Marc wants efficient braking for an eventual 190+bhp. He want to know if uprated discs (20groove) uprated pads, lines and dot 5.1 are gonna be good enough for that. The other option is twin pots (ae111, ae101) but he doesnt like the effort/cost involved in sourcing the parts, longer wheel studs, resized rotors etc, want its outta the box. I told him it would be very worth it to go for the twinpots for a better (+ more powerful) solution, to match the performance. The uprated route is very good and sufficient but you can do much better i.e the twinpots being an upgrade I would class as stage 2 braking, the latter being stage 1. Joz
