So I am planning on doing 350mm rotors with the stock calipers and caliper spacers on all four corners. My rear pads and rotors are worn and ready to be changed, so I was planning on adding the larger rotors to the rear now and doing the fronts when they are ready to be changed. I am assuming this will work fine and will not negatively effect brake bias since the stock calipers are still in use? Any thoughts would be appreciated.

here you go bud!

i hope this answered your question

it will not mess with brake bias since you are using stock calipers.

If he has 330s on the front and changes to 350s on the rear, it WILL change his brake bias as the braking force is applied further from the centre on the rear (more leverage). I would upgrade to 350s on all 4 corners, not just the rears.

On another note, does anyone know if the collapsible spare will clear the calipers with the spacers?
