    Good luck with that James.

    I'd love to get some more ITR cars out there. I need someone to race against. Even if it's Mustangs and Camaros

    My bad, that motor is rated at 189.
    Per the process the early Z3 should match the 325 weight as you say, while the later should be around 2820 lbs. Could run either motor with the VIN rule, or the 3.0 for that matter, though I doubt many would want to run that heavy.

    Here's another question since some of our ITAC are on this thread. About a month ago I sent in a request to the CRB for proper weight specs for my 968 running in STU - never heard a word. What's the best way to get feedback on that question?

    Looks like the GCR says 3300lbs Ben. But we wouldn't be the ones responding to your letter on that anyway. Not sure if there is a STAC.

    Am I missing something here? The STU weights specs are a displacement-to-weight calculation, not specific to any vehicle (unlike STO). Alternatively, you can run under IT prep rules, meaning your already-defined IT weight...

    I like Greg's answer better :-)

    I found the weight to displacement grid in the GCR - 3300 lbs it is. Better to race STU in IT trim.

    Seriously thinking about crashing the Runoffs in my Hillbilly RV.

    I'd definitely agree with the 968 having a low power adder, such as 15%, but the driveline loss should be more like 18-20%, same as the rest of us (924/944's) - that torque tube and transaxle eat up a lot of juice!!

    Ahmen to that, Vaughan.

    What is the power adder for the BMWs?

    What do folks think a 100% 968 should make at the wheels?
