These are my new wheels Shelby CS1 . 20x11 rear and 20x9 front. Invo Nitto tires 295 , 255 . The tech that balanced these wheels put alot of effort into the balance.They are hard to balance due to the design. It is sad that the automotive industry is loosing him . He worked for the domestic auto industry for over 20 years. His car knowledge is extensive , it is the loss of a Master Technician .
