Get all 4 changed at the same time, it will completely change the car, you will have so much grip and no tramlining.
Good to see an honest assessment, we do see a few comments which are more towards the "I can get away with it". Too big a risk if we want high safety factors. We've only got 4 little contact patches with the road, we need the best we can get.
gIzzE's comment is so valid as well, BMW cars can be very sensitive to the tyre set. gIzzE's got a lot of experience, so he know's what he's talking about.
