I have 275 tires all around right now, but will be switching to 255 for my next set due to the moderate rub that has destroyed my front fender liners. This is a considerable factor given the huge reduction in push the car has with very wide front rubber.

I think the difference will be much more noticeable with narrow rubber, and with my winter 225 pilot alpins I am very excited to do some snow donuts in the car to experience the change.
This kinds of makes sense. On an Xi a whole lot less (as much as half) TQ goes to the rears, so you'd expect the LSD to not be as noticeable as on a RWD car.
