Has anyone ever run a 275 tire on a 4th gen?

Has anyone ever run a 275 tire on a 4th gen?
I'm still trying to figure out offsets and what would work on my car, but before I get ahead of myself I should ask about tire fitment.
I'm going to be running in the DSP class in SCCA Solo auto-x next year, and need to fattest tire available to be competitive. I'm going to run the Hoosier A6 on a 17" wheel, and the two sizes that are available (and useful) are 245/40/17 and 275/40/17. I would either get 17x8" or 17x9" wheels to put them on.
I already had my rear fenders rolled, and am not sure if rolling the front fenders is an option, and if it is, how necessary it would be to run a 275/40/17 tire.
I will be on coilovers with about a 1" drop all around, and since these will be track-only tires I won't ever turn full lock with them. The most I anticipate turning the wheel would be 1 full turn in either direction, so I would have 1/2 turn of unused lock on either side (3 turns to lock rack).
So it basically boils down to this: can I run a 17x9" wheel all around with 275/40/17 tires? I'm going to be getting Enkei RPF1s, which have offsets as low as +22 available, which is what I assume I would need to clear such a wide tire, although I'm probably still not understanding offsets properly.
Any help would be greatly appreciated!

cool story OP
there was a 4th gen i seen with 17x9 or 10 all around with 275-40-17 tires had a lil poke up front but it looked ok.
offset 22 is a lil bit aggressive and would push the wheel out nearly flush with fender imo
over here in Cali people are wheel ****** haha ive seen a few sets of rpf1's for sale if i come across a set in 17x9 w/ 22 offset ill ask em if i can test fit them and snap a pic of clearance

From talking to people at Hoosier and other racing folks, it sounds like the idea size is going to be a 17x8.5 with something around a +30 offset. However, that might not clear my Wilwood BBK, so I might have to drop down to the +22. It sounds like the 245 Hoosier should be more than enough tire for what I need, so chances are I'm going to go with that. I just need to figure out what offset will clear the BBK now.....

i think a 30 will clear. my friend has a wilwood bbk with 18x8 or 18x8.5 +38 or +43 or something around that but it clears barely and when we test fit my 18x9.5 +35 wheel it would not clear the bbk unless we ran like a 8-10mm spacer and i believe my wheel design was the cause of it not clearing

I've run 17x9 +34s with 275/40 victoracers and 17x10 +35 275/40 hankook Z214s
17x9s with victos
17x10s I road tested this setup but never tracked it.
Since you are looking at RPF1s this is a 17x8.5 +40 front with a 255/40, 17x9.5 +38 rear 275/40 street tires, perfect fit.
the +40 has lots of room for big calipers
My car was on AGXs and Stechs, no camber plates. Rears were rolled and I never had an issue with the fronts.

So I was mistaken about the available offsets for the 17x8.5" RPF1. Apparently there's only a +30 and a +40. To be on the safe side, wouldn't the +30 have more clearance for calipers than the +40, or do I have it backwards?
The last question would now be whether I go with regular silver or the nice polished finish on the RPF1.....
