The fronts are 19x11" +24 with 305/30-19 PS4S. Again GT350R specs. I don't know if they'd clear your narrower GT fenders.
I am having Anderson composite CF vented and wider front fenders being installed now. But I do not have a need to go wider than 285. Thanks for your help.

If you're going 325 or 345 out back you'll want to go wider up front or thr car will understeer terribly while cornering due to the grip imbalance. If you're only concerned about straight line performance then that's an entirely different set of concerns.

While those rear tires may be labeled as "345", they are one of if not the narrowest 345s ever. There's very little if any bulge on the sidewall, almost as much as a 305-315 tire.

I have a set of Michelin 325s on 11" wheels and they bulge more than that.

While I guess it's cool to be able to say you have 345s on the back, you probably get more tire with a 315-325 from other brands.
I ran 325s on an 11 inch wheel. They bulged a lot.

285/35 on 19/10 front and 325/30 on 19/11 rear.

Well that is a conundrum, I do like race and slide around corners. I guess 305 up front would be better and track accordanly with the rear 325.

My guess is small diameter wheels (look like 18s) with tall tire exentuantes the bulge. With bigger wheels and a smaller sidewall, it's not as pronounced. I have a tire that runs pretty wide to begin with on 11" wheels and they don't bulge anywhere near like yours.

A 345 would really be swollen on the rear. Here's mine with a 325 PS4S on the rear. Fits the wheel perfectly.

Wow that looks good. What diffuser is that?
