there has been talk of this in another thread and I have sold the calipers to a couple of folks already. the slight problem has been rotor fitment however. well I appear to have a solution in the works for that. should have a larger 2 piece rotor for the 04-07 V in about a month. the whole "kit" (rotors, calipers, and hardware) will be aproximately $1790.00 with the new rotors making up $895.00 of that. with all of that said I need 6-7 people to be very interested and call me with a firm commitment. I won't bill anything until the product arrives but need some credit card #'s to make me feel better about spending MR. Lindsays money.
please call 703-647-8670. don't have any pictures yet of the new rotor but THEY WILL BE VERY SIMILAR TO THIS ONE. probably a black hat instead of blue and will not be a floating rotor like the pictured one is (still 2 piece though)

1) Would this kit be using the CTS-V2's 15" front rotors with the awesome 6-piston calipers?
2) Does this kit just cover the fronts?
3) Do you have a two-piece solution for the rears as well (in the stock 14.4" size and still being able to use the parking brake), knowing that UUC was not making those rotors for our cars any more?

We will also need good pads for the new fronts (something other than factory GM pads) and new stainless steel brake lines for the front calipers as the 6-pots have a different fitting than our stock ones.

Once these questions are answered (and if this will allow us to use the big V2 front calipers with 15" 2-piece front rotors, get new ss lines, and get some 2-piece rear rotors as well --> I assume the rear rotors would be extra $$$ which is fine!), I would be in for sure!

This is what Racing Brake was attempting to do (for a bit more money), but we haven't gathered enough interest for them to start making the 6 lug rotor hats, 15" rotors, and mounting hardware for the 6-pot calipers.

1)the above price includes the awesome V2 6 piston calipers
2)this is just the fronts
3) I have asked UUC about a rear 2 piece and they are going to start looking at it next week
4)I currently carry Hawk HPS or HP+ along with stock for the V2. I am looking at performance friction as well.
5)brake lines are an easy fix. thats in the works as well. worse case (and if folks dont want braided lines) the V2 stock lines will work from the V2 caliper to the V1 bits.

The owner of UUC and I have worked through some issues that I had with his company in the past. he is putting these together based on my request and my tech info I provided him with. I guess if there is any trouble with them it will be my fault not UUC's

How hard would it be to get replacement rotors if they are limited run only?

What rims will clear the V2 rotors and 6-pots?

I'm interested but I don't want to have to try to find new rims.

Also as others have said, we've been burnt by UUC before (me 2x on the Motor Mounts, and 1x on the trans mount), what kind of assurances do we have that these will work?

Also is there a chance we could just re-drill V2 front rotors to fit our bolt pattern? We've successfully done this on the Subaru 5x100 and 5x114 (WRX uses 5x100 and STi uses 5x114, so when we need rotors for a Brembo conversion on the WRX we have had a run of stock STi Rotors re-drilled to 5x100).

The V2 Brembo calipers don't seem to stick out much further than the V1s. Methinks. 18" wheels have been shown to fit, albeit tightly...

That's good to hear. So long as we can put a piece of tissue paper in there it's good enough for me!

Yep. zzilla posted a pic of the V2 front setup behind some 18" CCW Track wheels and they fit. He also mentioned that the big brakes also fit behind stock wheels. Now, I am just concerned that they might not fit behind my 19" CCWs because I actually think the stock 18s have a design that allows for more clearance inside the wheel because the spokes don't curve inward very much at all, compared to the aftermarket CCWs.

I just bought a second set of stock V rims for track use,
so clearing the stock rims is at top of my list (and sounds like this kit SHOULD do that, I hope)

I want to reask the question, will the kit work with stock front V1 rotors? can I purchase the kit without UUC rotors?

This would be a great upgrade and I hope it comes to fruition for the ones who do want it.

That being said, if the rotors are 2 piece I would like to see what aluminum the hats are made from, the flange thickness of hats and what kind of bolts are being used.
I have seen poorly designed and constructed two piece rotors fail on the street and the track with horrible results due to improper material and heat treating of the aluminum hats(fatigue mostly), bolts tearing out of the hats due to improper flange thickness and poor bolt choices!

Also, using the V2 calipers, I would be a little wary of how the brake proportioning would be affected without upgrading the rears or adjusting the hydraulic proportioning of the system, which is slightly more complicated in an ABS system(but doable).

Luke,

With peoples concerns with UUC, why not approach Performance Friction to see what they can do? Not knocking UUC at all, they make some great products, I just think in the braking department you cant find a better quality and tested rotor than PFC, and the pricing is practically the same as the UUC and Racing Brake rotors. Not only that, but the PFC rotor and PFC pad combo would be better and we could probably get a better deal on that kind of "package". Plus I know they're trying to get into the CTS-V market, so I think this would be a great opportunity for them, as well as a great benefit to us. Just an idea....

+1 on this. smb has a good point. I was all about the RB kit, but it really looks like that ain't gonna happen, so maybe we can get different companies on board. I am down for this upgrade (barring any crazy brake bias issues, which could definitely be a possiblity) and I don't really care which company brings this retrofit kit to market, just as long as one of them does.

On this topic, for some reason I thought that I read somewhere that the rear V2 calipers are the 4 piston fronts that the V1 have. Is this correct?

Reask? Who else had asked such a non-sensical question? :confused: Calipers designed to fit on 15" rotors are not going to fit on 14" rotors.

Not that I don't believe you, but do you have some specific examples? I've never seen or heard of a 2-piece rotor failing, so I have to wonder if the ones you saw were just plain old crap. While UUC may not be the pinnacle of brake technology, there are plenty of people running UUC rotors without issue (much more so in the Bimmer world than in the Caddy world), so I don't think there's any reason to doubt their rotor designs.

My only question is why wouldn't they be floating rotors? That takes away one of the big advantages of a 2-piece rotor.

Oh, and definitely add me to the list of "very strongly interested", Luke.
