Why not a square 305 setup on Base GT350?

[1mic]

Not sure why you would want to run 10.5s when you can easily run 11 all around.

Probably because enkei only makes the sizes they specified. Your best bet is going another brand, but if you look at the chart, the other brands are 3-4lbs heavier.
If you want lighter weight you are going to have to pay $$$.

Besides, 10.5 can fit 315s. And OP is asking about a square 305 setup.
10.5 all around on 305s.

I run 295 on my rear 10.5" MPSS tires, 20" rim.

I decided to go with Forgestar 19x11, 56mm offset on all four corners with 29mm spacers on the front. I'll be running 305/30/19 for the track, probably NT-01s.

Spacers? On the track? Is that ok?

Yeah I would look at another brand vs downsizing. The factory 305 comes on a 11" wide rim, I personally would not go any lower than that. You can actually give up contact patch when you pinch a tire onto a smaller width rim. Always better to stretch it a tad vs the other way when it comes to performance cars.

BBS does not offer a wheel for GT350 or R as of yet.
they do have cars listed on website.

Yes. And I say that as a mechanical engineer who as actually looked into it, not repeating what I found on the internet. Since the spacer is just returning the aftermarket wheel to the stock wheel offset, there is no additional load put into the stock hub and studs. The spacer has to be hub-centric though.

I've been searching for an American company to make the spacers with American-sourced material, but haven't found one yet. Some will use American-sourced 6061-T6 aluminum but use no-name, made in China studs. Unfortunately, ARP doesn't make a 14mmx 1.5mm stud either. So I'm still hunting.

For those of you that have tried the EVO2 hankooks, yes they are worse than the pilot super sports, but would they be better than the OEM pirelli crap that is on the normal GT's with PP?

No.

PZeros are not exactly a bad tire. They're just not worth the $350 - 400 you generally pay per tire. They actually stick rather well but can be finicky at the limit and let go abruptly.

I agree with you on the spacers and ARP is going to make the studs in S550 fitment and should be available early next year.
