Mael, still interested in my brakes? Yeah you don't need Hydraulic brakes for DJ/Street. Just overkill. Someone mentioned hopes m4/m6 (don't remember, too lazy to look) Definalty no! Overkill to the third power. I have the Mags and they are much better then the Nines. Get avid mechs. 8" front 6" rear or dual 6". No need for dual 8". I ride DH with 8" front 6" rear. Its enough trust me.
