Track Alignment on OEM Suspension

[Read T]

Been searching, but I can't find a good link for people still running the OEM suspension. I will be getting an alignment a few days before my next HPDE and normally just tell the shop to put everything to factory specs. I really don't know how much adjustability the stock suspension has in it besides toe (if it matters I have Nismo struts/springs). Logic would tell me that I want to max out caster, run a bit more toe out up front, and a bit more camber all around. That being said I really don't know how much can be dialed in. What should I tell the shop? The shop is managed by a good friend and Z33 owner and I get unlimited lifetime alignments so I can return the alignment to stock shortly after the track day.

My HPDE instructor and friend who runs miatas/mustangs suggested

2deg neg front, 1.5 rear. 1/8" toe out front, 1/16" toe in rear. Max neg caster front. Then you'll feel a different car!

Any tips would be greatly appreciated
