Hi,

I have a 435 x drive gran coupe sitting on 400m staggered. Was wondering if I bought another pair of rear 400m (18x8.5 et 47) to run them up front for a squared set up if it'll clear.

if you put rears up front, the inside of the tire will contact the strut and/or spring perch due to the rear offset being ET47, which is too high. you will need at least a 10mm spacer to run the rears up front, a 12.5mm spacer being optimum.

here is a thread where it was done with 19" OEM rears, which are ET47 as well.
