i would say Ohlin's but there EXPENSIVE as ****.....Zeal I would say are probly the next best....then you have the under 2 grand but really nice coilovers, silkroad (my fav), tein (I dont like tien), Kei Office, Cusco....and so on, now on to the cheaper (under a grand) and still nice ones IMO, Megan Racing, and D2's there a couple more I think and if you include ground control as full coilovers?
Now a good set-up for the drifting we do and still drift on the street would be 8-6 and 8-7 for S14s.
I like 6-4 really good for daily and still nice on the track and drift....I HATE coilovers that have like 36way adj....good for track racing but not for the street.
Someone else can take it for the mono tube and blah blah......
