So I've been researching a factory brake upgrade for my car and I came across an old post on the "other" forum that mentioned the use of Celica All-Trac calipers on our cars. They mentioned that they bolted right up without any modification, but i can't find any info to back it up. Is this true? Or is he completely off his rocker and that's why it's never mentioned again? My other thought was that he was describing the Previa minivan caliper "upgrade" (2piston vs. 1). If anybody has any info on this I would appreciate it.
