Before you get lowering springs , I would definitely look into a set of Vorshlag Camber Plates ( site sponsor ) because you really need some negative camber up front for turn in and extra tire life on track , just to name a few benefits. Also for crisp shifting check out the website www.mgwltd.com for the absolute best short throw shift kit on the market for the MT-82 transmission. It is the gold standard and well worth the extra over other systems. Have fun researching things for your beautiful Boss, but never hesitate to ask questions or request help ---- everyone here is quite friendly and willing to assist. The big question we all have for Trackrats in BC is whether they have gotten to run at Area 27?
