You too, have a PM.

I've heard of the big brake swap using the 1LE f-body 12" rotor but it uses the same spindle and upper a-arm. The C5 upgrade you cut the caliper mounting ears off and use the adapter bracket. You then remove the brake surface of a B, F, or G-body rotor which has the bearings in it and use it as a hub. Mount the hub as you would any front disc and that will allow the Vette rotor to be mounted. You then mount the caliper assemby to the bracket. WaLa ... You now have C5 13" brakes!

I've never dealt with Robert Adams but I know several people who did. Were you ever on the Monte-List.nu mailing list? If you know Robert, I bet you were.

i didn't know the C5 upgrade uses the b-body spindle. maybe some day in the distant future i could upgrade to C5 stuff by only changing the caliper and rotor.

Yeah, you sure can. And it'll be as good as "brand *B*" setups. Depending on where you get your parts, you can figure it 2 ways. You can have C5 front brakes AND the LS1 rear disc brakes for the same cost as what they want for just the fronts or you can have the fronts for half (maybe less) than theirs.

Now I were are starting to date myself against the timeline of internet based information exchange. Yes, I was on "the Monte List" for many many many years and got into many many many memorable exchanges of opinion with it's membership.

Lots of good memories from those days. Even made a few long term friends out of the deal.

Keep us posted on this build, Doug.

Doug,

I have the B-body set up already; my kit was put together by Robert Adams years ago. I like it, but there is an upgrade coming to the rear and I want the front to match.

This C5/B-body setup sounds like the same process as the LS1 brakes onto the stock spindles.

You have a PM.

Thanks!

The LS1 calipers & the C5 calipers are basically the same, some extra cooling fins on the C5s, not sure if piston size is the same or not. The main difference between the assemblies is the carrier bracket for the caliper that mounts to the spindle/knucke is shorter on (I think) the LS1 calipers than it is on the C5 calipers.
