Nah, the ST170 brakes will do fine for a while. Much better than what you have and a lot of ppl underestimate the ST170 brakes....good little setup them.
Had mine on for a good while, never let me down on track days and all. But I have AP Racing 4 pots to go on instead...a tad better than anything else out there, except Alcon!
