Racing Brake Fluid Not all brake fluid is created equally. High
operating temperatures at the caliper transfers extreme heat through the piston
causing lesser quality brake fluid to boil. This in turn allows the fluid to become
compressed and reduces overall braking performance. The best way to
counter this from happening is to use a racing specification, mineral (never
synthetic) brake fluid and flush the system after each event for competition or
annually on performance street driven vehicles. Both AP550 and Wilwood 570
brake fluid is DOT approved with a dry boiling point of 550-570 degrees, low
viscosity minimizes aeration and permits easy bleeding.

Cosworth & Scorpio Rotors For those fortunate few who own
Cosworth Sierras or have converted XR4's to Cosworth type front or rear brakes
and are in need of replacement rotors we have them. Scorpio front or rear rotors
in standard and cross drilled are also available. (see price list page 31)
Cosworth Front 283 x 24mm standard, X-drilled, grooved
Cosworth Rear 273 x 10mm standard, X-drilled, grooved
Scorpio Front 260 x 24mm standard or X-drilled
Scorpio Rear 253 x 10mm standard or X-drilled
Performance Brake Kits Engineered competition brake kits for the
ultimate in stopping power.
pC Front R/S Brake Kit (283 x 24mm)
BAT R/S "big brake" kit allows larger 11.25" (285mm) brake rotors to be fitted
with standard XR calipers. Increasing rotor "swept area" in this way will greatly
improve stopping power (leverage) and help to reduce high brake temperatures
that can cause premature brake fade and poor pedal feel.
Kit includes:
285 x 24mm vented (standard or cross-drilled) rotors, Mintex 1144 brake pad
set, caliper mounting brackets & hardware (fitment with most 15" wheels -
some require slight modification)
kit supplied with standard rotors
M418
kit supplied with cross drilled rotors M418A
pD Front Brake Kit (283 x 24mm) w/4 Piston Calipers
Combine the performance of the R/S large rotor kit with 4 piston calipers for the
ultimate in stopping power.
includes: 283 x 24mm vented rotors,
4-piston alloy Wilwood Superlite 2A calipers with pads. (fitment with most 15"
wheels -some require modification or spacers)
M416W
pD Front Brake Kit (300 x 32mm) w/4 Piston Calipers
For those who are looking for the ultimate brake performance. Quite simply the
largest and most competent competition type brake kit that can be fitted to the XR4.
includes: 300 x 32mm vented rotors with light alloy hats, 4-piston alloy Wilwood
Superlite IIA calipers, caliper mounting brackets & hardware
M417A
(this kit also available for Scorpio ! ) G417A
Rear Kit (XR4 w/16" wheels) 300 x 21mm (See Price List)
includes: 300 x 21mm vented rotors with light alloy hats, 4-piston alloy Wilwood
Superlite 2A calipers, caliper mounting brackets & hardware
pE Wheel Bearings Genuine European Ford wheel bearing kits are
complete with all required service parts to do a first class job. Each kit
include bearings, races, seals and hub nuts to service one wheel.

The cooling system on the XR4Ti is fairly unique. If there is
another car with more individual hoses in the cooling system,
we have yet to see it. Compound this with the changes
throughout the model run and it gets even more complex. We
have a good inventory of the hoses and other cooling related
components that fit 1985-87 XR4Ti and some (where similar
or noted) for 88-1989 cars.

High Temp Fyre Sleeve The under hood temperatures on the XR4Ti can
be quite severe. Slipping a length of fyre sleeve over critical wiring or rubber water
& A/C hoses will add an extra degree of protection. Fyre Sleeve provides radiant heat
protection up to 800 degrees. Sleeve is sold per foot and is sized by internal diameter.
Hoses or wiring can be disconnected at one or both ends then slipped through fyre
sleeve or sleeve can be un-stitched at the seam and wire tied in place.

Engine Mount Insulators BAT has an alternative to the recently
discontinued original equipment Ford motor mounts on the XR4Ti. Simply
remove the old motor mount assemblies, discard the worn-out rubber
portion, and reuse the top and bottom metal plates with our replacement
insulators.
Note: slight modification requires 10mm holes in plates to be
increased to 12mm. Scorpio mounts are Ford mfg. direct replacements.

direct fit for automatic & manual Scorpio. A heavy duty version also available.
Note:
this "square" type mount can be fitted to the XR4 with special crossmember, (see
below) as the standard "round" trans. mount used on our XR4Ti's is no longer available.

pE Transmission Crossmember Wide and narrow type transmission
tunnel crossmenbers allow the above "square" mount/insulators to be installed in
the XR4Ti. Fitting the XR with this crossmember/mount combination is a consider-
able upgrade (strength, noise, vibration) over the USA supplied "round" mount.

pF Engine Belts H.D. Our search for the ultimate heavy duty engine
accessory v-belts lead us to the top cog "Gold Series" by Dayco. Top cog v-
belts are built to last up to 20% longer than conventional belts. A unique cogged
design increases flexibility and airflow around the belt for reduced friction and
heat. Laminated design with high temperature rated polyester cords provide
maximum tension holding (reduced slip) over the life of the belt.

Performance Ignition Wire Sets We have tried a number of
different ignition wire options on the 2.3 Turbo and 2.9L V6 engines and have
found the Magnecor brand to offer superior quality, performance, and durability.
Cables are red in color with 8mm, 8.5mm and 10mm cable diameters.
