out of wack while the passenger side is fine. The guy tried loosing the screws on top of the strut and still couldn't couldn't get the camber to get into spec. Help me out here. I checked the tire pressure and it's 45psi on both sides. Measured the height and it's 25-1/4 inches from the ground on both sides.

Brand new rims and tires installed less than month ago.
19' Avant Garde M355
tires: Hankook V12's 265(R) and 235(F)

Any alignment experts out there...

Anyone? Help me out here. Someone with similar setup and what type tire wear do you get in the front running more then -1.0 camber in the front? And running close to -2.0 camber in the rear?

Not related to alignment but 45 psi tire pressure is way high, use what's listed on the driver side door.

Lowering the ride height has consequences, namely it increases negative camber and toe out. The adjustment range built into the stock car is only sufficient at stock ride height, not when it's lowered. The extra camber as shown on your alignment report (thank you for posting that) isn't enough to cause excessive tire wear so I wouldn't worry about it. Your toe is a little much for my taste but it's within spec.

oh ok thanks for the input. Is it a good idea to get the passenger side to same camber as driver? Is that even possible?

It is possible to get both sides even but it doesn't have to be and in most cases isn't. The difference between either side in your alignment won't be noticeable.

your stock struts have no camber adjustment. So youre going to be stuck with whatever the alignment measurements are. It could be that the shops machine is uncalibrated. You wont feel a difference but your tires wont wear out the same. If you're really worried you can buy the vorshlag camber kit from hpautowerks

Ride height may not be accurate, directly affecting camber. You might consider investing in camber plates as it appears you're lowered.

First & foremost, alignment/ride height measurements should be taken when the vehicle's on a level surface. Can use a water level to verify.

Then, ride height's generally taken from the top of the wheel well arch sheet metal to the bottom of the rim, true vertical. Stock front measurement for a 19" rim is 24.60".

How are toe & camber being measured? Should do toe to a zero thrust angle line.

Having both extra camber and toe may result in increased tire wear, as the tires are dragged more across the road. When I lowered my car, the front camber went up to just over one degree and the rear to almost two degrees (which was lessened to about 1.7). I checked out some M3 suspension specs, and reduced my toe-in front and back to about 2/3 of what you have. The car still tracks straight, and the turn-in has noticeably quickened.
