not really. 64 dart, subframes with torque boxes, 8.25 with MP circle track springs, i ran between .990~1.14 bars and different configurations of sway bars from solid and hollow 7/8" to 1-1/4" up front to 1/2"~7/8" out back-- both adjustable and non adjustable. boxed control arms, stock uppers with offset bushings, poly on standard strut rods and solid sleeve tie rods. 16:1 manual box. wheels varied from 15" to 17". bilstein or QA1 adjustable shocks.
so there really wasn't anything high dollar in the set up, it was just built as a system and tuned. only the tuned M3's were running away from me, but even then i was knocking on their back door. and these were cars that were trailered to the event. i drove, 120 miles there, raced and drove back. on the same tires.
Well, had. 1970 911E Targa. Actually had two of them, and one motor, which I built myself.
Dumbest mistake I made was to sell it, figuring "I'll just buy another."
