Here is a dialogue between Ed and I in Facebook we had for tires and suspension for folks reference.
-------------------------
Ed: What are your alignment specs?
Rich: Funny you should ask, as they just finished my alignment. So when I swapped the rack I was off on Toe only about 1 1/4".
I'll set the camber to -.5 for the travel between home and track. Reset to -2 once I am there.
All better now. Fluids and brakes tomorrow.
Ed: Next time try zero toe. Easy on the tires and crisp turn in. The rear naturally toes in when you lower it so the car will still track straight.
If you adjust the camber you will alter the toe and might not achieve the tire saving wear you're after.
Rich: Ed, thanks! Am I running too much camber for general circuit track events? I realize it differs from car to car.
Ed: Rich - so that's hard to say. I would not say you're running too much camber but there are some things to consider.
The more negative camber you have the more straight line braking you give up. Running only 225s up front this would be a consideration for me. Are you trail braking or doing all your braking before you start your turn in?
Adding caster gives you more negative camber when turning. It also makes the steering more heavy but I honestly don't notice, even with 245s on the front. Caster allows you to back off on the negative camber a little bit.
You're driving your car to the track and on the street. I think there is real value (in terms of time, money and being used to your car) in driving the same set up all the time. Set it to something aggressive that won't kill tires and learn to drive on that till you can out drive the car.
All that said, Ricky Marrero is probably the better one to speak on this subject.
