arrutled and I both have 275's in back (though on different - wider - wheels than the stock 8.5" setup. They'll likely fit in there, but depending on where the stock wheels place the sidewalls, you may have to roll the fender or add a spacer. I'm leaning towards them juuuuust squeezing in there, or needing a fender roll.

I agree with others that you are risking tire bead separation by running that wide of a tire on an 8.5" wide wheel though. You'd almost need a cantilevered bead tire, which are not made in that size.

also these will be track(drag) tires only.... so iam gonna be running them on low pressure (should fix curve issues) and i will defenetly look out for these problems before i put them on the car..... also my car is stock hight... so taller tires shouldnt be a problem in anyway...

just give me a week and i'll tell you if they are good or not... i've done 265/35/18 on my 335i with no problem... so we'll see what happens with 275/35/18....
They will work for drag purposes, but from a handling, wear and grip perspective using rims that are too narrow may cause you to have less grip, worse handling and higher tyre wear compared with a narrower size of the same tyre that is a correct fitment for the rim.
