i paid somewhere around 500 for the kit including shipping. this was for the non-e-brake kit. Install went good, there was a problem with my caliper mounting brackets, the threaded bosses for the slide pins were 1/2" but were supposed to be 1/4", instead of dealing with shipping i grinded them down myself. i called TSM a couple times, great customer service and super helpful. while i did the install, i also undercoated my fenders, replaced my axle seals and bearings, and painted everything with caliper paint to make it look pretty. after replacing a few brake lines, buying the kit, the above stuff and other randoms i was probably clocked in at around $700 total. i am very happy with the kit, looks great, performs alot better than stock.
worth the $700? some might not think so, but i like to spend my money, and my #1 pet peeve about these r/t's was that they had junk ass rear drums.
