Koni dampers with Exige specific springs, and the uprated front anti-roll bar in Nylon chassis mounting blocks.
The standard setting for the front anti-roll bar is the central of 5 available holes. Steering rack positioning
plates from the Sport kit are used to suit the specified mid-laden ride height of 112/122 mm, which differs from
other sport variants due to the increased wheel diameter. Standard Elise suspension links and hub carriers are
used.
