how do you figure out how much i need to clearance and how much i need in terms of the spacer.

the guys at the wheel place say i will need spacers because the offset of the wheels are et35 front and rear. but it is a staggered set up 8.5 in the front and 9.5 in the back for the new rims. how much room do i need to clear the 4 piston brakes?

they said for the clk 320 rims, the offset was in the mid 20s so i would need spacers. wondering how/what i need to calculate the spacer needed for the install. looking to do it down the road but collecting parts and info now.

Thanks
