- Lower the vehicle to the floor for the final tightening of the frame mount through-bolt.
- Once the full weight of the vehicle is on the floor, tighten the frame mount through-bolt nuts .
- The suspension components should not be tightened until the vehicle’s weight is resting on its wheels.
Adjustable Rear Camber Arms (pair) – BMW 3-series (e36/e46) and Z4
(Sets For 2)
Why you should use camber arms on your BMW:
If you have a lowered BMW and have run out of adjustment with the stock camber arms.
If you have a track car and are looking for increased camber adjustment, light weight, stronger components, and increased suspension handling.
Easy and simple to adjust, with the main adjustment point out by the wheel, so there is no need to work around the exhaust or subframe to adjust camber.

(* Tire technology typically evolves slowly, which makes the Camber Tire from Optima Sports noteworthy. The Camber Tires inner sidewall is shorter than the outboard, which tilts the top of the tire inward, toward the car. This increases the tires negative camber, an alignment specification that car racers use to enhance grip while cornering. On the highway, however, too much negative camber puts only the inner portion of the tread in contact with the road, resulting in uneven wear and dicey straight-line stability. The Camber Tire maintains its tilt while keeping the tread flat on the tarmac. *)Why are adjustable camber arms better than the stock ones?
Unfortunately, for a lot of cars, the stock camber arms have a minimal amount of adjustment. In a car with an aggressive camber curve, you will have too much negative camber in the rear, more than can be adjusted out with the stock adjusting eccentrics if your car is lowered significantly.This is important if you are involved in road racing or autocross or if you just want to maximize tire wear for street use.
The adjustable camber arms, offer a much wider range of adjustability than stock. The have a left and right hand thread on the adjuster itself so adjustments are an easy twist away without having to remove the ends of the arm when setting things up. This greatly speeds up the process of aligning the car.
What effect does camber have ?
Camber is an alignment setting on your car that denotes the angle of your wheel and tire in relation to the road surface. Camber can be zeroed out, negative, or positive. When camber is zeroed out, it means that your tire is perfectly parallel to the road surface. When camber is negative that means your wheel and tire is tilted inward at the top. When the camber is positive the tops of the wheels tilt outward.Above is a diagram to help better explain.Camber can affect a number of things including tire wear and grip. The wrong camber settings can cause uneven tire wear and reduced tire life. Too much negative camber and your tires will wear out more quickly on the inside edge of the tire. Too much positive and your tires will wear out more quickly on the outside edge of the tire. It is important to have your camber properly adjusted for the type of driving you are doing.Road race and autocross cars tend to use negative camber settings to maximize tire contact patch and grip in high speed turns where the car transfers weight to the outside tires. Drag race cars are set up to keep a neutral camber setting to maximize tire contact patch and grip in a straight line. Oval track race cars tend to use negative camber on the outside (right side) tires and positive camber on the inside (left side) tires as they only need to worry about tire contact patch and grip while making left hand turns. Outside of oval racing, positive camber is almost never used.
How do I know if my settings are right?
If you are want maximum tire wear and setting your alignment for normal every day street driving, it is best to stick within the factory alignment specs found in your owners manual. If you are road racing or autocrossing, you will want to dial in more negative camber, particularly in the front tires. If you are wondering how much negative camber you might need, the best way to tell is to take tire temperatures from the outside, middle, and inside parts of each tire after a few hot laps to tell which parts of your tire are heating up the most. If your outside edge is heating up much more than your inside edge, you need to dial in more negative camber. Lacking a tire pyrometer, you can also monitor the tires wear, if the outside edge of the tire is wearing quickly, then more negative camber is needed, if the inside is wearing faster, more positive camber will help.
