I bought Tom's rear upgrade in 2006, had it on for 3 years. Tom was great sending the kit quickly, especially sending the calipers ahead of the caliper cores. For the pre-ABS cars, this is one of the easiest and most effective brake upgrades. It's easy to put the calipers on, and they bolt exactly in the stock location. The extra rear brake is very usable on the street. Tom is also great at answering questions and helping out after the fact. More than a year after I bought and installed the kit, he sent me a new seal for the e-brake when it was sticking. That was without me even asking.
