A quick way to verify mileage is by inspecting the drum brake shoes on the unit. The drum pulls straight out, off the axle. Rear shoes are never really replaced until about 60-100K miles unless there was severe duty (read abuse) placed on the car.

    Maintenance Check the items on the race car check sheet in the Appendix on a yearly basis or before track days depending on how hard the car is driven. Wheels  Only 7”-9” wheels are recommended for the front. If using a wheel wider than 7”, FFR front lower control arms are needed to prevent the wheels rubbing the control arms.

If you would like a wider tire than this in the rear it is possible to use aftermarket 10.5” wide, 27mm offset wheels if the axles and caliper brackets are changed so that the rear is the same width as the 87-93 rear ends.

    Gears The Mustang 5.0 manual transmission car comes with either 2.73 or 3.08 rear end gear ratios from the factory. If you can get a rear from an automatic car it will have 3.27 gears. There is an ID tag on the rear differential.

    In order to increase the flow of air above 5000 rpm, upgrade from the stock mass air sensor. Aftermarket 70 mm or 75 mm mass air units are an excellent choice and have proven effective. If the mass air meter is changed make sure it is calibrated for the injectors you are using or you will have to change the injectors too.

  • Page 486: Oil Cooler

    Timing Most computer chips simply change the timing of the engine and slightly enrich the mixture. Using a timing light, advancing the base timing to 14 will do the same. Higher octane fuel will be needed. Under-drive Pulleys Yes. They work well on all cars. Oil Cooler Not really necessary on small blocks or cars that aren’t raced heavily.

    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.

  • Page 488: Rear Suspension

    FFR two piece spindles (FFR#14850) – 5 lug, many wheels and brakes plus improved suspension geometry, improved steering feel and more adjustability over 94-04 spindles. Rear Suspension The standard solid axle 4-link rear suspension works well, is low maintenance and is reliable. Which rear suspension you choose depends on the type of driving you do a majority of the time.

  • Page 489: Control Arms

    3-link suspension - This is for the more serious driver that goes to more road course track events and wants to start exploring the limit without giving up the “off the line” bite of a solid axle. IRS suspension – Good everyday driving suspension. The IRS is best for rough surfaces Control Arms Stock: Stamped steel with rubber bushings.

  • Page 490

    Front: The stock front arms work well all round. The Factory Five tubular lower control arms with polyurethane bushings are lighter, eliminate the rubber and look better than the stock Mustang arms. Rear: Using tubular control arms with polyurethane bushings helps to locate the solid axle and hook up better on the drag launches.

  • Page 491: Shocks/springs

    Shocks/Springs Using the Mustang rear coil springs and shocks gives a comfortable ride. For a slightly stiffer suspension, replace the stock rear shocks with aftermarket units. We have found that KYB makes an inexpensive good replacement that roughly 20% stiffer than stock. For the well balanced fun to drive car, the 3-link rear suspension combined with the Factory Five custom valved Koni rear coil-over shocks work the best.

    Rotate the differential until you see the small bolt (Differential pinion shaft locking bolt) that holds in the large center pin. Remove the bolt using an 8mm socket and ratchet. Reach behind the differential and push out the center pin from the back side. www.factoryfive.com 508-291-3443...

  • Page 524

    Once the pin is removed, push the axles in toward the differential. When you do this the C -clips that hold the axles in will be visible and they may even fall out. If the C-clips do not fall out, push them off with a small screw driver or needle nose pliers.

     Caution: Care should be taken not to damage inner wheel bearing oil seals when removing axle shafts from rear axle housing. Install the brake caliper brackets so that the caliper will mount on the front side of the axle. Use the four ”-16 flange bolts provided and torque them to 45-50 ft/lbs.

  • Page 526

    Slide the axles back into the differential and re-install the C-clips. When re-installing the C-clips it helps to use a small magnet to hold onto them as it is difficult to reach the axle and hold onto the clip.  Caution: Care must be taken not to let axle shaft splines damage inner wheel bearing oil seals or rear wheel bearing assembly.

  • Page 527

    Once the C-clips are in, pull the axle back out until it stops so the clips are held in place. Install the center pin and the bolt that holds it. It’s a good idea to put Locktite on the bolt before installing it, then torque it to 25 ft/lbs.

    Install the brake rotor using one lug nut to hold it in place. Make sure to clean the surface of the rotor with brake parts cleaner before installing the caliper. Once the rotor is on, put the brake pads in the caliper by pushing down on the pad to compress the wire springs on the top of the pad, and then slide them into the slots in the caliper hanger.
