Well my experience is hell!! Just installed the Spec clutch set up, and we were getting a very loud and high pitched slipping noise from the clutch when leaving from a start in 1st and then in 2nd gear. We were originally told that we did not need to install the additioanl flywheel, since we were not going with a wild set up, just a very mild one since we did not race or trake the car at all. When we called up their customer service, their tech support, they actually told my mechanic to tell me, "to up my radio, so I couldn't hear it!" Well after he picked himself up off the floor, he called back to speak with someone else and they offered no solutions. This went on for about 3 weeks, until we got a hold of someone in their tech department that sounded older than 20 years old, and had some obvious knowledge about there product. He said that we indeed needed the flywheel, and that the person who placed the order should've know this. After we order the flywheel and installed it, the noise did go away, but know the clutch slips in any gear, when you mildly step on the gas. Under very modest acceleration, I go through all 5 gears and max out at just above 75 mph, never going below 5k rpms, when we used to be over 100 mph in 3rd under the same acceleration. When we called up this time, they told us they would not help us, because the clutch was over it's 30 day wty, and considered used, even though it was their own techs for the reason the 30 day wty ended in the first place. So, I would tell anyone that would listen, stay away from this product!!! More for their lack of customer service and focus after you puchase the product, and secondly becuse they will not only stand behind their products, but there own employees do not even know about their products...
Spec Clutch: $400 + Labor
Spec Flywheel: $400 + Labor
Getting everything fixed for the 3rd time: Still Waiting for that Bill
Spec's Tech's Answer: "turn up the radio, so you customer can't hear the noise" = PRICELESS PS, I have the Shaker 1000 set up, and I can still hear the noise!!!
