Default Help on C5 Rotor Upgrade

Alright, I want to run the larger C5 rotors on my 2000 T/A and I know I need a relocation bracket to keep my stock LS1 calipers. However, UMI's conversion kit will not work with 17'' Torq Thrust wheels and would require modification of the spindle if they would fit my rims.

My question is, is there a relocation/conversion kit/bracket that will work with my 17'' TT M's and that does not require cutting my spindle?

Thanks

cutting the spindle is cake. I know you didnt ask for that but its pretty simple. i see the concern if it doesnt fit your wheels though.

If you want to run those brake and those wheels, you will need to run a spacer so that the spokes will clear the calipers. No other option really.

8mm wheel spacer+ARP wheel studs = problem solved. Or a new set of rims....

Are the C5 brake pads larger than stock LS1?

They are roughly the same size as the LS1 pads, maybe just a tad larger, but its nothing that will make any difference.

Pad size generally does not = brake torque. Larger pads however help the pad to run cooler when you are beating on them.

The C5 calipers though are stiffer due to being vacuum cast and and their strengthening ribs. They also have slightly smaller pistons than the LS1 calipers.

Thought I saw a set that 6LE makes and they don't require ANY modification to the spindles (unless you're an LT1).

The pads ARE bigger and they DO make a noticable difference. Just did the swap myself.

Pad size generally does not create more brake torque. Pad compound on the other hand does, as well as the extra torque created by the larger diameter of the rotor.

Larger pad usually means cooler pad, given the compound is identical.

I can get a set of c5 calipers and rotors and brake booster for 250.
I have a set of LS1 spindles, would the only other thing i need be the brackets?
Is there a difference between the c5 and the c5z06 brakes?

You do NOT need to cut the spindles with our brackets...

No difference in actual caliper design.

The Base C6 caliper however is stiffer than the C5 stuff.

So, if I run an 8mm spacer on my 17'' TT M's I would be able to fit larger calipers and rotors?

If the pad size was the same the larger rotor wouldn't make a difference...

^^Actually larger rotors with the same pad make a big difference. Braking is like a lever and you just made the lever longer with the larger rotors pushing the caliber out.

Further on on the lever the same work will now exert more force.

So is the CTS-V caliper larger than the C5 caliper?
I'm starting to drift towards C5 rotors with brembo calipers.
I know the CTS-V is a brembo make however I think the CTS-V rotors are larger and therefore the calipers would be larger and would not be usable on C5 rotors.
