moton suspension ftw!
jk, i personally dont auto cross or take my sti killer to the track, but i opted for the ss b/c i want that adjustability. I would've opted for the ssp so i could get the edfc but i wasn't thinking lol but yea, i'd get the ss if i were you. its not like your gonna get new coilovers every month, so stick with ss. you wont regret it
