Hi there
Looking at some compbrake pro race 5 calipers
They will be on my type R and used for spirited driving and track day here and there ( if we ever get the sun )
The reviews I have read online seem to be related to the older pro race 4 and had some mixed reviews .

I know AP obv the first choice but I am limited budget of £450 so not an optic. Sadly

Any info would be good
