    The Build...

    As some of you guys know, I've been bouncing around the idea of converting the V into a dedicated track car.
    Main use will be to run NASA's ST2 class with the possibility of running in other SCCA classes as well.
    Today, I'm happy to report that the first step in the build process has begun.
    I hope to provide a step by step process that will detail all of the changes from start to finish...

    Vehicle as it stands today road ready is:

    2005 CTS-V
    Light Platinum w/ Black interior
    LS6/6 speed tremec
    11,771 miles

    Current Mods:

    Magnaflow Cat-Back exhaust
    Diablo Predator tune
    Ron Davis Racing radiator
    FG2 Shocks
    UUC Poly motor mounts, tranny mount, and diff bushing
    UUC short shifter
    Spectre Werkes delrin cradle bushings
    Rear Strut tower brace
    UUC Braided brake lines
    GM Performance/Brembo cross drilled rotors
    Motul 600 fluid
    Michelin Pilot SuperSport Tires

    12/4/11: Conversion

    All Fab work for the rollcage as well as complete gut of the interior and removal of all non-necessary parts is being done by Phoenix Performance*
    Last year at the V Performance Lab @ MMC, I met John Heinricy who recommended I get in touch with the owner, Joe Aquilante, who happens to build and maintain some of the Vettes that HeinRocket has had much success with running in the SCCA ranks. It also didn't hurt that Phoenix had built the V that John Buttermore has had his success in T2 so I know they have experience working with V's

    First order of business is to completely remove the interior and begin fabrication on the SCCA/NASA legal rollcage, as well as remove all of the non-essential parts such as the air conditioning and other heavyweight items.
    (BTW, please contact me if you should need any stock interior parts)

    Pictures to follow soon...

    Absolutely Fantastic! Will you be using the offset front upper control arms?

    Re: The Build...

    Are they going to be using a jig for the fabrication of the full cage - i.e., is it going to be something they can reproduce for other Vs or is it going to be just a custom job?

    Pretty certain IIRC they still had the prints for the cage since they built quite a few back in the day. Of course they were also able to add/subtract custom options I wanted

    Joe mentioned that they documented the ones they sold recently and his fab guy is able to replicate them if I wanted them

    GM Racing modified the front upper control arms by moving Two bolts (pivot pts) 5 or 6mm closer to the chasis producing at least 2.5 negative camber. When combined with thier custom sway bars, FG2 shocks, and R compound tires the fun meter starts to rise on the road course.

    Nothing set in stone as of yet other than to try and shave off as much as I can in increments.
    2 piece rotors, TD wheels, carbon fiber race seats, carbon Fiber body panels, Lexan windows, etc.

    What I do have is a ratio. That ratio is equal to or greater than 8.70:1.
    NASA uses this "adjusted" weight to horsepower ratio to classify the vehicle. Which basically opens up the door to unlimited performance/body/chassis and aero modifications. Certain items such as a dog ring gear box carry a penalty of -0.2 and other things such as it being a four door allow +0.4.
    I can go greater than that ratio (less competitive), but under that ratio bumps me into a faster class (in this case it would be ST1 with a ratio of 5.50:1)
    My plan is to trim as much as I can and get as close as possible to that 8.70 ratio.
