Best help I can offer is that on my MR2 I'm running 350 / 450. Of course, that's at 2370# plus.

From my old (1990) TRD catalog, and as best as I can decipher the codes (they don't really give rates on the springs for that model) the TRD "race" fronts were ~260 and the rears ~220.

Now, for the silly question . . .. When did they readmit the 80-83 TE's to ITB? The earlier and later ones with the 2TC / 3TC were ITC, and the '87 with the 4AF as well as the 4AG-powered FWD FX (AE82/89) are ITB. Did they just leave it out of the GCR (I know they USED to be IT? Was it a FasTrack thing, or is it just your area?
