What do you think about this specs if I am not aggressive driver, my S is my daily commute mostly on city streets during rush hours. I do not autox nor track my SA.

Front:
Camber: -0.10"
Toe-in: 0.00"
Caster: 6.45"

Rear:
Camber: -0.30"
Toe-in: 0.20", for a total Toe-in of 0.40"

If this specs will totally destroy the handling of the car, then I will stay with "Preferred Setting" from Honda Bulletin number A0002294

 

Well you seem to want to take out most of the camber, but it's not the camber that kills tires (within reason) it's the toe. I would suggest running very little toe, perhaps 1/16" per side, 0 toe in front, and run the recommended camber settings. I can't suggest running 0 toe in the rear, because you might get a lot of oversteer in an emergency accident avoidance maneuver or something.

If you ran the toe you're suggesting in the rear, which is even more than the significant amount that Honda suggests, your rear tires would be toast in no time.

By the way you spec'd your camber in inches. I assume you meant degrees.

 

Also consider this: Just because you don't drive hard doesn't mean you don't need to worry about using a safe alignment setting. When someone in front of you slams on their brakes and you end up swapping ends and going backward across on-coming traffic because you took out all your toe in to make your tires last longer, don't say that you didn't plan to get into an accident. No one plans it, but it happens all the time. You need to plan accordingly.

EDIT: You're also not allowed, at that point, to come on the forums and claim the S2000 is an oversteering monster.

 

All the specs are in degrees.

Front:
Camber: minus 0 degree 10 minutes
Toe: 0 degree 0 minute for each side and total toe-in is 0 degree 0 minute
Caster: 6 degrees 45 minutes

Rear:
Camber: minus 0 degree 30 minutes
Toe: 0 degree 20 minutes for each side and total toe-in is 0 degree 40 minutes

AP2 is designed with understeer, that why rear tires are much wider than front tires. RE050 215/45-17 has smaller tread width than many 205/50-17 tires.

 

Thanks for the clarification. My post still applies. If you want to reduce tire wear, you need to reduce toe, not camber.

 

Thanks for your inputs

From the workshop manual preferred setting, I've changed it a little to come up with the above specs, except the rear camber, all others are within preferred setting. Rear camber should be between -1 degree to -2 degrees. I think I may stay with -1 degree rear camber to be safe.

I did not check my alignment yet, but the front tires showed significant inside tread wear at 14k miles, much more than outside or center, I had the fronts flipped last weekend. The rear tires had been flipped a year ago at around 7k or 8k miles and they are very even now, all treads are almost gone, about 2/32" left and the wear bars start to show.

 

TR=S2K,
What does the Honda Bulletin you cite say to do? Is this more current than what the Hunter software for their alignment machines have fir a MY04? Thanks.
Jack

 

This specs is copied from Honda Bulletin for MY99-MY01, * means degree, ' means minute and +/- means plus or minus.

UNCO4SuzukaBlue posted this specs from the 2000-2004 Service Manual:

Caster angle: 6*00' +/- 15'
Front camber: -0*30' +/- 10'
Rear camber: -1*30' +/- 10'
Front toe-in: 0 +/- 2 mm (0 +/- 0.08 inches)
Rear toe-in (pre-04): 6.0 +/- 2 mm (0.25 +/- 0.08 inches)
Rear toe-in (04+): 3.7 +/- 2 mm (0.14 +/- 0.08 inches)

For people like myself who do not drive aggressively want to have long tire life, is this modified specs will do?

Front:
Caster: 6*45'
Camber: -0*20'
Total Toe-in: 0*00'

Rear:
Camber: -1*00'
Total Toe-in: 0*40'

 

I'll say this a third time:

If you want to increase tire life, you need to use less toe, not less camber. Your specs have more toe than stock, so they are going to do the opposite of what you want!!!

The front settings are fine- tire wear is not a problem on the front of the S2000.

For the rear, I would suggest running factory camber (or maybe -1 degree) and reduce the toe to maybe .1 inches total. You don't want to take too much toe or camber from the rear because as you do, you are reducing grip at the rear.

 

TR-S2K, listen to spa-zz. Toe kills tire faster than camber. Reduced camber is receipe to narrow traction limit (i.e. let go suddenly). It's not worth it. The solution for you is to consider cheaper tires and replace as often as needed. A cheaper tire with fresh rubber is most often better than a more expensive tire with aged rubber anyways.
