I've got the RacingBrake BBK installed on my '08 TSX and they require 5mm spacers with the OEM wheels. Without the spacers, they're way too close - maybe 0.1mm of clearance at best, with it slightly scraping paint off of the caliper. I purchased a set of four spacers from Motorsport Tech - 5 x 114.3, 64.1mm hub diameter and they're a spot-on fit. Keep in mind you'll be giving up 5mm of lug nut to wheel stud thread engagement, but everyone I've asked said for 5mm and under spacers, the OEM studs are fine - without the spacers, you have 15mm of lug nut to stud engagement, so with the spacers, you're down to 10mm.So, I have read everything that I can find on the matter and what I am finding is that these are able to fit stock OEM wheels.
Can anyone confirm this?
