We're building this car to have awesome drivability, and we wanted to use components that could stand up to some occasional punishment. It's no secret that the Currie 9+ rear axle systems are up to the challenge. We already had the Boyd's Junk Yard Dog wheels and Nitto 555 tires, so we worked backwards and fit the rear axle to the car and wheels. In this case, we used a custom narrowed Currie housing loaded with a Nodular iron center section, 3.25:1 gears, a Detroit Truetrac differential, and 31 spline Currie axles. The Truetrac is a nice piece because it offers smooth, quiet operation, and locks automatically when needed. Once it was painted and installed, we added a Baer Track 13" rear disc brake kit. In front, we again used a Baer Track kit with 13" rotors and dual piston calipers for awesome stopping power. An Eastwood powder coated CPP master cylinder and stainless brake lines from Classic Industries round out the system.
