Just got my car aligned today. I had to go to 2 shops in order for them to get it right. The first shop had no idea what they were doing. They couldn't get the caster pass 0.02. Luckily the 2nd shop had some experienced. So the tech told me that it's too aggressive for daily but I went ahead and did it anyways. Car feels great but my tires are basically brand new. So what do you guys think? Will my tires only last like a season?

This is an ap1 with ap2 wheels stock size tires

Front
Camber -1.5
Caster L 8.0 R 7.1
Toe 0

Rear
Camber L -2.5 R -2.6
Toe L 0.13 R 0.16
Total toe 0.29

 

You don't say how you drive your car.
I do a lot of miles in my "S" up in the mountains and coast so I went through tires
in 12 to 15k miles so I went with less camber and no toe front and back in my '06.
I like the way my tires wear now, not just on the inside edge of the tire like before.

thats almost deg for deg my alignment on the ap1

my re-11's are on the wear bars in the rear but have 7/16th up front lol

if you dont rip on the car the tires will last for two seasons, if they wear on the inside flip them dismount them all, left tires go right and vice versa

 

Add a little front toe-in, or you will shave off the inside of the tires, guaranteed. .03-.04 per side (.07 total) is all you need.

 

 

Front caster side to side are off.

 

Where are the UNITS?!
Do you have 0.29 *degrees* of rear toe (which'd be OK), or 0.29 *inches* (= 0.66 degrees = excessive)?

Numbers by themselves = meaningless...

 

Obviously its in degrees.

Yes front casters are different and likely maxed out. If it doesnt pull on a straight road, casters are fine right where they are.

Front toe-in is all you need.

 

Humm. First time I think I have seen front toe in be suggested for saving tires If I track the car and drive really aggressive on mountain roads will this still help wear? How will it change the handling of the car? I will be running 255 all around tires on rpf1 with areound -2.8 camber on the front and 1/8 inch total toe in on the rear.

 

Not obvious to me. Judging by the absolute values, the toe could easily be either degrees or inches. Never take units for granted...

I don't see any need for front toe, and the recommended amount of .03-.04 is a mighty slim window to hit, if in degrees. That's a range of .004"! Touch the car and you'll get that much change.

The shop that does my alignment, the increment is .05deg, which is fine enough resolution for me.
Ask for .03 - .04 degrees, most shops are going to interpret that as 0 - 0.05 degrees anyway.

Every car is a little different, but I've never had problems running zero front toe on any of mine. For sure zero toe is totally OK on the S2000, .03-.04 degrees per side (.06 - .08 total) isn't going to be very much different in terms of feel or wear.

You were talking degrees, right?!


Anyway, rear toe is where most people screw up with these cars. Too much rear toe absolutely sucks, for absolutely *everything* (wear, handling linearity/predictability, turn-in response, *everything*).
I generally run ~0.2 degrees total rear toe.

0.29 is fine *if in degrees*.
0.29 inches is excessive.


Regarding camber, you can run quite a lot without totally killing tire life (unlike toe!). I'm running -2deg camber and 0.2degrees total toe-in in back, and wear is remarkably even so far, at 15k miles on Hankook RS-3s (!).
With 0.29"/0.66degrees total rear toe, tire life is cut in half or worse.
