Last night, I had a new set of tires put on and a fresh alignment (done w/ me in the car). The new tires are Toyo T1-Rs (195/55/14 on stock 1994 aluminum). Going on Lanny's specs, here's the before and after numbers:
Btw, what are "SAI" and "Included Angle"?
BEFORE: Front caster (L/R): 4.5° / 3.8° camber (L/R): -0.7° / -0.6° toe (L/R): 0.05° / 0.05° SAI (L/R): 12.0° / 12.1° Included Angle (L/R): 11.3° / 11.5° Rear camber (L/R): -0.6° / -1.0° toe (L/R): 0.20° / -0.20° (so, that means the back of my car was always pushing to the right, huh?)
AFTER: Front caster (L/R): 4.7° / 4.7° camber (L/R): -1.2° / -1.2° toe (L/R): 0.05° / 0.05° SAI (L/R): 12.6° / 12.6° Included Angle (L/R): 11.4° / 11.4° Rear camber (L/R): -1.7° / -1.7° toe (L/R): 0.05° / -0.05°
Disclaimer: I'm no alignment guru, I have only basic understanding of the terms and how they affect performance.
Unfortunately, I haven't had a chance to play yet. They hit on everything except the caster. 4.7° was as close as they could get to the
5° spec. The following other concessions were also made: their machine does toe in degrees not inch-fractions, and only to 2 decimal precision, so 0.05° fit between the 0.045° - 0.075° spec; camber is only accurate to 0.1, so they got -1.7° for the rear camber instead of the -1.75° spec.It looks like they did a pretty good job, and for HALF what I paid for my last alignment.. any comments?
