Lite-Weight -- 1983 Mustang Coupe (Notchback)
Log #005 Winter, 2004
PROJECT LITEWEIGHT GETS HEAVY!
The center section or pumpkin contains the differential, in this case a spool, along with a 4.56 ring & pinion. It was purchased from Rich Demarco as he will be stepping up his parts from a 31 to 40 spline setup. (see future Hot Street article). The axles are 5-lug and the Moser housing is a bit shorter than the standard 8.8 Mustang housing which aids in tire and rim selection. Although the emphasis of this project is to build an ultra lightweight vehicle, we felt the use of a 9 inch rear is just good old fashioned muscle car necessity. The 8.8 rear requires several modifications once you start going faster. C-clip eliminators (positive axle retention) is a necessity and are not to be used with disc brakes. Project lite is also using a Willwood lightweight rear disc brake setup, hopefully offsetting some of the girth added by this rear end setup.
Complete Engine Assembly.
Although project lite has gotten a bit heavy, it has all been done in the name of safety and durability. The combination will still be on the lighter side of most late model mustangs out there. See ya on the scales!
