wish i knew more about any of those tires. i have no experiance with any of them.
the yokos es 100s you mean the avs es 100's ? i have a set of those (just below street legal tread) I really loved them. good stiff side walls, i found them to have good wet traction (better then the RE070's ) . what i also liked about them is when you pushed them to their limits of traction, the grip didn't just fall off a cliff.
the Re070's feel more aggressive. however when i exceed their grip , it feels (to me) like their traction just falls off a damn cliff. if you manage to kick your rear end free with the RE070's it seemed like their traction was on/off. course i Only had those on for about 500 miles and then i switched to snow tires.
so no real seat time in my sti with them, so , wtf do i know.
Boot, Sperry posted (in a diff thread) he would prefer if some noob autoXers used less sticky tires. I'de actually like to use my AVS es 100's , but walmart refused to put them back on my last car (thread depth is just below legal) is there a place that won't really ... check / care ? i'de need them demounted and mounted on a diff set of rims is the issue.
do you happen to have an old set of something less sticky i could ride on ? if not i'll most likely be on the RE070's for the auto X. and only have maybe 500 miles on those tires... (probably not a great combo, noob autoXer and not in sync with the tires he's using) ...
