    Check all the weather striping first, make sure it is not worn in any places. Remember your car is now 11 yrs old. Stuff starts to rot after a while. Even if it is just dry rotted it's not going to seal correct. Are you making enough power that you have twisted the body at all? If so you might be screwed.

    Wind noise is a factor at high speed. Adjust your windows to t-tops, get your driveshaft balanced, make sure your tires are balanced and rated for those speeds..


    and then prepare for speeding ticket

    Give it a good coat of wax to reduce drag. lol
    What Joshie said. I would check tires first. What brand do you have and are they balanced?

    I got mine to 144 once and it felt like 65.

    i believe you are right about weather striping. where can i find a replecment for that? and i did not understand what are you saying by "Are you making enough power that you have twisted the body at all? If so you might be screwed" can you explain?

    If your car is making more then stock power and you have not yet put frame connectors on it yet. You could have put a tweek in the body a little . If this has happened then things aren't going to line up correctly. This would most likely be done through hole shots from drag racing with slicks and or drag radials. It's a long shot but, it is possible.

    only reason i like germany because of i can speed and i dont have to worry about ticket. also trafic rules are great in here. there is a fast lines and slow lines and everyone stay where they have to. so you really dont have to worry about someone going to cut front of you.
    after a while 120 and less feel like nothing and that is the sad part. because you are so get use to speed. also TA does not show speed like some high cars.
    i do love adrenaline rush and i do love 11 years old TA can beat some new, over rated and expencive cars...

    so, finally some domestic help!

    first: 155 is the fastest i've hit in my z28 so far. not a speed these cars are really built for, but manageable. and it is loud.
    the main problem is the construction of the frameless side windows, mine lift from the weatherstripping a little at the back edge when i go faster than 120mph. and of course the t-tops have edges that catch wind and produce noise.

    2nd: vibration is never good, i had problems when i still had the stock 16'' rims. after switching to 18'' and hankook tires with a 300 km/h rating, it got considerably better. the best move though where the subfame connectors, the car feels like a rock now at speeds around 120 - 130mph. make sure your tires are balanced and have enough pressure, 15 to 20% above what the manual says. i run 2.5 bar on all four.

    finally: don't race on the autobahn, it's dangerous.

    one more thing: if you haven't already, ditch the stock shocks, they're useless. i run bilstein hd.
