Dave Shotz drove a '99 TransAm WS-6 to second place at the '99 Solo II National Championships. Here's his car:

I ran stock exhaust manifolds, and stock throttle body, and intake. I did have aftermarket Air Lid, and K&N filter. I ran a 180 thermostat, MSD Wires w/ NGK plugs. MAC Off - Road Y-Pipe (no cats) into 3" DynoMax Race Magnum Muffler.

Car dynod at 328 HP, 370 Torque corrected at the rear wheels.

I used CCW 17X11 wheels, with 315/35/17 Kumho tires around all 4 corners.

I used The Factory 1LE Koni Double Adjustable shocks, with Global West's Coil overs on the Front, and Global West Springs in the rear. I used (at different events) the Global West Trac-Link, and the Herb Adams TQ arms. I used the Factory sway bars, with Custom Heim Joint end links on the front bar, with Poly Bushings, no changes to the rear bar, or bushings. Control Arm bushings stayed original in the Rear, and the front Lower Control Arms. The Front upper control arms were offset to help gain camber (but ended up costing me caster, don't think I would do that again.), Hotchkis Strut Tower Brace

McLeod Aluminum Flywheel, with Smaller Diameter Clutch and Pressureplate.

Sparco Evo 2 Race Seat

Torsen Race Unit Limited Slip, Factory 3.42 Gears.

Porterfield Brake Pads, front Stainless Steel Lines, Wilwood Proportioning valve to decrease rear brake.
