Look under your MINI Cooper. Go ahead, we’ll wait….
See that little sway bar down there? Replace it with an ALTA
Performance sway bar and we promise better cornering, reduced
body roll and greater control over your suspension. ALTA Performance™
Sway Bars are bigger in diameter and come with multiple end-link
attachments, giving you more possible configurations than any other swaybar.
An important step to making your car turn better comes from
replacement of the rear sway bar. By increasing the diameter and
leverage, more cornering force is applied to the outside wheels. Thus
forcing the car to "turn-in" better. Additionally reducing sway also
increases the contact patch of the rear tires.
The Alta Performance™ rear sway bar goes one step
further than simply making the bar bigger. Although size is
increased, Alta has added the flexibility of changing the bars leverage
with 3 different end link attachment points. This allows the end
user to custom tailor the way his or her car handles.
The street enthusiast will enjoy a 19mm upgrade to improve cornering in ordinary driving conditions, others thinking of something a little more extreme, should look at the 22mm.
