From Pedel faster on S2KI:

A proper alignment is important for autocrossing, and compared to the other changes you'll be making, a bargain at less than $100. Individual alignments vary, but for the AP1 cars, the general consensus falls in the following ranges:
  • Front toe - 0" to 1/8" toe out
  • Front camber - -1.5 to -1.75 degrees
  • Rear toe - 1/4" to 3/8" toe in
  • Rear camber - -2.0 to -2.25 degrees
If you want it straight from the horses' mouths, here are alignment settings posted by the top three finishers at the 2003 Nationals: Each driver's shock choice is noted since cars on stock shocks tend to be rather more twitchy than cars on aftermarket units. Drivers with stock shocks may want to consider more conservative settings (e.g. more rear toe-in or less front camber). Likewise, alignment settings should be adjusted for cars not running a 1.25" solid front sway bar or staggered tire sizes.

There were no UK specs for the AP2. That alignment was done in the UK after they were complaining about the car having a tendency to oversteer. The suspension was revised on the AP2 so hence they didn't have a different alignment for it.

The track specs that I got happy with on my AP2 were

Front
Max Caster but matched, got 6.4
Camber -1.7
Total Toe Out ⅛"

Rear
Camber -2.1
Total Toe o" (no toe)

I don't think that I'll do any more experimentation beyond this.

On my AP1, I had a lot more toe out in the front and substantial toe in in the rear.

The only issue is the uneven wear on the front skins because of the toe. I take most turns pretty fast so the quick entry response from the front toe is okay with me. I thought that it might be twitchy in a straight line but that's not the case.

OK, no UK Specs for an AP2 ... so does anyone have suggestions for what would be a touch more aggressive setting? MY07, I'm dropped on Swifts w/ Koni Yellows - with Direzza Z1 Star Specs. Maybe just Factory settings on Toe and Caster, then pushing the Rear Camber out a bit more? This is my DD, but I want to have the rear firmly planted / at the same time not COMPLETELY destroy the tires on the inside. Suggestions?

camber wont wear out your tires... toe is the real killer

help ???

Does the specs change if you have bigger tires ?? Im running 265/35/18 on the rear and before I got new tires and an alignment my rear tires were wearing real bad from the inside out. Old tires lasted about 4000 miles and the insides were gone. Now, I got new tires and alignment and Im still worried my tires are still wearing from the inside out. After a short drive I felt the tires and the inside was hot and the outside was cold on both tires !!! WTF ?? Tires are too expensive to be replacing after 3-4000 miles. Any help would be great.........??? Do I need to have different settings than stock ? They have the rear specs on my car @
Camber -1.5 deg on the left and -1.4 deg on the right
toe 18 deg on the left and 20 deg on the right
They claim
camber -1.7 to -1.3 deg
toe .16 to .32 deg as the specified specs factory settings ??
Are they ok ?

The more negative camber you run, the more the inside of the tire will wear.

07 Alignment

My owners manual says:
front camber -.5 degrees
front toe 0" to out 1/16"
caster 6 degrees I'm going from memory so I might be off on the caster a little.

Rear camber -1.5 degrees
Rear toe in .15" total

For Auto cross I have:

Front camber -1.75 degrees
Front Caster + 4 degress or as close as you can get
Front Toe I have set at 0" but 1/16" out is acceptable

Rear Camber -2 degrees or as close as possible
Rear Toe 1/4" In

I run R-compounds for Racing. This setting is a little twitchy on the street but no bad. If the road is smooth you don't notice anything different.

This works well, and as it turns out when I took it to my Goodyear shop for a percision alignment they already had it in the computer as an acceptable performance setting from Honda.

My current Camber/Caster/Toe settings for my '05 AP2:

-Front toe - 1/8" OUT
-Front caster - +5.5degs
-Front camber - -1.5 degs
-Rear toe - 1/4" IN
-Rear camber - -2.1 degs

When I had my alignment done, the front right wheel camber maxed out at -1.9degs, while the front left wheel did at -1.5degs. Then, the front right was brought back to match the left front wheel settings.

Street driving conditions: The car behaves very much as stock, perhaps with a better steering response.
Autocross conditions: Sweeping curves performance has improved considerably. I wonder what my AP2 does on the skid-pad. I hope it can make it up to the 0.92g lateral acceleration as of the AP1... Slalom performance requires the driver to be some what more awake, as the loading on the car shifts from one side to the other...it wants to bite when on the edge...

Street driving and autocrossing is done with the stock tire configuration, using Dunlop Direzza Sport Z1 Star Spec. I'm not that worried on the tires wear, the alignment was done when they were at more than half way done. Next upgrade will be a set of R comp tires...perhaps next year

I found some useful info at the honda press release site:
http://corporate.honda.com/press/art...20010221001307
although, I couldn't get a hold of the for the AP2 tech specs in there.

Skid Pad

I have an accelerometer in my car when I race. Don't know how accurate it is. But, I was getting 1 g on street tires part of the time on wet asphalt. On R compounds I can get a consistant 1.25 G with an occasional spike higher. The longer I can hold the car at the higher g levels the better my times. I don't know how the accelerometer would compare to timing laps on a skid pad.

Out of Alignment Easily

Does the S2000 get out of alignment easily?

I had a Mustang for 8 years and 100,000 miles and never had to align the frontend. I had to on my S2000 at 25,000 miles, maybe a bad pothole after this winter!! Ther backend was fime but the frontend was out of specs, with tire wear to prove it.

TIA

How about the people that don't track their "S"?
My alignment is(now)
front camber 0(L/R) tow 0
rear camber -1(L/R) tow 0

I hope this gets me longer tire wear as I put over 30k miles on my "S" a year and so far I don't notice to much difference in how the car feels on the "street". If it was on the track I know it would not be as fast with this alignment but I would still be faster than a lot of other cars. It all depends on how you drive your car and what you want out of it and how much you are willing to spend on tires for 1 or 2 seconds at the track.

I am no longer tracking my S but I do spend a lot of time on twisty backroads with my Miata friends. So my car is aligned aggressively. I am willing to sacrifice a little tire wear. after all, that's why I bought this car in the first place.
