Did some diameter and spedo variation calculations on the various wheel/tire options.
Rear wheel/tire (assuming spedo from rear wheel)
22" 315/30 29.441" 60.00 mph
21" 315/35 29.681" 59.51 mph
20" 305/40 29.606" 59.66 mph
19" 265/50 29.433" 60.02 mph
Anyone know if there is a coding option that specifies wheel/tire parameters?

Anyone have experience regarding paint vs. powder coating?

Body-shop says they clean and then use 2-pack paint. Powder coating shop says sandblast and then powder coat (spray and bake). Hope someone can offer advice/experience.
