Great quality shocks, these shocks have a great build quality and finish. They come in kit form with clear instructions and can be built with either 2 or 3 hole pistons depending on your set up. They took around an hour to build all 4 and all parts went together well with no problems. Once fitted to the car (M03L) they showed a instant improvement over the standard shocks and the car was much more controled through corners with less roll. Overall a top quality product for a great price.
