These tires will only be for Autox only, I have a set of stock street tires I drive on daily. I am running 245/45 square now for autox only because I already had the tires from another car, but when I did go to this square setup it did reduce understeer.

Why not 275 rear? If I run 245 front and 275 rear then I have not reduced stagger so understeer should still be present. Keep in mind I am mainly running autox on these these tires so speeds are mainly 2nd gear with some 3rd gear, if I was running track then it would be 3rd gear and 4th and at higher speeds the understeer starts to go away.

If adjusting my camber to around -2 to -2.5 will allow me to run a 265 or 275 rear and still dial out the understeer in autox that would be fantastic because I could put down more power without breaking traction. I do realize my current 245 rear is a little small for a 333hp car.

Just hoping some of you guys have experienced this scenario so I can order the correct size I need.

Thanks.

I'm already running 245's front and 275's rear.

-1.8 Camber in front, -3.0 camber in rear.

Minor rubbing in the front, but I'm thinking this camber shimming would fix that.
