Got the tires delivered over the weekend. BFG had a $50 rebate that ended Friday. Discount Tire had an additional $50 discount (which just conveniently happened to cover their "free shipping" which just so happened to boost the price of each tire to match The Tire Rack's price with shipping). I got the BFG 275/40x17 sports.
The car rides nicely, handles great and there is no rubbing whatsoever. Year One definitely got the offset just right to fit the second gen F-body cars.
If I had it to do all over again, I'd probably get a taller tire like a 45 series, just to fill the wheelwells a bit more. The 275/40s are 25" tall, a 235/60x15 is 25.5" tall and a stock Polyglas F60x15 is 26".
Here is the before shot:
And the after shots:
