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

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.

Engine Components
Utilizing a design similar to the earlier German
2000 OHC "Pinto" engine the 2300 "Lima" en-
gine eventually replaced the 2000 OHC in most
North American Ford 4 cylinder vehicles from
1974 on. Built for lower maintenance with the
addition of hydraulic lash
adjusters the 2300
was designed to
operate in a lower
RPM range using
its larger displace-
ment and in-
creased torque to
its best advan-
tage. Perfor-
mance turbo-
charged versions
of the 2300 began
to appear in 1979 in
the Mustang/Capri and continued through the
80's in a more refined and powerfull EFI turbo
version. A reduced bore 2000 displacement
"Ranger" truck engine (from 1983-87) was also
produced. Some late production "Lima" engines
are equipped with hydraulic roller cam and valve
train, and other versions use dual spark plug
cylinder heads. The 2300 is a fairly rugged
engine in its stock form, however some compo-
nents will require up-rating with performance
components if high RPM duty is required. The
"Lima" series turbo and normally aspirated en-
gines respond quite well with a bit of perfor-
mance tuning and though lacking in refinement
do give quite a bit of bang for the buck.

Transmission & Related Components
pHShifter- A serious short throw competition gear lever
featuring a robust large diameter shaft placed within a
spherical bearing. The all metal construction will cause
additional transmitted noise but this is a small penalty to
pay against the strength, speed and quality of the gear
change achieved. M717
pIGear Oil- Torco synthetic gear oil is designed to
withstand tremendous heat and provide extreme anti-
score protection under high torque "shock loading"
conditions. That is why most Indy car and drag race teams
rely on Torco protection. Torco SAE 75w90 gear oil is GL-
6 rated and includes limited slip additives. Great for both
transmission and differential applications. Torco synthetic
gear oil greatly improves the shift "feel" of T9 transmission,
shifting becomes light and precise, almost like a tune-up in
a bottle. Notes: transmission will require 2 quarts (2.25 to
3.34 pint capacity depending on year) and rear axle 1 quart
(1.6 pint capacity) Gear oil not for T5 transmissions (use
ATF type fluid). C2S
pJQuadrant & Pawl Kit- When the clutch pedal "ratchet
adjuster" wears out it contributes to poor pedal feel and an
annoying clicking noise. Renewing the quadrant and pawl with
this handy kit will alleviate the problem. M368
pK Rebuilt T9 Transmissions- Highest quality factory
certified remanufactured T9 transmissions with European
gear ratios (3.65:1, 1.97:1, 1.37:1, 1.00:1, 0.82:1). M700

pG Short Shift Kit- If anything can be added to enhance
the "link" between driver and transmission while rowing through
the gears on the XR4 or Scorpio 5-speed this is it. We have a
dynamite quick shift kit that fits standard T9 Hummer transmis-
sions. If you like the shifter "feel" on Hurst equipped Mustang
GT, this kit offers similar results. Customers often remark that
this shift kit is one of the best modifications that they have made
to their cars, especially considering the price and ease of
installation. Just think about how many gear changes you make
in a day, let alone a week, or year. Shouldn't every shift be quick,
light and precise? M715

The Ford Type 9 (T9) or Hummer transmission is a 5-speed version/
conversion (an overdrive portion is added in a casting extension
behind the main case) of the venerable Type E 4-speed. The only
problem with this transmission is the 2.3 turbo engine's torque output
is near the top of T9's performance envelope. It would seem that
Ford's choice of manual and automatic transmissions were both
marginal at best for use in the XR4Ti. Even so the T9 can give better
than average service when driven sensibly. However, they do not
fair well when abused! A sure sign of problems is a "growling" input
shaft bearing. The sooner this is attended to the better. When the
input bearing fails it will take with it some, or all, of the gearing making
for an expensive repair bill. We can supply individual T9 replacement
parts from this list as requested.pNSyncronizer Ring- 1st/2nd gear M711$33.25
