    This has jumped up from the dream list to the reality list. Great work documenting your work. Its kick ass that they fit behind the stock hoops. So that ball park figure I think I read was 2600? for everything?

    Are our brakes not that good? I am really impressed with them, but I can't say too much since I have never tracked the car.

    Yes they are that good the "OEM "calipers .But like in all motorsports / modifications/show cars/ race cars there is always that edge to make it better.

    "GROUP BUY" on these rotors comming very very soon stay tuned I just need to get one more piece of info.

    My rotors are the floating version but it looks like I will not be able to test track these untill after "SEMA"

    I was always happy with my '04's braking. But my '09 V brakes better with 4200lbs than my '04 did with 3850. The V2 brakes are Herculean!. It's a pretty easy swap, so those looking for more need not go far.

    And, remember, it's cheaper to gain 50-100ft in braking zones than it is on the straights...

    The V was equiped with Bridgstone RE-11 tires in OEM size, PerformanceAFX 2pc fixed mount rotors, V2 calipers loaded with Cobalt Racing XR1 pads, while the Vette had OEM run craps and OEM brakes. The V consistently stopped in a little over half the distance of the Vette, even after switching drivers. I know, we should have used a Z06.
    Isn't this more a testament to the tires? The stock brakes on a C6 should be more than enough to engage ABS, especially with the crap GY GS:2 OEM tires. More brakes will not help past that point (except in fade resistance). I suspect the stock V1 brakes were more than enough to engage ABS on the RE-11's as well (though I've never used that tire).

    A more interesting test would have been to measure the stopping distance of the V before and after. It would show whether the brake bias had been improved or worsened. Though having more fade resistance vs more ideal brake bias is probably a fair trade-off on a road course. On a street-driven car, in a panic stop, not so much.

    That said, they look great and it's great to have this option available.

    Actually I did measure the before and after and nothing was lost. I prefer to get some track time on this set up and then give a full report. After the first weekend in October we will know "the rest of the story".

    Aurora40 all good points.

    Same project, different angle for those who prefer 5 lug wheels. Bob can give you whatever bolt pattern you wish. 5 x 120=CTSV2 & 5th gen Camaro options
    5 x 4.75=just about anything else.............

    Just for a recap. The V2 calipers bolt up where the stock V1 calipers were with no adapter needed? Also these calipers will fit behind stock wheels?

    Cool, thanks for the info. And I look forward to hearing how they do on the track.

    Yes as per yooper: The 12mm V1 steering knuckle caliper mounting bolt holes need to drilled out to 14mm to accept the V2 caliper mounting bolts. Once drilled this is a bolt-on upgrade

    I wonder if V1 can attain sub-100 ft braking from 60mph with these?

    Not really relevant from a purchasing perspective but would be a cool fact considering the benchmarks out there...
