Not necessarily…Megan has made some great strides in product quality, and are inching thier way up in hte pecking order, but they have a long way to go.
For a WRX, there isn’t much better off-the-shelf that Cusco Zero2-R, for that chassis. It is a well documented steup for time attack and such, I don’t know what your exact goals or budget are, but I’d avoid anything Tein, except for the super high-end ones. It’s true they are adjustable, but a large percentage of the adjustment does nothing, and the ones that are aren’t particularly repeatable (which is something most japanese susp manufacturers appear to be guilty of.)
