just wondering what size wheels you need to clear the brakes on the front of a focus rs.
reason im asking is because i want to put sum smaller wheels on the front with some slicks/semi slicks for rwyb days

 

ive got a set of 17oz suoer t's i use for trackdays. offset is important to clear the caliper

 

i believe 8 x 17" is the smallest alloy you can get on the FRS but iirc these only just clear the front brembo calipers with very little clearance but offset, etc has to be spot on to do so

TBH most FRS owners who have done track/rwyb have stuck with the standard 18" wheels

 

17" wont make a noticable difference IMO

 

my others are 7 17
only reason i use 17's on trackdays are for the bit more rubber
