pA Front Brake Special 260 x 24mm
This kit is just the thing for replacing the standard size, wear related,
front brake components. We supply high quality Euro specification
rotors and premium Mintex brake pads for either XR4 or Scorpio and
at a special price as compared to buying items separately.

BAT R/S Front Brake Kit (283 x 24mm) XR4ti
BAT R/S Brake Kit allows larger 11.25" (283mm) Cosworth 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. Kits are available in 4 different
component levels from as little as $295.00, which leaves you no
reason not to upgrade to larger brakes.
Kits include: 285 x 24mm
vented (standard or cross-drilled) rotors, Mintex brake pad set
(standard or M1144), caliper mounting brackets & hardware (fitment
with most 15" and larger wheels -some require modification or
spacers)
Front R/S Brake Kit (283 x 24mm) M417
includes standard rotors, standard Mintex pads, brackets & hardware
Front R/S Brake Kit (283 x 24mm) M417A
includes X-drilled rotors, standard Mintex pads, brackets & hardware
Front R/S Brake Kit (283 x 24mm) M418
includes standard rotors, M1144 Mintex pads, brackets & hardware

includes X-drilled rotors, M1144 Mintex pads, brackets & hardware
pC BAT/Wilwood Front Brake Kit (283 x 24mm) XR4ti
This kit combines the performance of the larger 283mm Cosworth rotor
with Wilwood 4 piston Superlite 2A calipers which are extremely ridged
and transfer torque directly without unwanted flex. Construction is
aluminum with stainless pistons for both weight savings and maximum
head dissipation. At just 5 lbs. they are also much lighter than stock
calipers. This goes a long way to reducing "unsprung" weight benefiting
both braking and handling performance.
Kit includes: 285 x 24mm
vented rotors, 4-piston alloy Wilwood Superlite IIA calipers with pads
and aeroquip brake hoses (fitment with most 15" and larger wheels -
some require modification or spacers)

BAT/Wilwood Front Brake Kit (300 x 24mm) XR4ti
This kit combines even larger 300mm Cosworth rotor with Wilwood
4 piston Billet Dynalite for the ultimate big brake kit. Calipers are
extremely ridged and transfer torque directly without unwanted
flex and are made from aluminum with stainless pistons for both
weight savings and maximum head dissipation. At just 4 lbs. they
are also much lighter than stock calipers. This goes a long way to
reducing "unsprung" weight benefiting both braking and handling
performance.
Kit includes: 300 x 24mm vented rotors , 4-piston
alloy Wilwood Billet Dynalite calipers with pads and aeroquip
brake hoses (fitment with some 15" & most 16" and larger wheels
-some require modification or spacers)

pA Constant Velocity Joints & Boots The Merkur XR4Ti and Scorpio
independent rear axle assemblys utilize half shafts that have inner and outer constant
velocity joints. Eventually these joints and protective boots will require service. We
have joints and boots available separately making it economical to replace just the
worn component without having to replace whole axle assembly. However, if more
than one C.V. per axle requires service, our complete axle assembly is the more cost
effictive way to go.
Note: right/left inboard and outboard C.V. joints and boots are
interchangeable- see price list for complete axle prices (handed left & right)

Rubber Drive Shaft Coupling The rubber "Drive Donut" or "Rotoflex
Coupling" on the XR4 and Scorpio drive shaft can be a real bugger. Many owners
have contacted us after being quoted up to 500.00 to totally replace the complete
drive shaft assembly by the local Ford L/M dealer, as they do NOT list the rubber
drive coupling as a separate service part. We import the proper replacement
drive coupling and make it available at considerable savings to you. If your car
exhibits a driveline shudder that increases with speed, (especially noticeable in
colder weather) we recommend taking a close look at the condition of the drive
coupling. Cracks in the rubber or missing pieces will require immediate replace-
ment, loosing one of these joints at speed will be very messy !
Note: BAT supplies
the standard equipment XR4i drive coupling by the original supplier to Ford. This
is not a lesser "fits all" component that just happens to be similar.

Quaife Torque Biasing Differential Quaife torque biasing
differentials provide a constant and infinitely variable output to both rear
wheels. These unique differentials utilize a series of helical gears which
sense the amount of applied torque and adjust automatically for loss of
traction. The Quaife limited slip design is also free of high wear items
(clutches, ratchets and plates), making them stronger and more maintenance
free than other types of limited slip units. Anyone who has had the pleasure
of driving a vehicle equipped with a Quaife LSD will immediately comment on
its smooth seamless performance, very unlike clutch/plate type LSD's which
exhibit a notchy ratchet like take up through the drive line. The Quaife LSD
that we offer is originally designed as a replacement upgrade for the Sierra
Cosworth and are now supplied with output flanges tapped for either the large
108mm (Cosworth size) or smaller 100mm (XR4 size) C.V. joints.

Clutch Kits We have a very good selection of clutch packages that include
clutch disk, pressure plate, throw out bearing, and clutch alignment tools. Buying one
of our engineered kits will guarantee best quality, performance, fitment (ease of
installation) and price. First option is a new (not rebuilt or re-lined) O.E. quality
replacement clutch kit by Sachs/Valeo. This clutch is best suited for standard or
slightly modified cars being used under normal driving conditions. If your requirements
are beyond the capabilities of the standard clutch we also have some heavy duty clutch
kit options. H.D. clutch kits include pressure plates that have increased clamping force
(from 30 to 50%) and clutch disks with high temperature friction materials applied.
Centerforce H.D. clutch kits have a unique centrifugal pressure plate design with
substantially more clamping force but requires very little pedal pressure over the stock
clutch.
Note: all kits are for standard transmission 1" 23 spline except where noted.
