    Update:

    at the 2.5 mile, car was doing awesome, faster than the previous run, so it was going to be even a faster overall mph.
    But, unfortunately, the car go sideways at 250mph and spun out.

    Nobody was hurt.

    The cars trunklid flew off, doorskin flew off, rear window flew off, but everything is ok.

    So, the record remains, he still has it, and the previous 2 records, but the 262mph wasn't backed up.

    Next on the list, install the front custom fascia, custom hood, get all the wind resistance down, we should hit about 280mph!!!!

    It's funny how much HP body mods are worth in the wind tunnel.

    I assume the doors are fixed, i.e. don't open anymore? Did you guys put the "flange" at the bottom of the windshield like you were discussing? How about a "tail cone" so there's not a rapid drop-off for the wind coming down off the rear deck lid?

    Just some ideas...glad to hear the car wasn't damaged too much.

    No doors operate normally.

    No body mods is what keeps it in the GT class. As soon as you add a wing or spoiler the car gets pushed to modified class. Once modified class, you might as well add all kinds of stuff.
    This next round will be in modified.

    Ya, front and rear glass are secured, but not enough probably.

    You forgot to include changing underwear cuz I'm sure spinning at 250mph caused some other things to come loose!!
