High Horsepower Transmissions
Stock: T-5
The stock T-5 is good for the stock 302 engine. If the engine is going to have some work done to it then
an upgrade to a heavy duty, Ford Racing “Z” T-5 is all that is needed. An additional change to a Tremec
TKO 500 or 600 is needed if the engine that will be used has 350lbft of torque or more. One unique
feature of the Tremec TKO is it allows the shifter to be relocated 8” forward of the normal shifter
location if a vertical shifter is desired verses a forward angled shifter.
Steering Rack
Stock: 15:1
Once the car is rolling either a 15:1 or 18:1 rack will yield about the same effort feel. This is good for
most driving situations. We have found that many of the Challenge Car racers prefer to use power
steering. This can be done by using the stock 1987-1993 15:1 Mustang power rack and power steering
pump. If changing to a manual 18:1 rack, a universal joint with a different number of splines will be
necessary in order to connect the steering shaft to the steering rack. Factory Five offers a 18:1 manual
rack and the correct splined adapter for it.
Spindles

geometry, improved steering feel and more adjustability over 94-04 spindles.
