New spec 3+ question grind (vette)
I installed my new spec 3 + clutch. Corvette install. It was a pretty straight forward install and I had the motor out at the time made it real easy. Here is my question I have a slight GRIND going into 1st gear from neutral. So I call spec tech line for some info on what the problem could be. He asked me how many miles and I tell him maybe 2 miles/new and then he tells me this is normal? And it will get better. I find it hard to believe this is normal.
Is this normal?
Am I hurting my tranny?
When will the grind go bye bye?

Mike, I am note sure who you spoke with (in truth it really doesn't matter) but I have a few questions and we can go from there. What flywheel is being used? Are you using new hydraulics? Let me know and I will be happy to assist you. Thanks,

The flywheel is a new spec flywheel steel billet. (clutch/flywheel packaged together sealed)
My hydrolics have on 10,000 miles on them and fuction perfectly. I flushed them out very well and also have a long bleeder line to make bleeding and fluid changes simple.
I did however install a new slave because of the work involved to get to the clutch/slave. My only concern with the install was I used blue loctite for the pressure plate on the clutch. Thanks for looking into this.

Im sort of having a small problem with this also. I had mine installed by a very reputable shop here that has done work for me in the past. My problem is that mine is kinda notchy going into second and it you dont put it into gear good enough, it pops out. This morning I was on the way to work and I actually grinded 3rd on a very gentle shift. I have NEVER ground a gear before today. Im thought it was me at first not paying attention... but now im wondering if its the clutch.
Im using a stock (turned) flywheel but I also had 2002+ hydraulics installed. What gives?

My guess is that maybe you guys should have an aftermarket master with the clutch, I have a MCLeod with my 3+ and it has work flawlessly for me and now that its broke in real good its almost like a stock clutch to me.

I just installed my Spec 3+ in my vette a few weeks back. Same problem, the engagment point was on the floor. Fortunately I have a Mcleod Master, so a few turns later it was up where I like it.

SPEC-01, Are you a spec tech? If I call spec tech line should I request to speak with you? Just curious what your relationship with SPEC is?

You may want to talk with Jeremy at Spec. He is Spec-01 and a good person to deal with. I had some issues that he helped me resolve and everything is up and going again!

I'd start out in 2nd gear a couple times to break in the clutch, you will be amazed at how much better the car will shift into 1st once the new clutch is broken in. The Spec Stage 3+ is about the only clutch we use, and once they are broken in, they work very well. Bob

Yes, I am a SPEC rep and I never said that grinding was normal. My response of breaking the unit in is related to the possibility that he has a disc that has a high edge. This is not common but it can happen. Should this be the case then miles will eliminate the problem. As I mentioned to Mike, an issue that affects one gear is unlikely clutch related...but providing the benefit of the doubt I still suggest completing the break-in process. He says that the issue has gotten better with miles (remember his can has less than 5 miles on it when we spoke). I am sure that he will post more info as miles are added. I hope this info helps. Let me know if you have any further questions.

As for Vette's in need of shims, Mikes pedal is not low, it sits mid-way up the travel. This alone is evidence that he does not need the shim. I know of 3 Corvette owners that need the shim in their cars and in each instance the pedal was evidently low (about a quarter inch off the floor). I hope this clarifies things. Let me know if you have any further questions. Thanks,
