Suspension Noise with Pillowball Style Uppermount?

Due to the design of aftermarket coilover systems like the Revel Touring Sports Damper, coilovers on vehicles with McPherson type struts will have metal pillowball bearing upper mounts and may introduce some noise during driving because there is now metal on metal contact (OEM suspensions use rubber mounts to supress these noises). However, if there are loud noises occurring (like a binding noise), double check the top lock nut and make sure that all other hardware is tightened as something may be loose. Also check that the spring preload is set correctly (we recommend preload to be set from 0mm-15mm).
