I've been running this set up for almost four years. No problems yet. Can't imagine there would be. Make sure to flush fluids according to Mike Miller's recommendations in Roundel.

Flush coolant once every two years
K&N oiled cotton gauze filters, clean every 15,000 to 30,000 miles depending on icondition, use only K&N approved cleaner and oil, and follow K&N cleaning
procedures.
Interior Air Filter: Variable every 15,000 (if on all the time) to 30,000 miles

You're correct, but running a 275 rear starts to get a little tricky unless you get the offset of your wheels just about perfect. Otherwise you have to roll your fenders. That's why most folks go with a 265 rear, which works just fine with a 235 front, as it's still less than the 1% over difference (front to rear) BMW recommends.

What would the perfect offset be to run 275 in the rear with out rolling the fenders?

You should be fine if you're stock height, lowered you might need to roll your fenders a bit.

Also not all tires are the same size, for instance Falkens tend to run quite a bit narrower than Michelins. Look, there are TONS of guys running 275's out back, hell even 285's. You just have to be smart about it and get your fitment right, ESPECIALLY if you're lowered.

And fender rolling isn't a big deal. If it's done right you won't even know it's been done. I just wanted to make sure you were aware it was something else to consider if you're gonna run a 275 rear.
