I agree with Duane and Agro 1, the car is a beast. I just returned from a 4000 mile trip in my Arntz with the Butler hard top on it and much of it was at 100+.
The procedure is this:
1. Glasses must be spotless.
2. Polish the Lexan windshield until it's perfectly clear.
3. If you're traveling toward the sun, prepare strips of duct tape as a visor.
4. Take the wallet out and put it in the side pocket so my big rear will fit in the seat.
5. Tighten down the 3 inch harness until you cannot move.
6. Check the Valentine 1 and the radio scanner are on.
7. Roll the ear plugs into tight little cylinders and insert them.
8. Fire it up and hold on!
Seriously, driving the Cobra at high speed requires really good eyesight and really good tires. My Hoosier race tires used to drive me crazy, jerking the car around. The Toyo Proxys are a revelation. Straight and smooth. The noise from my Jag-you-are differential and the wind are the real limiting factors. At 160, all you can see is the sky.
