The alignment shop that is going to do my alignment this week is asking for specs. McRib suggested an 1/8" of total toe out,

I will be using the SPC camber bolts so for camber I'm thinking I should just max it out.

What other numbers would you guys suggest?

Oh, this is for track duty

Yep, also I wanted to say that I didn't cook those #s up myself. I'm lucky enough to have a few friends that campaign FWD race cars and draw on deep engineering resources.

That 1/8" total toe-out is a time-honored setting, and I really like it. Max negative camber, and see how things go.

On a related note, I think I just ran my last session with these BFG R1 tires. One tire is showing a small chunk, exposing a bit of steel belt (these are not offroad tires!). Anyhow, BFG recommends -3, max. Note that many tire manufacturers specify ideal/max negative camber values. The R1 tires were fine at -4, showing good wear characteristics, but YMMVG.

I haven't tried the R1's . I considered them briefly but went with the Nitto's because, at least in theory, they would provide some wet grip. The R1's would just float down the track. On my M3 I had Michelin PSS's on my street tires, but on the FiST my stock wheels have all-seasons so my track tires have to do double duty. We'll see how the NT01's do in the wet and I may switch to the R888 if they don't do well. Oh course, hopefully I'll have my darn race car done by next season...we shall see

But yea, on my M3 I ran the NT01's at -2.9 and they seemed to like that. Turn-in was good, but a little throttle could assist that (but less so in the FiST) so I'm gonna have them max out the camber an then go from there.
