Rear camber for lowered 4.8is

[dhyrk3]

Calling all lowered 4.8is owners, Has anybody tried this yet?

Rear Adjustable Camber/Toe Bushings - E60 E63 E65 E53 X5 - KMAC Street - Turner Motorsport

How and where do you install them?

If you dial out most of the toe in the rear your tires should wear evenly even with some extra negative camber. if you have excessive negative camber in the rear check your rear control arms and rear ball joints for wear.

I set my 4.8iS 1" lower and see no need for those.

Thanks. I'll change the ball joints and upper control arm this weekend. I've read somewhere that even if there is no play when you wiggle the wheel, the arm, joints, etc might still be shot.

Right now, my rear is round about an inch and a half from the fender flare to the tire resulting in my camber at -3.5 deg.

Have an alignment done.

been thru this just recently, i have a face lift 3.0d sport and i lowered it with eibach springs.

there was not enough adjustment left to reduce the camber so i had the kmac kit fitted.

and then the alignment done, new tyres and now its all perfect, we tried the dialling out the toes in and in my case that did absolutely nothing.

only down side and its in my view minor, as the bushes are now synthetic and not rubber i notice a very slight creaking noise at low speed, like when backing out of my drive way

all said a great option.

however the fitting of the bushes was a mission, and a little more involved that the instructions, and you really need to remove the lower arms and use a press to fit the new bushes.

am i happy with the end results, defiantly, i cant afford to be replacing rear tyres every 20 minutes hehehe

In order to check the rear end suspension for play you need to release the pressure exerted by the air spring (or coil spring). You can do this with an extra jack as shown in this youtube video (VAC Motorsports - Correcting tire wear on a BMW X5 E53 - YouTube)

Or, if you can put the back end up on jack stands and release the air pressure out of the air springs by slowly bleeding off the air from the tanks in the back. Once the air pressure is released, then you can check on the arms and balljoints for play.
