one set left on the SSR, the fronts need a spacer to clear the non brembo brakes, with brembos, you'll need a bigger spacer, but it may make fitment too aggressive. The rears could use a spacer to be more flush. It's a wacky size, hence the cheap price.

So what size spacers do you recommend for the front and rear?

 

10mm for fronts to clear caliper. Rears do not require a spacer
