Yet another C5 brake upgrade in progress

Just wanted to thank all the ThirdGen board members, especially Ed Miller for figuring this out and inspiring my low buck brake upgrade.

Re: Yet another C5 brake upgrade in progress

I'm sure you'll enjoy them. I can't take credit for the C5 stuff, there's many others to thank before you get to me. I just took the ball and ran with it. I'm still running so to speak, in many different directions.

Good luck!

Ed

Re: Yet another C5 brake upgrade in progress

After that effort, had to shoot some paint on it. No calipers yet, but the rotor appears to be centered in the caliper bracket with about the same gap radially to the outer diameter.

Re: Yet another C5 brake upgrade in progress

So What all has to be done to Convert from Drum to Disc in rear? Just get the Plates, Backing plates, Rotor and Calipers, and put the screws where they go, and the Lines where they go? Sorry if i'm mistaken...

Re: Yet another C5 brake upgrade in progress

If you don't need an e-brake, C5 could be that simple. I cheated and ordered a 4th Gen spec Moser 12-bolt and swapped in the LT1 rear brakes from my donor car. The LS1 rear disc conversion requires a little cutting and drilling to the drum flange. Doesn't look too hard at all. Hand tools.

Re: Yet another C5 brake upgrade in progress

dose anyone make a C5 spindle/hubs to backspace Z06 rims properly without spacers?
currently I have 2.1/4" SPD adapters and im worried about strength with my C5 upgrade.

Re: Yet another C5 brake upgrade in progress

I've not seen that in my research. On the plus side you will need smaller spacers with normal converted thirdgen hubs.

Re: Yet another C5 brake upgrade in progress

Though none of them are DOT approved, I have never heard of one breaking. I'm running a spidertrax set on my Jeep along with a lot of other people. These see quite a bit of abuse and the failure has always been something else.
