I have a new set of RE-01R coming and I'd like to get some advise on alignments. I searched, and have become even more confused. Any info is appreciated.

MY07 stock. Driven hard but not tracked. Best alignment? (also, what are stock specs?)

 

Assuming stock width wheels, my personal choice would be a max camber alignment (about -2.0 front and -2.5 rear) with zero toe front and and -0.125 (spec for AP2?) in rear. I don't know what spec caster is, but that would be fine. If you want to back off from this then reduce the camber 0.25 to 0.5 deg.

This makes a big difference in how the car feels. Some will argue about tire wear, but toe settings are the biggest driver there. That's why the stock toe setting recommendation. Any toe out in the front will eat tires very quickly. Any toe out beyond spec in the rear will make the car to tail happy for most people.

I think most S2000 owners see tire wear on the insides

Let the debate begin... again.

Note, a good way to set tire pressure and camber is on a skid pad. The idea for performance alignment is to make the best tire patch contact for the conditions that you drive. It's done with a probe type pyrometer ($100) to check tire temps on the outside edge, middle, and inside edge. The idea is the get the three temperatures within about 10F or so. Differences between outside and inside edge can be altered by changing camber. Edge to center differences by changing pressure. The size of the skid pad should be appropriate to reach conditions that optimize for the driving you plan to do.

 

Thanks.
