Positive Steering Response System
The ALTA PSRS replaces the front
control arms, rear rubber bushing with a solid type spherical
bearing. Improving the handling characteristics of your
MINI Cooper and enhancing your performance
driving.
What Is The ALTA
PSRS
The ALTA PSRS replaces the front control
arms rear rubber bushings with solid spherical bearings. The solid
design of the PSRS will not allow any wheel deflection
under heavy braking or acceleration, in turn your
MINIs suspension geometry will not change making the
vehicle handling more consistent and predictable. Under
acceleration your MINI will have more front end
traction and be more predictable in corners. Wheel hop will
disappear and your MINI will feel more stable. Under
braking steering feedback issues and wandering are eliminated!
OEM Bushings vs The
PSRS
The OEM MINI bushings are made of soft
rubber to reduce noise, vibration and harshness (NVH),
and make the ride more comfortable, in turn this creates a large
amount of wheel movement under braking, accelerating and cornering.
For the performance minded MINI owner, this creates
unwanted movement, suspension mis-alignment, and changes in
handling characteristics of your MINI. The solid
design of the PSRS eliminates suspension misalignment
making your MINI handle consistently and predictably
during all driving conditions including extreme driving.
Caster Changes and Their Effects
By offsetting the center pivot of the ALTA
PSRS allows the installer to add between 0 to 1.5
degrees of caster to the front suspension. Adding caster will give
your MINI better directional stability when traveling
in a straight line such as the highway or interstate and reduces
its tendency to wander. MINIs with wider aftermarket
wheels and tires, will find they will no longer be as effected by
uneven or rutted pavement.
Excessive caster angles can make the steering feel heavier and less
responsive, but in a MINI by adding a small amount of
caster will have little to no effect on the amount of effort it
takes to turn your steering wheel. All the while gaining you a
tremendous improvement in handling as detailed above.
Outlasts the OEM Bushings
Replacing your OEM bushings before a complete failure
is great preventative maintenance and a good way to enhance your
cars handing. The OEM bushings are constantly being
twisted as your control arm moves up and down. Over time the rubber
hardens and begins to crack. The ALTA
PSRS with its special urethane bushings will outlast
the OEM bushings for years of performance driving.
