ok, lets put it this way, most of the feed back iv had on springs iv sold say their cars were lowered 27-30mm.
i have yet to have anyone say it was only 20mm.
like most companys TRD has to be careful, if thy say it WILL lower EVERY car 30mm, they open them selves up for problems. hence the wide range.
not one person has come to me to say TRD springs are crap and dont perfrom as advertised.
that help?
FYI, my ae101 (non s/s) hasnt had any weight loss and it was bang on a 30mm drop
