I would love to have 275 or 285 rear tires.
I am planning to add some power so I will need as much grip as possible.

If you're keeping the stock fender width 265 would be the max you could go. Sure the rear at 275 may seem like more rubber but the amount of camber you would have to dial in would mean much less of an actual contact patch. 275's CAN fit. But you need the perfect offset. Take a wheel off and get in there with a tape measure.
The front, can't manage more than 245 imho, just not enough room in that wheel well.
