Great coilover for street and track/autocross. A little stiffer springs than the ST Coilovers but not as stiff as the BC Racing. This has great adjustable shocks too, like the BC, except the BC is a monotube and these are twin-tube (like Konis) so they have a bit more comfy feel on the street.
So, if you like the idea of the ST coilover, but you want a touch more spring rate and adjustable shocks but you don't want go with a full coilover like the BC (with camber plates), this is your kit! :) The fact that this retains the stock upper front strut bearing and mount is one reason it is more street worthy.
Spring rates are listed in Tein documentation as 336/448, but we dyno'd the springs at 330/410... so the rear springs seemed to be a little bit softer than advertised... not a bad thing frankly.... we tested the Street Advance on our own car drove and it handle exceptionally well but was still decent as a true daily driver. I would highly recommend this to anyone wanting adjustable shocks and a medium-stiff but very street-able spring rate. Very Koni-like with springs that are more or less a bulls-eye on where we think they ought to be for a fun but decently comfy street car. Note that the shock adjustment is quite progressive... meaning out of 28 click, the first 14 don't do too much. But once you get to 21, you are about 50% of the way to full stiff. 25 clicks is about 75%. Then 28 clicks is full stiff.... so you see, most of the damping adjustment happens above 14 clicks.

The Tein Street Basis is the exact same kit as the Street Advance, except the Advance has adjustable shocks.
