I had the TEIN S techs and every time I'd turn they would pop out of the seat. So I switched to EIBACH sportlines and love em. They ride nice and handle great. GO with the Sportlines.

I have an 02 Si.

 

i have them too and think they're great...but a bit bouncy...
i switched over from the GC Coilvers which also had a seating problem...
they GC's were EXTREMELY noisy...
i guess coilovers are not the way to go on the ep unless you're willing to drop a few grand on a real nice set...
