I recently replaced my Cobra brakes with the Brembo's, and I'm glad I did. Brake pads are significantly easier to swap, the caliper is stiffer and has much better fade resistance. I beat the snot out of these things at Gingerman a couple weeks ago, and they never even came CLOSE to fading. I literally metled my inside rear pads after 3 sessions, but the front's held up great.
