I wanted feedback regarding what alignment settings would be the best for dual purpose street (weekend car) and track (hpde). I have a 2013 grand sport running a pfadt camber kit. I will be running re-11 as track tires and I will be driving my car to track events for the next year (2 hour ddrive minimum) until I get a truck/trailer and want settings that will give me descent performance while not destroying the inside edge of the tires too prematurely (although I realize this is ultimately unavoidable when running a dual purpose alignment). I was considering running pfadt s listed street/track settings. I want to avoid swapping street and track alignments for track days until I get a trailer. So, for any members with experience in this area, I'd love to hear your feedback and suggestions!

This would be a good starting point and you can adjust from there:

Front
Camber: neg 1.5 to 1.8
Caster: pos 7.2 to 7.6
Toe: 1/16" toe out total

Rear
Camber: Neg 1.25 to 1.40
Toe: 1/16" to 1/8" toe in total


Toe is going to effect tire wear more than just about anything but will also dictate how the car feels on track a bit as well. Get used to bringing a 13mm and 7/8" wrench with you to the track and familiarize yourself with how to do toe changes at the track and before you drive home. Normally I would have 1/8" out at the front and 3/16" to 1/4" in at the back of the car for a track car as a starting point but it will destroy your tires on the street.

Camber adjust to your tracks. You can get away (typically) with a bit more camber on it and not kill the tires unless your putting 20k miles a year on the car.

Thanks! Should I look into getting home alignment tools to use for track days? Also are running those toe settings ok for regular street and highway use or should I set them as close to 0 as possible when not at the track?

Anthony beat me to it, those are pretty close to the settings I use. As mentioned, for street duty I set my toe for 0 F and 1/16th total toe-in R.

I also run a catch can and a camber kit.

Having the tools to do the changes is never a bad thing...especially if you want to make some quick changes at the track. Document what you do and you can always go back to where it was before hand.
