Lotus Service Notes
EXIGE S/C.C - FRONT SUSPENSION - 240R & CUP
Stiffened road springs front and rear are fitted on new Ohlins dampers featuring remote gas reservoirs,
adjustable spring platforms and separate adjustments for compression and rebound damping. The spring plat-
forms allow for lowering of the car to 120/120mm mid-laden ride height for track use, and the 22 compression
and 60 rebound damper settings allow the characteristics to be fine tuned to individual requirements. The gas
reservoir is mounted on the inboard crossbrace of the lower wishbone, and is connected to the damper body
by a steel braided hose.
Compression (bump) damping is adjusted by turning the knob on the end of the gas reservoir canister: Turn
clockwise to increase damping, and couterclockwise to decrease. Recommended settings are as follows:
Road use: 11 clicks from full hard
Track use: 11 clicks from full hard
Rebound damping is adjusted via a ribbed collar below the bottom spring seat: Turn clockwise (as viewed
from below) to increase damping, and counterclockwise to decrease. Recommended settings are as follows:
Road use: 8 clicks from full hard
Track use: 8 clicks from full hard
The motorsport stiffened and 5-position adjustable front anti-roll bar provides further opportunity for fine
tuning. To stiffen the bar, use a more forward hole, and to soften, use a more rearward hole. Recommeded
setting:
Road use: Central hole
Track use: Central hole
Suspension geometry is unchanged - refer to Section TDQ.
EXIGE S/C.D - REAR SUSPENSION - 240R & CUP
Stiffened road springs front and rear are fitted on new Ohlins dampers featuring remote gas reservoirs,
adjustable spring platforms and separate adjustments for compression and rebound damping. The spring
platforms allow for lowering of the car to 120/120mm mid-laden ride height for track use, and the 22 compres-
sion and 60 rebound damper settings allow the characteristics to be fine tuned to individual requirements. On
240R models the gas reservoirs are mounted on the roll over bar backstays, and on Cup cars, on the toe-links.
Each reservoir is connected to its damper body by a steel braided hose.
Compression (bump) damping is adjusted by turning the knob on the end of the gas reservoir canister: Turn
clockwise to increase damping, and couterclockwise to decrease. Recommended settings are as follows:
Road use: 15 clicks from full hard
Track use: 10 clicks from full hard
Rebound damping is adjusted via a ribbed collar below the bottom spring seat: Turn clockwise (as viewed
from below) to increase damping, and counterclockwise to decrease. Recommended settings are as follows:
Road use: 15 clicks from full hard
Track use: 12 clicks from full hard
Suspension geometry is unchanged - refer to Section TDQ. The Track Use Chassis Rear Brace Kit is
fitted as detailed in sub-section DH.5.
EXIGE S/C.E - ENGINE
The 1.8 litre 2ZZ-GE engine with VVTL-i (Variable Valve Timing and Lift - intelligent) of the standard Exige
is fitted with a low pressure Roots type Magnuson MP62 supercharger to provide up to 0.5 bar (7 psi) of boost
pressure. The supercharger is mounted on the left hand side of the block and driven by a lengthened version
of the multirib auxiliary belt. The unit is self contained and features helix twisted rotors to minimise output
pressure variations, and maintenance free gearing and bearings, requiring no externally sourced lubrication.
An integral by pass valve under ECU control, operates to recirculate air from the compressor outlet back to the
inlet under conditions of idle and part throttle to the benefit of economy and quiet operation.
The supercharger is hung off the new intake manifold by two bolts in conjunction with eccentric sleeves in
order to ensure stress free alignment. An alloy bracket supports the nose of the unit to the RH engine mounting
plinth, and a tubular strut braces the intake end of the unit to the clutch slave cylinder mounting point.
