AST makes high quality products and I have had very good experience having my STi suspension rebuilt for reasonable prices.

I had this exact setup on my STi as well. I recognize your username from back in the day.

I can also vouch for the AST damper quality. I tracked my STi a good bit, though not in competition, and the dampers were quite enjoyable. They held up to the elements well also, in case anyone is wondering.
