Anybody had any experience on Zimmerman cross drill brake disc? Is it worth the paying twice the amount for it. Or should I just stay with Balo. Or any other brand recomend. All the brake disc on my 1980SD is all worn out of limit. I heard from this board that brake disc worn fast on these car. Is it because is a heavy car? If that is the case I don't want to spend more money for the expensive cross drill disc and end replacing it latter. What do you guys think?l
