CTS-V Swap and No Track Use? Why?

CTS-V Swap and No Track Use? Why? I was looking through jasonWW posts on the CTS-V calipers and Z06 Rotors, why can't we use these on the track?
I figured a brembo setup with bigger rotors would work better for the track...
Is it because we have to use those washers to space the caliper out?
My concern with doing this brake swap is if i am going 150+ and i need to stop, will these things hold up better or worse than my stock rotors and HPS pads?
Lastly, a while back i saw a post of a guy with 10 spokes like mine that put a bigger brake kit on his car. He used a 1 inch spacer. Anyone know this thread?

The c6 Z06 utilizes a drilled rotor.
Notice the holes are drilled in a directional pattern.
Many of the Z0 guys who ran their cars on the road courses where expressing issues with the stock rotors as there is only one rotor which is used on both sides (therfore one is "backwards")

I dont run the Z0 rotors so keep in mind this is all heresay.

People often question it, but it has never been documented as an actual problem.

A buddy of mine races at spring mountain, he drove one of the C6Zs and he cracked the rotors...
not sure if it matters.
I do notice the holes drilled in a directional form, can you just run a blank or a different rotor and solve the issue?

Run a blank, I have never seen a drilled rotors, thats been subjected to track use not crack, your gonna get some minor cracks, that dont really matter they can be turned out, its the big ones that are an issue. Seen pics of it on Porsche stuff and on high end brembo stuff.
When I was in my brake seminar, they were telling me about a few guys who are buying up cheap Autozone white box rotors, takin them home and putting them on a drill press then selling them on ebay as "high performance" drilled rotors. Apparently they drill right through the vanes and everythign which seriously compromises integrity, but for the most part good reputable brands dont do that. Just a little tid bit for anyone buying rotors off ebay, do some research.

look on corvetteforum and do a search in the autocross/road race section...there are facts
also, the ZO6 calipers use individual padlets as they are called rather than 1 pad per/caliper. This also raises heat and hurts stopping power and performance. Carbotech makes a pad to solve that issue and fits normal so instead of the multiple padlets it is 1 single pad per caliper..greatly reduces heat and helps stopping power. The C6Z guys who track there cars regularly change there brake setup pretty quickly to a stoptech or brembo setup

The deficiencies of that brake system only become apparent with serious track use.

and I'm not arguing, if you're talking about street use. On the track (road course), you need everything you can to get the car stopped as late/fast as possible.
because there's not a lot of rotor surface area. Larger rotor = better cooling is allowed through the system. a 6 pot setup on that size rotor could generate a lot of unwanted heat in the brake system....though a lot of people use that wilwood setup with no ill effects on track.

that will come down more to the pad you run and how cool you can keep your brake setup. Good set of spindle/ducts from Quantum Motorsports + a good set of Hawk or Carbotech type pads (there are others like Cobalt, these are just the main ones). Obviously a better than stock caliper/rotor setup would help too, but it is not needed. There are plenty of people racing their cars on track with stock calipers

Both the CTS-V/Z06 and Z06/Z06 upgrade will be more than sufficient for that kind of demand, even with stock pads and without brake ducts. Now if you're going to do that repeatedly, then you're going to need better cooling, such as ducts.

I hope you understand that your braking efficiency depends alot on the tires. The stickier the tire the less your brake distances become.
In other words even if you have a 6 piston setup with 14" rotors and upgraded pads, without grip your not stopping.
What I'm trying to say is that if you aren't going to track the car, a C5/ C6 caliper with a 13 rotor and correct pad will do you fine, as long as you have a decent tire up front.
Otherwise you might just simply induce tire lock up and of course the ABS system.
Also, brake ducts are for tracking and or lapping a car, same thing for race compound pads.
Running ducts and race pads on the street is not recommended. You will over cool the rotors and the pads wont get up to operating temps. Race pads need a certain amount of heat to induce the bite and ducts help the rotors survive.
