[bmw13]

I have coils on the way... not just for stance or performance but both... I want the car to actually handle/ function better than it is/ does now, not just look better!

I am currently set up with 245 up front and 275 in rear. I did possibly want to go up to 265F and 285R. My questions are:

-should I size up or stay the same? (What will be best for handling/ cornering??) car is stage 2 power wise...
keep 245F275R?
or size up to 265F285R

-will I rub?
with what I have now?
or going larger in both front and rear

-do I need spacers?
with what I have now?
or is going up in tire size enough?
