Product I wouldn't test again.
Thorley Headers for a 3RZ. They make good stuff, just not for the 3RZ. Evil Government and those pesky smog req's.
ORS Suspension. Mike and the guys at that shop are/were freaking wonderfull. VERY VERY Good people. But the kit was lacking a bit from a design standpoint. Very much status quo.
Bumpers and rocker guards. No one makes good ones. (In my opinion) I want tougher stuff.
