question out of curiosity, why would you chuck away the twin piston calipres on the xt130 struts and i dare say downgrade to ra60 calipres?
i have ra60 struts and brakes on my car, and the braking ability of the ra60 calipre is absolutely nothing to rant and rave about let alone justify rebuilding them.
im sure you have a reasons behind running such a set up, maybe there is somthing for me to learn
