I gave my brakes in my coupe a pounding last monday at wakefield and they are 200B GX 275 mm solid discs and alloy girlock calipers...never looked like fading...
If they do the job that you have for them, then they are a good thing. I guess that the weight is a little less too, & thats gotta be a bonus. As long as they work well, you're on a winner.
thats exactley the point if it works for you then go for it, As for weight difference yes they're a fair bit heavier I guess you cant have your cake and eat it as well here. it will be interesting to see how I go with pedal pressure. I have blue bird trx rear discs and i dont plan to run a booster, What master clyinder would you recomend to run??? any one?
