Fidanza clutch bolts.
Just wondering what everyone is using for clutch bolts when upgrading to the fidanza flywheel. I remember seeing some bolts with more thread engagement somewhere. Is it necessary?

Here's the link on where to get them. Just any old bolt that's longer is not good enough. There is a counterbore in the flywheel, sized to allow the shank of the bolt to sink below the face of the flywheel, reducing radial clearance and thereby preventing the bolts from moving. Use these bolts! They have been properly engineered for the job. I've used them. http://www.zr1products.com/products.html Ron Woods is an engineer, a first class ZR-1 driver and knows his stuff.

Re: Fidanza clutch bolts.
I agree they are the way to go. The stock bolts thread engagement is minimal. I think 100 for 6 bolts is a little bit steep. Are they custom made or has he found an ARP bolt that fits this application? Im running a different pressure plate since Im using a T56. I wouldnt want to shell out 100 and find they dont work. Maybe I can give him a call. I found that three packages of torque converter bolts from ARP is what works for the flywheel to crank. If anyone would like the part number I can dig it up. Thanks for the help!

Re: Fidanza clutch bolts.
Ron had the bolts custom made for him from ARP. Pkg also includes drill bit and tap. Bit & tap don't add much value, but I'm sure having the bolts custom made wasn't cheap. I didn't want to drop $100 either, but it was the wise choice in my opinion considering the possibilities. I'm old school and saw several clutch & flywheel explosions in the "old days."
Give Ron a call. He's more than glad to talk with you and share his knowledge. I found the TQ Converter bolts too @ ARP and used them. I think they come in pkg of 3 or 6, cant remember for sure, but don't forget that you need 8 for the LT5. I tend to get a little carried away sometimes, but a lot of folks use thread lock compound, but forget to clean & prime the bolt & tapped threads properly. Should use cleaner/primer made for thread lock compounds, otherwise the job is compromised. Opps! Sorry for the rant. Saw you are tool & die guy. I used to own a machine shop many yrs ago. You're an expert on this stuff.

Re: Fidanza clutch bolts.
Good advice. I will give Ron a call next week. No apologies necessary, too much info is never a bad thing!

Re: Fidanza clutch bolts.
I just checked the catalogue. There are two applications with a 7/16 -20 bolt. I will have to see which ones I used. I will post it as soon as I can get out to the shop.

Re: Fidanza clutch bolts.
I used Rons bolt kit too. See pics of the difference in bolt length at this link.
