SPF owners- check your rear axle CV joints !!! Jack the rear of the car off the ground, trans in nuetral and park brake off. Rotate the rear wheel(one at a time) forward and rearward while watching the axle shaft end that is stubed into the differential. If you notice any slop you need to carefully peel back the CV boot(s) and take a close look for damaged bearings. SPF had a supply problem and had installed used(rebiult) axles/CV joints. This happend to my car at around 600 miles. I noticed a clunk powering out of a righthand turn and then a slight vibration at higher speeds. Also check for CV joint grease being flung out radially from the boot! This was warrentied for me by Superformance!! The only thing I don't know is if both axles on my car were rebiulds? I was told that there were about 100 rebiult assemblies in ciculation.
