I am planning on going to the track soon and I have an all stock 04 s2000. I've been thinking about taking it to get it lined up, does anyone know the best settings for a stock ap2?
Thank you.

What tires and what driver skill level?

Usually when someone asks "what's the best XYZ" for something complicated, they're generally on the newer side.

The answer to "what's the best XYZ" is almost always: "depends."

If someone asked "what's a reasonable XYZ," that's a different story.

Like CKit says, "It depends." For newer track drivers the stock alignment settings are usually a good place to start. But if you do want a better handling alignment and are willing to give up some tire life then all you really need to mess with is camber, front and rear. Stick with the stock settings for toe-in and caster. Extra camber will put more pressure and wear on the inside shoulder of the tires so they will wear faster but you'll have more rubber in contact with the pavement in corners.

Probably the "best" alignment specs for a stock S2000 that's being pushed hard on course or track is to set maximum negative camber front & rear.

Here's the stock specs:


Alignment Specs (all years)

Caster 6º +/- 15' (6 degrees plus or minus 15 minutes) or the range of 5º 45' to 6º 15'

.....Decimal degrees: 6º +/- 0.25º or the range of 5.75º to 6.25º

Camber Front -0º 30' +/- 10' or the range of -0º 20' to -0º 40' degrees & minutes

.....Decimal degrees: -0.5º +/- 0.167 or the range of -0.333º to -0.667º

Camber Rear -1º 30' +/- 10' or the range of -1º 20' to -1º 40' degrees & minutes

.....Decimal degrees: -1.5º +/- 0.167 or the range of -1.333º to -1.667º


AP1 (2000 - 2003) Rear Toe-In Specs

Inches: Total Toe-In is 0.25 inch +/- .08 inch or the range of 0.17 - 0.33 inch

.....For each rear tire toe-in is 0.125 inch +/- 0.04 inch or the range of 0.085 - 0.165 inch

Decimal Degrees: Total Toe-In is 0.58º or the range of or 0.40º - 0.77º degrees

.....For each rear tire toe-in is 0.29º or the range of 0.20º - 0.38º degrees

Millimeters: Total Toe-In is 6mm +/- 2 or the range of 4 - 8mm

.....For each rear tire toe-in is 3mm +/- 1 or the range of 2 - 4mm

AP2 (2004 and newer) Rear Toe-In Specs

Inches: Total Toe-In is 0.14 inch +/- 0.08 inch or the range of 0.06 - 0.22 inch

.....For each rear tire toe-in is 0.07 inch +/- 0.04 inch or the range of 0.03 - 0.11 inch

Decimal Degrees: Total Toe-In is 0.33º or the range of or 0.14º - 0.51º degrees

.....For each rear tire toe-in is 0.16º or the range of 0.07º - 0.26º degrees

Millimeters: Total Toe-In is 3.7mm +/- 2 or the range of 1.7 to 5.7mm

.....For each rear tire toe-in is 1.8mm +/- 1 or the range of 0.8 - 2.8mm

Thank you, robrob that's pretty much what I was looking for. I know there's not a dead set this is the best answer, just this way usually works a little better than this way type of deal.
Thank you!

I'll be going with UK alignment spec as a novice start.

I used these before I change to 255 all around, it was the best for me using 215/f and 245/r.

You can get a lot of adjustment in the rear for negative camber. I found that not all of it is necessary (for street tire Autox). If kept to negative 2.0-2.5, it helps put power down in autocross. YMMV.

Where newer drivers differ is usually in the rear toe.

Also, lots of neg front can be darty on the street if you're not used to it.

Also, make sure you're okay with how it'll change your tire wear characteristics when not autocrossing.

Basically, it depends.

The more info you can give us about you, your car setup and intended use helps us help you.

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 the general consensus falls in the following ranges:
Front toe - 0" to 1/8" toe out

Front camber - maximum available (generally between -1.5 to -1.8 degrees)

Rear toe - 1/16" to 1/4" toe in

Rear camber - -0.2 to -0.5 degrees more than the front camber

Drivers with stock shocks or sway bars smaller than 1.375" may want to consider more conservative settings (e.g. more rear toe-in or less front camber).

Taken from the s2000 Autocross thread.

Thank you all for the replys, I'm new to tracking cars although iv raced dirtbikes my whole life so I'm not new to the whole racing deal. I live about 15 mins from vir so I'd like to take it out there as much as possible. Its not an everyday car so I'm fine with it wearing a little funny. The front is already wearing more on the inside so I guess its already a little negative camber. Thank you all for the input, I'm just kindof looking for a good starting point.
