14" Wilwood front and rear DONE!
I have had this done for a while, but have been too busy buying a house and moving to get pictures up of it.
I did down grade from the 15" custom Wilwood front and rear kit that was on the car, but that kit is destined for bigger and better things...Protouring 69 Camaro.
Now back on topic;
The front is just the standard 13" Wilwood kit with the BSL6 that I replaced the rotor with a 14"x1.1 rotor and designed a new main bracket to move the caliper out .60".
The rear was a complete kit purchased from HotrodsUSA.com, I said the name because I don't think any of the sponsors offer a 14" rear kit. It was right around $2k for the complete kit with the BSL4.
They are behind 19 and 20 inch wheels, so they do fill out the wheel fairly well but not as good as the 15" brake kit did!
Sorry I do not know how to load pics, but they are in my album...

I mainly did 14's to fill the wheels better. There really isn't going to be much gained over a 13" kit. I haven't been able to really hit the brakes hard for a sustained amount of time to compare to the 15" kit. All I know right now is the limiting factor is the tires sticking to the road during hard braking. I think the only difference will come in any bit of brake fade since my 15" kit has more volume to the rotors to dissipate heat, but I think the 14" kit will perform better than I need.
The braking improvement is LEAPS and BOUNDS better than the stock LT1 brakes, I was seeing brake fade after about 2-3 hard stops.
14's are supposed to be able to fit on 18's, but it still depends on the wheel. The only way to know for sure is to go to wilwoods site and look up the kit .pdf and find the measurements to make a template to check clearance (you would just have to adjust the template for a 14" rotor instead of the 12.9" or 13".

wow, crazy big for the rears, but looks like nice work.
Not sure about your install specifics, but I would definitely make sure you have proportioned the brakes properly with a proportioning valve. You don't want the rears locking up in a panic situation - it could cause your car to spin out.

The kit does have a proportioning valve where the ABS used to be (it has since been eliminated).
I used Wilwood because I already had the front kit and used brake kits are pretty much worthless. I used Wilwoods on the 15" kit because I didn't research enough. I would actually recommend using a factory calipers for custom brake kits. The C6Z06 calipers look to be really nice calipers and VERY cheap, and the new Caddy CTS-V calipers are actually Brembos and may be reasonably priced once available from GM. If I had both kits to do over I would be using the C6Z06 or the new CTS-V calipers, Coleman Rotors, Wilwood hats, and Wilwood Parking Brake Assembly.
Buying a complete Brembo kit is EXTREMELY expensive...

Wilwood part numbers...
249-9776/77-Bracket Kit (pair, one each, left and right), E-Brake assembly
250-7549-Retainer, Bearing
170-9493-Rear Iron Hat (for internal parking brake), 5 x 4.50/4.75/5.00, 1.95 offset, 12 x 8.75 Bolt Circle
170-6837-Front Aluminum Hat, 5x4.75, .88" offset, 12x8.75 Bolt Circle
Coleman...
15" rotors (can be ordered with 12x8.75 bolt pattern machined in it)
http://www.colemanracing.com/catalog...p?cPath=28_470
14" rotors (can be ordered with 12x8.75 bolt pattern machined in it)
$175.15 each (email Coleman for more information)
Calipers...
Yes the 2009 CTS-V are the LARGE 6-piston Brembo calipers, the 04-07 are the smaller 4-piston Brembos. I don't have any information on them or pads
Mounts...
You'd have to design the mounts yourself or have a custom shop do it, if you cannot do it yourself this kit could get VERY expensive. They are very easy to design once you have all the mounting dimensions, but since I don't have any of the caliper info I cannot help.
Misc...
1/4-28 aircraft grade bolts with locking wire holes in the heads to assemble the hats/rotors
Other misc bolts to mount calipers
When I priced all of this out using C6Z06 calipers it was around $2500 for a complete 14" kit front and rear.

dude, you are a WEALTH of information.
I don't need any new brakes but for what it's worth, your're a giver.

The black circle in the center of the rotor is the hat. It mounts to the rotor and there are different offsets to set the rotor deeper or more shallow against the hub face.
