Yes I already searched for this. Anybody know of a somewhat inexpensive caliper upgrade for the TC rear disc setup? I just upgraded to the 73mm front calipers and its much better now, just wondering if there is a rear upgrade available. Iknow the 93 cobra is a similar setup, and they show diff part#s for the cobra and the TC. MB those would work.......BTW I have the SVO mc and proper 2-3 port conv with the prop valve.
