I recently installed the factory

and need to get it aligned. I'm tempted to just use the factory "R" settings below, but wanted to get a little feedback (e.g. I think there is room for a little more negative camber on the fronts). It will probably see only 1 or 2 trackdays per year (max), but is mostly used as a weekend car and I prefer to have it tuned for the street. I'm running
Michelin PS4S
tires in the factory 18 sizes: 235/40/18:265/40/18.
Factory settings call for a touch of toe-out front and rear:
Front Toe = +5 min (total)
Front Camber = -45 min (per wheel)
Rear Toe = +5 min (per wheel)
Rear camber = -1 degree 50 min (per wheel)
Thanks!
Negative toe is toe-out, positive toe is toe-in. Rarely do you want toe-out on these cars.
For a street car with occasional track, I'd suggest 0 toe up front and a slight toe-in in the rear.
I'm not sure what "min" is referring to... I'm used to seeing inches or millimeters for toe and degrees for camber.
You'll find that -1 to -2 degree is decent camber for a street car on the front and will help discourage understeer on the track. You may want a bit more negative camber for track days.
The rear is pretty reasonable around -1 to -2 degrees camber as well.
A little more or a little less on all alignment specs based on the track, your driving style, and how you feel the car needs to be adjusted to be more balanced.
Ah, sorry, I thought +ve toe was toe-out.
"min" = minutes. 60 minutes = 1 degree. So, for example, it calls for -45 minutes of front camber = -0.75 degrees. How about the following (in degrees):
Front Toe = 0
Front Camber = -1 (assuming this much is possible)
Rear Toe = "slight toe-in"
Rear Camber = -2
Usually you should be able to get about -1.6 out of the front shocks mount slots. They may not be even side to side so just use the lowest camber number on both sides in the front. As MNIWT mentioned, -1.8 would be fine in the rear. As long as you stay close to 0 toe in front and 12 minutes toe in in the rear, your inside shoulder tire wear will be minimal.
Minutes! Now it makes sense. Sorry, it's already been a long week...
