Just looking at different 7.5"/7.9" 4 pot calipers from different suppliers namely MiniSpares,MiniSport and KAD and there is a big difference in price but my questions are 1.Is there a big difference between 7.5" and 7.9" as regards stopping power bearing in mind that the system I will be using will have front/rear adjustable bias and solid discs.2.Are the KAD better than the Mini suppliers own brand.

IMHO Mini spares 7.9 vented, I have fitted all three types the Mini Sports ones are just junk and unsafe IMO,

there is No difference in the braking effort given by the KAD's over the Mini Spares,

Its also interesting to note None of the Miglia cars in the UK run KAD they all run Mini spars or WillWood,
regards,
Paul.

If you're going to the trouble of getting 4-pots, make sure you run vented discs...not solid ones!

I wouldn't think you'd need those on a road car, standard vented should be fine.
