Slammed to the ground by way of a KP six-link kit, McGaughy's drop spindles, and Firestone airbags, Justin left the suspension as it was back in '09, but with the new paint and new frontend, the black cast wheels were scrapped for something with more style. Enter Raceline, and their new Explosion billet wheel with intricate milling on each spoke. Each 26x10 billet hoop was polished to a mirror-like finish and wrapped in 305/30R26 Toyo Proxes ST-II tires for superior traction and protection. Upgrading the previous braking system, Justin stepped up to AP Racing/Stillen 14.25-inch rotors and six-piston calipers. Matching the red flames perfectly, the bright red AP calipers provide an impressive blend of performance and good looks.

Back inside the Sierra, each silver-painted panel was carefully reinstalled and the black leather seats were bolted in place. A 48-inch LED strip was installed at the base of the rear window to alert gawkers of Justin's braking and lane intentions. It's amazing how changing the cabin's colors from gold with airbrushed clowns on the dash to hot rod silver dressed up the interior and made it look higher-end. Continuing with the luxury theme, Bell Auto Upholstery, in Phoenix, covered the headliner in black suede.

Side by side, Justin's GMC and our Ram look like they could have rolled off a time machine transporter. Classic flames, big billets, and trick interiors are all nice on their own merit, but add to that the rumble of a 512hp V-8, and you have yourself a thing of beauty.
