Suspension Packages -XR4
Below is a listing of shock and spring packages available as engineered
suspension packages. Fixed rate or adjustable shocks are supplied as noted.
More information on the shocks that make up these kits is listed elsewhere in
the front and rear suspension sections. Kits are available with either -25mm
or standard ride height sport springs- your choice same price !
Spax Sport Gas Shocks & Sport Springs (-25mm or Standard) M400S
* supplied with fixed rate high performance gas shocks
Bilstein Gas Shocks & Sport Springs (-25mm or Standard) M400B
* supplied with fixed rate high performance gas shocks
Spax Sport Adjust Shocks & Sport Springs (-25mm or Std.) M400A
* supplied with adjustable high performance gas shocks
pB Sport Spring Sets -XR4
Our specially designed progressive rate sport springs will minimize body "roll" while
cornering and reduce "dive" under hard braking. Progressive springs are designed to
become stiffer as they are compressed allowing for a smooth transition between (very
reasonable) straight line comfort and high performance cornering. We recommend
the standard height or -25mm ride height sets for all around performance street and
light competition use, the -40mm springs should be considered for only racing/
competition use. Take into account when lowering your cars ride height that additional
negative camber will be added to the front and rear suspension angles. This is usually
not a problem on the front end, however, cars that are already experiencing noticeable
wear on the inside edges of the rear tires at "standard" ride height will see this increase
when lowering. This condition can be corrected if necessary by using camber shims
(kit available below) at the rear spindle mount to adjust for excessive negative camber.
Notes: Defining "standard" ride height is difficult on the XR4 as the springs on many
cars have already "sagged" 1/2 to 3/4 of an inch since new. In this case if the front
and rear tires are still wearing normally lowering the car another 1/4" or 1/2" (over what
it is currently) should not adversely effect tire wear.

pC Rear Camber Shim Kit -XR4
To correct rear camber angles on cars that have excessive negative camber
we offer a handy rear spindle shim kit. This kit is sometimes necessary on cars
with lowered sport springs, but can also be used to correct camber on cars with
"sagging" stock rear springs. The components (instructions and shims)
needed to space the rear bearing spindles between the brake backing plates
are supplied. This camber kit will add roughly 1.5 degrees of positive camber
and adjust rear toe back with in standard range as well.M423R

Front Strut Tower Brace -XR4
The XR4 has a well built chassis structure that does not exhibit much flex
under normal conditions. With the addition of high performance tires and
suspension parts more stress is put on the front strut towers causing some
deflection under hard cornering which will eventually weaken the structure
and lead to unpredictable handling characteristics. Connecting the front strut
towers by adding a upper stressbar (strut tie bar) will improve chassis
stiffness and keep the suspension angles constant under hard use condi-
tions. For this purpose we offer a lightweight aluminum front tower brace
(stressbar) that incorporates a removable tubular cross brace and cast alloy
turret mounts. Highly recommended for cars that are used for track events,
drivers schools, auto-cross and spirited road use.M403F

Rear Shock Mount Brace XR4
Our rear (stressbar) is a nicely finished lightweight tubular aluminum rear
brace which is just the thing for linking left and right hand upper shock mounts.
A slight bit of plastic trimming is required when fitting. Bars are supplied with
an attractive blue finish.M403R
