Why are the SSTB brake calipers cast iron instead of aluminum like my Envoy?
Are they any bigger ?
I would think that they would be pretty heavy on the front end and was thinking about buying a set of stock Envoy calipers made by PBR and mounting them on if there was no fit problems with this. Any one Know or have any info on this?
Thanks:thumbsup:

From what I understand they don't flex as much under a serious load, which is a plus considering the weight of the truck, the speeds it can achieve, and what it can tow.
