nice car mate,i have the tanabe sustec pro's on my ek4 sir, the car handles **** hot,although my ek4 is not as low as your 9,i also have the sustec strut brace same as yours,was thinking about taking them off and putting them on my 9,but my ek9 has'nt done many miles so the standard stuff should still be all good,i am in two minds also,standard or the tanabes???,for the record i find tein stuff too track orientated for road use (i had them on my last 9 not sure what ones flex etc) whereas these tanabes were designed for street use,i'm sure if you muck around with the settings you will get it handling properly.
