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.
