Picture from Mark Windecker, at Mid Ohio Sports Car Course in 1987. Unfortunatelly the Tim's Corvette will not finish the race. Final qualifying position was 8 with 26 starters.
Driveline: The car was built on a surface plate in Tim's shop. The frame was fabricated from large I-beams and 4x6 tubing. Design was derived from information about body and chassis layouts, provided by GM contacts. 5-speed Saenz trans from Argentina with dog clutches and changeable gears. Franklin IRS axles. Cadillac halfshafts and hubs. The rear suspension was Tim’s own design and fabrication using lessons learned from his first car. Shocks were by Delco since he had contacts there. Front suspension was also Tim’s own design and fabrication using lesson learned. Brakes were 13" Tiltons with GM power assist. Later changed to 2 master cylinders with remote reservoirs to avoid lockup at high speeds. The car was originally planned to use ABS but this was outlawed before the car was completed.
