Default Spec Miata alignment

What are some alignment specs that are common on a race prepped Miata that's running R-compounds?

I'm ---- (you didn't capitalize the thread title for instance).

There are people who are actually diagnosed with OCD.

There are really really bad cases of OCD.

Then there's this setup guide: http://www.specmiata.com/download/sm_setup_guide_v2.pdf

I have pretty much based my alignment specs off of this:

Rear camber : -2.5*

Miatas over 180whp or so can add +1/16" total toe in at the rear to attenuate corner exit power oversteer.

It depends on the track and the tire you are running (888 vs ra1), to be honest.
To give you an idea though, for Northern California its usually about 3.5* front camber, 3* rear. Front toe 1/16" out, rear goes between 1/16" in and 0 depending on the track.

lol! ^that's just about the same specs on my Civic, which I'm running HankookZ211's.
Do the R888's like alot of camber? R888's are likely my next race tire.

They're supposedly a bit faster than the RA-1, but they don't last long at all, SM is ditching the R888s to go back to RA-1.

0 toe all the way around, in SSM we are limited to -2.5 in the front and -2.0 in the rear, and I am right on the number there. Car is scaled and cross weighted to 50.0% +/- 1% with 2 gallons of fuel to put me at class minimum, which gives a nice neutral car that is a little tight as the fuel load lightens at the end of a 18 lap sprint race.
