well some of the reasons poeple are up set with TRD
is the fact that they make many other performance parts for other cars such as the camey, corolla, etc. and also the fact that their parts are way over priced.
I think one the main reasons that TRD
has not made so many engine parts for our cars is becuase the celica was not designed to be a straight line specialist, they do make Suspension parts becuase if you haven't noticed the celica is a cornering machine. so far we have a rear strut bar, coilovers, sway bars, etc. availible to us. Our engines and ECU don't even react well with mods anyhow and i think that TRD
already realized that. And the reason that their parts are so expensive is becuase of the warrenty on them and the fact that they will not void your cars warrenty
