I disagree. tanabe has been doing coilovers longer than tein. the shocks are short stroke versions of honda oem factory equipment and are made by a supplier that makes shocks for honda factory cars. alot of thought went into the damping rates of the sustec kit. The tein ss isnt rebound adjustable which I think is a very important tuning element. the spring rates are quite soft. on the tein set. If you want to talk about the best I think Buddy Club is the best stuff out there.
