hehe adjustable price too i bet... :P
some people change to coilovers... some change to just the normal supra shocks (non tems) others just buy replacement tems (Tokico Illumina II i believe)
tems activates on hard cornering, hard braking & high speed... you can adjust to normal & sport... the only time you will see complete firm mode is when some of the previous happens...
i'm not sure of the sources in the US for lowering springs but i have seen alot of supra ppl mention Eibach (sp?)
the rear struts do exist... but hmmm dunno where hehe... maybe they also come up on ebay... just patience and looking i would think
