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 five possible configurations
The key 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 hard core street and track enthusiast will demand a 22mm upgrade to maximize cornering in all situations. If the 22mm bar is a bit extreme, check out the 19mm swaybar .
The ALTA performance Mini Cooper and Cooper S rear sway bar is a
great upgrade for your Mini. With the adjustability of our bar, and the
sizes we offer them in, anyone can find the perfect match for their
driving style. Below you will find a comparison of our swaybars vs. the
OEM part. Both 22mm and 19mm calculations are below. Please note all bars are made from 4140 Solid Steel, for maximum performance and lifetime durability.
Both 22mm and 19mm ALTA swaybars have 3 endlink settings per side. This allows for 6 possible setting combinations! Other possible settings may be had by combining different endlink connection settings from left and right endlinks. Below we have given the 3 main settings for each bar.
