Good info, but that pic with the formula wheels is NOT acceptable clearance to me. I wouldn't feel safe If I had to "look" for a gap to see the light coming through. Id feel much more comfortable with the 13.5" Z51 rotor. I know alot of you have seen this, but if you havn't, heres the combo with the Z51 spec rotor in a 17inch wheel using a 3ed gen spindle and conversion bracket by EBMiller:
More info though: Alfa Romeo spec 4 pot brembos DO have 130mm between mounting points, so they will bolt on. I don't know offsets, and I don't know how much away from the center of the hub they sit, but they seem to have shorter mounting extentions than the caddy caliper. These are not the same size as the caddy or evo spec calipers. These are smaller...
Heres a pic for reference:
This is a good starting point for a smaller kit, but I'd want larger calipers if Im going to make my own kit. The problem I run into whith my wheels, is that they have 15" centers bolted to a 17" wheel hub, so there is a large "hill" going from the centers to the hub on the inside of the wheel. I really don't see how I could fit the Caddys because of this.
Oh, and for anyone wondering, I lost the auction for the Evo calipers!

real good info here man,, those alfa calipers look perfect, as long as there 4 piston i think they will be good, im going to either look for some evo calipers or the alfa calipers, since im pretty sure i can make a bracket for it in my garage or i can try drillng some rotors. does anybody know if the f body lines or which brake lines would connect to ours?

Not sure on the brake lines, though I know people have done conversions like this, so there must be a way. You and I have to worry about spoke clearance with setups like this though. i wouldn't be surprised If im going to have to run a 1/2 inch spacer...

^^ yea i know about the spoke clearance, i wouldent want to move the wheels any more further back unless i realllyyy have to. i think the evo calipers would be real good to work with. did u say i can use the 13.4 Z51 rotors under my 17's? i want to be 100% sure b4 i buy the evo calipers, i would not want to run into a simple problem like the rotor is to thin and the calipers pistons come out too far.

Spacers that thick add a lot of stress to the studs. Some folks say it's too dangerous. I don't really know myself. You can get adaptors as thin as 3/4". Those bolt to the hub then the tire bolts to them. These are very safe to run.

I'm curious about the 15.5" rotors on the new ZR1. I'm also running 19x10's like the ZR1.
The car's braking system features carbon-ceramic rotors measuring 15.5 inches up front and 15 inches at the rear. GM says the rotors are so durable they should not requiring replacement for the life of the vehicle.

Those rotors would be cool to use, but they would cost ALOT. They come standard on some very exotic cars...
Just thinking outloud, you might be able to use a C5 conversion kit and the CTS-V calipers to clear the 15.5s.

Im fairly sure their rear ZR1 rotors are the same spec as Ferrari Enzo front rotors (No, I didn't make a mistake typing that) , so the fronts are most likely made by the same supplyer. Ill see if I can find more info.
Edit: found this quote
"In what must be a very sweet moment for a longtime Corvette engineer, Juechter notes that the monster 15-inch Brembo carbon-ceramic rotors fitted as standard to the ZR1's rear wheels are the brakes originally designed for the front of Ferrari's 650-hp Enzo supercar. In the front of the ZR1, you'll find even larger 15.5-inch carbon-ceramic units.
Juechter says, "The only vehicle I know of that has these brakes as standard equipment is the 1,000-hp Bugatti Veyron." Then he adds with a grin, "Although I think you can get them as a $20,000 option on the Ferrari 599." We get the sense Juechter will be using these laugh lines many, many times in the near future."

Even if the 15" rotor does work, it still kills the whole point of a cheap big break kit...minimum 19" wheels.

Yes and they work great. Those of us with thirdgens that had upgraded to LS1 brakes are now easily upgrading to the 14" CTS-V setup. No spoke clearance issues (front wheels have a goofy offset).

I'm curious to see the cost of the CTS-V calipers to use on a custom 15" brake setup on my 69 Camaro. If they are even close to the price of the C6 Z06 calipers ($500 for a set) I'll be using them.
I actually found a REALLY good solution to a Parking Brake if you do a 14-15" rear kit. You can buy the rear Wilwood cast iron hat and internal parking brake assembly for about $350 for both sides, then you would have to buy rotors with the correct bolt pattern to use them (Coleman will machine any bolt pattern into their Rotors for you).

Maybe when the ZR1 comes out and we can get our hands on the 15.5" front rotor....

Now the Porsche GT3 has a 2 piece 15" rotor from factory...I wonder if they could be acquired cheaper than a custom 2 piece. If the hat height will work that is.
stole this from a porsche board

CTSV = $340
Z06 = $700+ with pads plus the Z06 padlets are fairly thin and wear unevenly.
I think it was $167 each for the front with pads and clips.

No I am talking about the 2009 CTS-V calipers. They are the same ones as the ZR-1 (the huge 6 Piston Brembos)
http://www.autoblog.com/photos/detro...-cts-v/556406/
"Like the ZR1, six-pot Brembo calipers do the work up front with four-piston units at the back. In this case, though, the 15-inch front and 14.7-inch rear composite rotors are made of steel with aluminum hubs and slotted surfaces instead of carbon ceramic"
