Hi guys,

after just under a year of riding my new 575 (old carbon frame 2007) i find myself enjoying more DH riding and am contemplating changing it up a bit and slackening the head angle by 1.5` with a angled headset.
I have a L frame with 150mm rock shox sector forks (current angle 67.7)
has anyone done this and is it going to make any noticeably better ?

also i have elixir cr 9 brakes (F/R 203/180) and the rears are just doing my head in. have tried different pads, rotor cleaning bleeding... but still squeak and once they have been used for a couple of hours heavily just don`t work. Avid seems to blame certain frames for the noise issues (i have the upgraded rotors). anyone have a recommendation for a brake upgrade? thinking of magura marta`s or formula k24

cheers for the input
