Ok so Skyway pro brake fins can be bloody expensive & it can be difficult tracking them down.
This might have been posted before but I think i've come up with a solution (cosmetic at least) to save you from having to spend a fortune not to mention the time to hunt these little buggers down. be it for use on the Brake pad itself (or) for use as a ((((spacer/washer)))) to be used on a flat rear brake bridge which seems to be a common use for these things.
Cosmetically they look great & I honestly i can't see why this wouldn't work .
All you need are these from Wilko's, I think they were 89p a pack. The M6 30mm come in packs of 4 & the smaller washer come in 18's so for a full set of 4 brake pads you'll need one pack of these & 3 of the 30mm.
& layer them up
& there you have it (Et Voila)
