Weeksy, I found the radial brembo conversion on the master cylinder to be much more benificial. been running standard sps cast iron discs anyhow but the feel at the lever and the progressive power is unbelievable with the brembo kit. If you've already got one then the discs would be the obvious option if not get the master cylinder, costs more performs better. Won't wear out like discs either unless you bin it !
