I've always wanted to try the Tanabe Sustec Pro 7 for the DC5 ......... I'm not sure on the pricing though, I heard Tanabe recently has an authorised dealer in Sunway area.
Tein's super street, i suspect, is too soft for hard cornering. I don't think there's much improvement over the stock suspensions which are already pretty stiff, only benefit the super street has is height adjustable (but it affects the spring rate, it's not individually adjustable)
Tanabe and Tein has many similarities for entry level suspensions.
both damping rates are electronically adjustable ,
Tein = EDFC
Tanabe = TEAS
if you're on a tight budget , why don't you check out GAB? It's made locally, so should be cheaper.
but always keep in mind, you get what you pay for. better stuff always commands a premium price.
