Diggity graphite shock towers front and rear (same positions as stock but are great looking and very strong)

I ran J Concepts Bar Codes front and rear with stock white foam and worked all day with little to no tire wear. Pinks BK Bars Rears with the Pink 7206 ribs or Pink Tapers for front are what most run at are track and also proven to work well. I would start with your local tire of choice and traction compound.
