Notes
- Shim distribution at the front bush of either wishbone must be copied at the rear bush of that wishbone.
- Transferring a 1.5mm shim washer from ahead of, to behind the pivot bushes, will reduce castor by ap-
proximately 0.4°.
- Transferring a 1.5mm shim washer from behind, to ahead of the pivot bushes, will increase castor by
approximately 0.4°.
- Ensure that the load spreading washers are correctly located beneath the bolt heads and nuts as shown
in the drawings.
- Ensure that the pivot bolts are tightened only with the vehicle at ride height. Torque to 45 Nm.
CI.3 - ANTI-ROLL BAR
Three types of anti-roll bar and chassis mounting have been used:
1. The standard tubular steel anti-roll bar is mounted in pivot bushes onto the front face of the chassis, and
is linked to the outboard ends of each lower front wishbone via short ball jointed links. The bar is mounted
to the chassis using rubber pivot bushes for noise isolation, retained by alloy clamp brackets. Washers
welded to the bar bear against the inner sides of the bushes to provide lateral location of the bar. Castrol
LMX rubber grease, or equivalent, should be used when fitting the rubber bushes onto the anti-roll bar.
2. On Elise and Exige models built with 'Super Sport' suspension prior to August '06, a stiffer adjustable bar
is used with 5 holes in each end to allow some adjustment of roll stiffness to be made. Standard setting is
centre hole. Using a more forward hole increases stiffness. Two hard plastic clamping blocks secure the
bar to the chassis via the front lower wishbone inboard front pivot bolts, with 'top hat' section steel spacers
preventing the clamps from being crushed. An M5 bolt is used to close the bottom of each clamp.
