4. Our Triumph runs the 185/65R15 Hoosier Speedster, a vintage-looking radial designed for competition. We fit a new set of this test day since the old ones were finished.

5. Time to actually get on track. After setting our tires at 21 psi all around--our usual pressure--we ran a few warmup laps.

6. On a lot of older classics, a solid rear axle limits the alignment settings to zero camber and zero toe. Up front, though, camber, caster and toe are usually adjustable. Our TR3 runs about 1.5 degrees of negative camber up front. To achieve that much, we slotted our upper A-arms, allowing the tops of the spindles to be moved inward. To hold the spindles in place, we added these custom wedges.

7. Caster can be tweaked from side to side as needed. This stagger helps the car through turns. For the downtown Savannah race track, which features mostly left-hand turns, we add a bit more caster to the right: 2 degrees on the left, 2 3/8 on the right. Your stopwatch--and data system, if you're running one--will help reveal the correct answers here. How do we adjust caster? We run Jaguar XJ6 ball joints. They're similar to the Triumph pieces but are a little slimmer, meaning we can shim them back and forth by about an eighth of an inch.
