Not Ranked
Not on a Superformance but I ran them on the front of my NAF 289. Replaced an old set of Aldans. The QA-1 is a great shock that has numerous adjustments that can be setup for street or track. The adjustments really help to tune the suspension for varing track or road and ride/handling. FWIW
