Bolt size for C5 brake adapter plates?
My friend and I are about to upgrade his 91 ZR-1 brakes to C5 calipers, rotors, etc. He purchased some used calipers and caliper brackets which are now clean and ready to install. He also got some new adapter brackets, but they did not come with hardware. My question, then, is what size bolt do we get to hold the adapters to the spindles? It looks like the adapters are drilled and tapped for M14X2.0x?? Yup, we don't know the length. From pictures I've seen, these bolts are usually allen head and grade 10.9. Before I go to the friendly nut, screw and bolt store in our area, however, I need to know how long should the bolts be that I ask for. Please help if you know. Thanks.

Try these install instructions with "snap-shots"!! There are a couple of different style adapters out there I believe so you need to make sure yours are very similar to these. Good luck! There's nothing that says "these are what you need"! Last edited by WVZR-1; 07-28-2012 at 09:27 PM. |

Dave,
Do the C6Z calipers use the same adapters as the C5? I'm thinking of selling my Brembos and going w the Z brakes/rotors.

I think there's some C4 folks on the other forum who have discussed the CTS-V swap. I don't recall specifics.

Can you do the C5 upgrade with the stock rims on my 90?

Re: Bolt size for C5 brake adapter plates?
I don't think that the '90 or '91-'93 wheels will clear the calipers. The a-molds provide adequate clearance, however.
