More on Control Arm Bushings
For the benefit of all here's the physics behind the newly introduced product from SRD:<p>When cornering, loads will cause latera; deformation to the weakest part in the system. If you were to run 80 series sidewall tires, the tires would be the weakest link and would take most of the suspension lateral deflection. But since most of you guys run 40-45-50 series tires with relatively stiff sidewalls, the OEM rubber control arm bushings are highly solicited and their deformation causes the wheel alignement to change to an non-optimum level during hard cornering. In oder word your tires loose some grip because of a reduced contact patch with the ground. You could can gain up to +0.75 deg of camber (Mazda specs are -0.5 +/-0.5) which means you can even run in positive camber in corners. Bad for performance, bad for tire wear. <p>Another nice key feature is that steering response is increased as the tire/control arm assembly doesn't need to wait for a bushing to compress before taking the full load. In other words you wheels are more directly connected to your steering when cornering.<p>Please feel free to contact me at luc@srdperformance.com if you need more info in this product.
