So far, totally stock suspension here and have been using 255/35-19 / 275/35-19 RE71Rs, and it sure feels like it could handle 30mm width stagger (i.e. 275/30 and 305/30) since it is so well balanced with 20mm.
Unfortunately no. Autocross season hasn't really started here (DC) and I had to miss the final round of the refrigerator bowl because some 11th hour life stuff got in the way. But I'm registered for PCA and SCCA's first events here on the 21st and 28th. I'm an OG lci m2 btw. All stock. Have a Hotchkis front bar in the shed that I'll throw on after I have a few baseline events with the car.

What's everyone running for alignments on OG/LCI m2? Most alignment talk I find on the forum is centered around cars with camber plates, lowered etc.

From searching I THINK the stock alignment specs are:

Front Camber: -1.5
Front Toe: .05 deg (.1 total)
Rear Camber: -1.29
Rear Toe: .08 deg (.16 total)

From what I think I understand as of now, caster is not adj and there's not much if any additional neg camber available. So really this is a game of toe?
