... yes, it is a 'floating' caliper. This kit comes with the slide pins and all the hardware.

Yes its still a floating caliper. Same mounting as the LS1 Fbody brakes but with a larger rotor. The caliper is VERY similar but is pressure cast and therefore stronger. Plus its powder coated so its prettier too

Ken-
thanks for typing out something that i am far too lazy to do


keith-
First of all, unless you aren't pushing very hard, I cant see how you can lock up your front tires with 315 hoosiers lap after lap (or on a long/fast autoX course). The only time my LT1 brakes even came CLOSE to being adequite was when i had a full on race pad, and they still were ok.

but lets just say you only autoX, and can lock up the tires(slow/small course). As Ken stated you want to be JUST ON THE VERGE of lock up, as that provides the fastest negative acceleration(hey, since he gets to talk physics.. so do i). A better braking system will make it easier and more consistant to be on that edge.

On our last autoX course my GFs brakes (stock LT1 brakes+PF Z-rated pads) were TOAST. I couldn't stop at the end of the run(this was on a fast, 80mph 80second course). my car with a baer track kit(not a great upgrade, but not bad) with the same pads showed half the fade(although they did fade).

note that my GFs brake did not fade on her. However, I am ~top time of day, and she is a few seconds back. those few seconds on a 80sec+ course are the difference between the brakes being ok, and not.

Well, I don't have 315 Hoosiers...

...and I have LS1 calipers...

Whether or not I am pushing it is in the eye of the beholder, I suppose. I CAN say that after a 20 minute session on the track, if I stand next to the front of the car, the heat will radiate through my pant leg to the point that I have to move to avoid being burned...

If you are "toasting" your brakes (regardless of what calipers you have) in autocrosses, you really need to think about your choices in pads and/or brake fluid. The problem here is not the braking system - it is the expendables put on it... Try a better pad and see if you get fade with either setup...

Anybody ever thought of a dual caliper setup for the fronts? You get much more pad surface on the rotor. Just because you are locking up the brakes doesn't mean you are using all of your available grip during braking. You can stop the rotor with two 3/8" round pads and lock up the wheels.

I mean it just makes sense to design a relatively cheap dual caliper system, whether it be with a floating caliper like the C5 design, which isn't bad at all and is a huge improvement over the stock F-body design. Or perhaps a high dollar model with twin fixed calipers. Either way, more pad area = less heat transfer to the rotors/brake fluid, and with our nose heavy cars it could be a blessing.

I guess its a matter of finding room and a rigid bracket design within the spindle.

Jordon, I can lock up my LT1 brakes (Hawk Plus pads) with my 315 Hoosiers.

brakes

I was just going to say I have run into a guy that had 2 sets of calipers on the rear of his car but on the front he used a big 6 piston kit. He had a zr1 vette that was used just for road racing and the motor produces 550 ponies. He said the car stops much better with the 2 sets of single piston kits and it also allowed hit to be able to adjust the brakes in the rear of the car. But the down side was the additional unsprung weight that was being added from the second set of calipers.

I just happened to find a guy on e-bay selling a corvette 4 piston pro + Baer kit that had been on the car a couple thousand miles. He sold his z06 and he took the brakes off and he was asking 1500$. So all in all I think I will be quite pleased once I get it all paid off.

I was thinking about the Z06 brake upgrade kit but I figure that kit was not really adjustable in terms of rotor size and I wanted to be able to upgrade to a larger 14 inch rotor later down the road once I find some 18 inch wheels that will match a 30th ann with hugger orange stripes. If you have any suggestions I am all ears.
