What is the difference other than looks between the C5 Zo6 and LS1 brakes to my knowledge they are both dual piston?

Bigger rotor
Better casting (pressure vs. gravity cast)
Full-width stiffening ribs across the back
Smaller piston diameter

I'm assuming you are only asking about the fronts since you mention the dual piston thing.

C5 LS1 or Fbody LS1?

They are stiffer, cast better, utilize a 1" larger diameter rotor, etc. etc.

They are an upgrade for sure, how good of an upgrade really depends on what you use your car for.

All C5 had the same brake hardware, the only difference between them all were cosmetic (the Z06's being powdercoated red). The corvette brakes compared to 98-02 fbody brakes are pretty similar, but as mentioned above the corvette ones run a 13" rotor and the fbody's run a 12" rotor. The vette brakes are also built better and many claim (and are probably correct) that they are more durable then the fbody brakes, also mentioned above.

C5 Brakes are a great, cost effective, great bang for the buck upgrade-especially for those with 17" wheels-they fit perfect in most. You can piece together a kit on your own for about $500-$600 if you look hard enough, or buy the whole kit outright from UMI for $700+ depending on options.

Do you have an fbody now? LS1 or LT1? Or are you looking at the difference between the C5 and C5 Z06 brakes?

Technically the F-body runs an 11.8" rotor and the C5 (non-Z-51 package) runs an 12.8" rotor..

Not correcting to bust your ***** or be a dick, but just trying to get the most accurate info out there.

This is true, and if I'm not mistaken, the Z51 package uses a 13.4" rotor.

I've seen the Z51 listed as 13.1 and 13.4. I wonder which one it really is? Also what years?

The pistons in the Fbody LS1 calipers are bigger than the corvette.
This would put slightly more braking emphasis on the rear when using Vette calipers on an F body.

I wanted to compare fbody LS1 to C5 Zo6, wondering b/c with the rebate going on now @ SSBC you can get 4piston caliper setup for under $1000 V.S. $600-$800 for C5 stuff

While I am always one of the first ones to tell someone to go with a fixed 4 pot setup over a floating 2 pot caliper, I am hesitant recommend the SSBC 4 pots over the C5 stuff.

Im not saying its bad or not, all Im saying is that the SSBC 4 piston setups have not really been tested out on the track from what I can find. The C5 setup however has proven itself over the years, granted with its own issues (caliper spread being the main issue).

What are you going to use the car for 90% of the time? Will it see Track day duty? Can you find people that have run the SSBC Extreme 4 piston setup? What do they have to say about it?

These are questions that I feel should be answered before buying them. Just because they have 4 pistons, does not necessarily make them better.

C5/LS1 setups both work pretty well, the difference being the C5 setup holds up better under tracking, plus has a leverage advantage from the larger rotor and improved cooling (from the rotor size and directional vanes). Stopping distances are pretty similar between the two, so if it's a street car and won't see hard tracking, I guess I'd just go for whatever's cheaper (unless you want the bigger rotors to fill out wheels better).

With the slop in the F-Car front hub design and the lateral movement of the C-Clip rear axles, a fixed position caliper would almost require a floating rotor.

If you don;t, you'll see tons of pad knock-back.

FWIW ... a C5 caliper is a direct bolt-on replacement for the F-Car caliper. Use the F-Car pads, abutment bracket and rotor ... no issues.

I agree with you Mitch in regards to the c-clip rears causing pad knock back with a fixed caliper, but I don't necessarily agree with you about the fronts.

Granted, the hub design is pretty craptastic, but if they are at least somewhat fresh, there usually isn't any play, at least not enough to cause any knock back issues.

My current hubs have around 10k street miles and maybe 300 track miles and still don't provide enough play to cause any issues with my Wilwoods.

Can you use corvette brackets with stock ls1 caliper? Will this fit the stock front rims on the z28?

ROCNDAV

iTrader: (100)

Yes, this is what I am currently doing.

You do need to get Vette pads. The Camaro pads are too wide and will start digging in to the outer edge of the rotor. Ask me how I know

I like my C5 Z06 calipers. I'm using Fbody rotors and pads with them right now. For the street they work just fine, i'm sure something like a CTSV brake kit or C6 brake kit would blow away the C5 stuff, but for the price I think they are worth being considered. When I went from LS1 to C5 brake calipers it seemed like the pedal felt better and was more consistent. Maybe it was all in my head but it did seem much better especially during high speed stops (100+ mph). Plus the calipers have a much better look to them as opposed to the LS1 calipers. I get compliments on having Vette brakes all the time, if your one of those people that like getting compliments and like the extra attention that may justify the cost by itself.
