A top seller! The TMS Adjustable Rear Camber Arms are the only adjustable arms approved for Grand-Am Koni Challenge Racing - E46 M3, E46 330i, and Z4! (bushing end only)
Why you should use TMS camber arms on your car:
Pros and cons of bushing deflection.
- Bushing deflection with a rubber material is good for absorbing vibrations and noises. This helps in maintaining the excellent ride/handling characteristics of the stock car.
- However bushing deflection is unwanted on a race or track vehicle because it leads to excess suspension movement. This is bad for handling, due to constant camber and toe changes. Plus, any power from the engine can take longer to get to the ground because it has to windup the bushing first.
Why is friction or force bad?
-
Any time you have friction or force from a bushing it will cause the suspension to react slowly, and that is not what you want.
-
How does this correlate to our 2 styles of bushings?
a. Bonded rubber bushings require more force to deflect the elastic rubber materials from their static state.
b. Spherical bearings with PTFE lining require the least amount of force because the spherical bearing has less surface area and the PTFE liner has a low coefficient of friction. Plus no extra force or friction is generated due to elimination of the high bearing misalignment design. This eliminates the performance-robbing characteristics of a rubber bushing.
Definition for Bearing Misalignment: Rigid bushings and bearings are often designed to work on a single axis and as long as loads are applied along that axis, all is good. When loads are applied to a bushing or bearing off its axis, increased friction or binding will occur. This off axis loading will cause bearing misalignment.
Note: Sold as a pair.
