Forgestar 19x11 square (+56)
(Wheels sit 1/4" inside wheel opening on rear and almost touch the shock boot - perfect fit)

Falken RT660, 295/35 tires.

Fronts required extended studs and a 15mm spacer. They tuck in by 1/2".

This change was due to a new focus on handling. The tires are 200 tw and SCCA Solo (autocross) legal. They warm up quick and get sticky like a drag radial. I can't express to you guys how great they are. It's like having 555RII's for forward grip, but these handle and you have them up front too.

I've pulled a peak of 1.32 lateral g's on the autocross course so far. I have around 1500 miles on them and they should last around 10,000 total, but will likely age out before I get there.

How is your straight line traction holding up with those?

Nevermind, I glossed right over it. Need more caffeine. Thanks for the input on those!

Currently backordered, Apex sm10's 19x9 in Anthracite. Is 275 to wide for a 9" wheel? Better off going 265? When I get em I'll throw up a pic.

I believe a 275 is at the upper limit of a 9" wheel but should still be fine. You can check the specs of the exact tires you're going to buy- the manufacturer will list the min/max wheel width. If I were doing a 19X9 square setup, I'd definitely go with the 275s just to get a bit more meat on the rears. If you are going with a staggered setup with 10-11" rear wheels, I would do the 265s in the front. Just my two cents!

I've looked at a couple different charts and 275 seems to be the max width for a 9" wide wheel. Guess my question is, will maxed out effect sidewall strength and integrity? I don't want a stretched look to the side wall. I'm not racing just wanted lighter wheels and a bit more contact patch. I've scrolled back and there are members here running 275's on a 9" wide wheel. Thx for the advice.

I don’t believe there would be any issues from a sidewall strength or integrity perspective. Manufacturers are pretty conservative with their specifications. As far as appearance and fit goes- I think they would look just fine. I don’t think you’d notice much if any difference visually vs the 265. If anything, there could be a very slight bulge rather than “stretch”. You see some running very narrow tires on wider wheels, typically imports with wheels that “poke” beyond the fender, so they run a ton of camber and stretch the tires to prevent interference with the fender.

If you’re doing a square setup (same size front and rear), I personally think the 275 would be great. You’d get a little more contact patch and could still rotate the tires if you want them to last longer.

Sounds good I'll go 275, should give the car a whole new look, currently on 245/45/19's, they are actually the factory p zero nero's from Pirelli. 9 years old with plenty of tread depth left. Probably going with Nitto nt555 g2's, good all round summer tire imo. Thx again!
