NO point I sold my braided goodridge hoses on here and stuck bog standard hoses on my Shimano brakes, which I had in the spares box! I got 30 quid back on my brakes and they worked the same. I enjoyed the night out with the money a lot more than someone saying "ooooooo you have braided hoses made by goodridge" I don't like the look of them anyway, trying to be a bit too motocross IMO. I never really noticed a difference on my motocross bikes when I once put some on. Since that it sort of put me against them Ha.
As for the discs well they are supposed to spread the heat over the entire disc better and dispel the heat better. Again I have XTR discs on my bike which are floating. the other bike as the same disc brakes but with a more standard less fancy Shimano rotor and the brakes don't feel as good with the floating rotors on.
The answer is NO, you don't need these at all! If you were Steve Peat then maybe they might be of some use for the ever and I mean ever so slight difference they would make to someone of that level. Plus he would get them for nowt too!
