Hi

just did an alignment, what do you think about these numbers?
Street with track 5-6 a year.

Looks good, especially the front. I would think you could hit more negative camber on the rear?

Looks like a good compromise. You should get some benefit on the track and still get some life out of your tires on the street.

If this is a DD with 5-6 track days a year, you'll definitely wear out the inside shoulder especially the fronts too quickly. Also, a zero toe on each side is sometimes frowned upon for street driving. A touch of toe-in with zero thrust is recommended. If this is a weekend car with 5-6 track days a year, then it's a good compromise. Negative 1.5-1.7 in the rear is acceptable, the tires are so fat they do not need all that much negative camber. IMHO, as always.

Ok, that probably means that I need to track it more

It's a daily driver but only drives maybe 10 miles a day, so hopefully they won't wear out to quickly. I wish there was a way to easy change alignment before track....

They won't wear. The rears wear twice as quick as the fronts anyways and your rear alignment is within Porsche recommended street tolerances. As is your front toe. The only thing you have that is different is your front negative camber.

Toe is what makes tires wear faster. With extra camber, they wear at the same rate, just unevenly. The exception is if you have so much camber that only half your tire is touching then it will obviously wear twice as fast. That is not the case with -2.

You can always flip your fronts, even if they are asymmetrical, if they wear unevenly. Just take your time in the rain and know that running asymmetrical tires backwards will not shed near as much water and you've got less grip than normal.

Or rotate them from rim to rim...Outside edge on the left becomes inside edge on the right.

Isn't that the same as flipping them? And yes, I know Kauai Gold is not conducive to spatial geometry problems.
