Alignment Specs to give your alignment guy or gal.

A proper alignment will do wonders for the way your car drives. We call it a performance alignment. The performance alignment has more caster for better stability and Zero or some negative camber for added grip instead of the positive camber the cars came with. Negative camber gives  the car more grip but is driver specific. Grandma won’t need as much camber as grandson driving the same car. Tire wear patterns on the street or tire temps across the tread on the track will tell you how much negative camber to use.

Arning drop ~ Shelby drop ~ 1″ upper arm drop

Overall performance improves when you lower the upper arm mounting point on the 60-68 Falcons, 64-70 Mustangs and certain other Ford/Mercury vehicles.

In stock form, the top of the tire moves outward as it moves up in the wheel well. Moving the upper arm mounting point down a bit, changes the geometry so the tire moves more straight up in the wheel well. That gives the car better grip and handling. There’s no down side to it other than having to drill four half inch holes in your 50+ year old classic.
