Lastly comes the springs, shocks, and GM-style 10-inch rotors. Total Cost Involved has several different upgrades available. From rotor size, to chromed control arms and springs, and even billet shocks. We chose to use all the base components. After all, this truck is made to be a driver, not a show truck. We also chose to stick with the 10-inch rotors, as opposed to the bigger rotors, because the truck will feature OE-style 15-inch wheels. Anything bigger belongs on a Compton cruising Escalade.
