So I just recently installed the ACT clutch, ACT flywheel, Wilwood clutch master cylinder, new clutch slave cylinder, and properly bled it out with motul high temp clutch fluid. I knew that once I installed all the parts that the clutch would have a chattering sound just like ACT said there would be. Now the problem that I am having is that when I turn on my car and start to go there is a very loud sound, and the car almost starts to jump a bit (Even when I give it more than enough gas). But when I start the car and turn of the VDC (Vehicle Dynamic Control) the car does not make the weird noise and also does not jump. So my question to you is what's the problem? Should I bypass the VDC to permanently keep it off, or is there a possibility it could be another problem.

 

when I installed an ACT six years ago...it had the wrong flywheel. SHop said something about the teeth not being correct. Cost me an extra grand to correct as I had purchased it from a diff shop.

I have no clue about your symptoms but thought I's share just in case.

good luck

 

Did the car still drive with the wrong flywheel? And did it have any symptoms mine does?

 

couldn't tell you...shop installed then troubleshooted before calling me.

something to check though....if flywheel teeth looked the some as old one.
