They have full wedge adjustments on either side, ride heights, spring packers, air in the tires, not to mention original setups. they have so much more adjustments than back in the day it's funny. That doesn't even count what they have back at the shop and aero stuff. Ford was bragging about their multi million simulator they brought on line recently..I'm sure the others have something similar or are working on it.
