    Default Future Spec Corvette race clip?

    I don't think Clint is on here, but it was nice to meet you, Clint.

    Just imagine all the other cars are S2 Supermiatas and that I actually have a Spec Corvette.



    I love the parity on the drag race down the front straight.

    Great stuff. Good driving. You really need a race seat to hold you in place. You will pick up even more time and safety.

    You will be a Spec Corvette champ I have no doubts.
    To the right of The Sheriff. Isn't everyone?

    Aside from their cost I never understood why people race them.

    I ran some 57s. Missed the last session because one of the tires corded, which apparently for the Rival-S has no obvious effect on performance.


    (No idea what the noise under braking was in the early part of of the video, except somehow a strip of tread hitting something? Never happened before, didn't happen for rest of session)

    Fast!
    Suddenly I lost all my interest in modern German cars. Need a vette someday.

    Fe4, I remember your car being pretty stock other than big square tires. Can you list your mods pls? I'm mostly curious about brakes and cooling. Im wondering what you can get away with for HPDE vs a full on race car.

    I'm looking at C5 Z06s these days. The more I learn, the more impressed I am with these cars.

    Sure, the full setup on the video above:

    ~2.2F/1.3 camber
    4 rear wheels
    315 Rival S
    Willwood H compound front pads
    HP+ rear pads
    5W50 Redline engine oil
    RBF660 brake fluid
    Warm weather coolant/water ratio
    Angel wings pads
    Backpack behind seat
    Aluminum tape on suspension joints
    Trailer hitch

    There is a good thread in the Corvette forum above this one about C5 Z06 track prep. Everyone has a different opinion, I think. I have had pretty good luck without touching anything. But I accept avoiding hot days, avoiding full sessions, avoiding race tires, cooling off the car aggressively (keep the plates on so I can drive up and down Lerdo Hwy), never bringing less than 2 extra rotors to the track, etc. It's not the best way to maximize your HDPE dollar, in a sense. And I have run 100*F days and done full sessions, but sparingly.

    The car still has the original shocks, calipers (weirdly the rear dust boots are ripped, but the fronts are fine), etc. The front LCA bushings are still okay, the front UCAs have pulled off the rearward bushing a bit but are hanging in there.

    On an 80*F day at BW the oil will plateau around 300*F and water will end up around 235*F. Above 90*F I think plateauing coolant becomes is track dependent. I have never gotten oil above the three hundred teens.

    On a track like Streets CCW, Laguna Seca or ACS event an all-out pad like H compound will start to go away, but not in a way that makes the car feel hopeless.

    Things I have replaced through 50 track days:
    Starter (track related heat death)
    Crank sensor (probably same)
    Radiator removal and reinstall after cleaning
    Valve springs (preventatively)
    4 hubs (just 1 rear was really bad, for the fronts the hub bolts just loosened up and made it seem like the hubs were bad)

    It's probably time to retire the car after this much track work though and just use it for hauling. tx.jpg But a great track car.

    A 14 year old C5 is on pole for Saturday's SCCA Runoffs at Indy in T2. The old C5 chassis dates back to 1997 and still competitive!!!!
