I just wanted to post my situation I am having with SPEC clutches, www.specclutch.com
, regarding my SPEC stage 2 clutch kit and lightweight flywheel purchase.
The situation is as follows:
I purchased a SPEC stage 2 clutch kit and lightweight flywheel about 45 days ago. Last week, I finally got around to taking my car in to my local mechanic (a BMW only service shop that also services race teams)to have the clutch and flywheel installed. The clutch worked fine for the first 4 days; on day 5 my car became inoperable. It would not go into any gear. It felt as if the clutch was not disengaging. I would push the clutch pedal in and the car would grind its way into gear and feel as if it were 'lurching' forward at a stop with the pedal fully depressed.
I took the car back in to my mechanic to have them examine the situation. They double checked the slave cylinder, which was fine, and pulled the clutch out. Of the 6 allen bolts holding the pressure plate together, 5 had backed out! The mechanic told me that the kit itself was different that any other kit he had seen in a sense that SPEC uses flat washers rather than lock washers for these bolts. Even when properly torqued, the bolts backed out in a few days. There were no special instructions stating to use loctite or to deviate from the standard BMW clutch installation procedure.
I also enquired as to why SPEC uses SAE standard bolts and fasteners rather than metric applications on their European car parts.
So I send an email to SPEC explaining my situation, requesting a reimbursement for $255 in discounted labor for the second install and this is the email I receive from David Norton at SPEC:
There is obviously no defect in the manufacturing of the kit. Pardon my haste, but any mechanic should understand that when lock washers are not used that loctite is a must, and loctite is recommended on race applications even when lock washers are used.
Secondly, lock washers are included in all our BMW kits-the shop just didn't use them. Hypothetically, if by some rare case the washers were left out why did the mechanic compromise your safety by not installing washers (or calling us to send him some) and deliberately not use loctite? There is no excuse.
Thirdly, there is no way the bolts backed off in 4 days if they were
correctly torqued in the beginning. And lastly, those are 10.9 grade premium race fasteners (the same ones we use in Grand Am Cup racing on the BMW's. (BMW fasteners are grade 8-). There are also helicoil inserts installed in the fastener holes, as well. Why do you think they are not good enough for your 540 and why do you think they should be metric? Your kit carries SFI certification and is rpm tested
to 14,000 for the ultimate in safety and performance. No BMW street/track kit on the market carries that level of safety. It is, however, imperative that a competent individual install the products properly. Maybe it's a great shop, but the mechanic didn't have his grape juice that morning.?? I know it's hard to say, but we did our job with the product. The product cannot be defective due to the install.
Anyway, my suggestion is to stay away from companies that are unwilling to help and that give inappropriate advise.
