Lotus Service Notes
2-ELEVEN.C - FRONT SUSPENSION
The front suspension is based on standard Elise/Exige componentry, but the angle of the top wishbone
ball joint housing differs to better suit the lowered ride height. For the same reason, re-configured steering
arms are fitted, being machined from solid EN16 steel billets, and heat treated.
On cars with the optional 'Sports Pack', revised road springs front and rear are fitted on Ohlins dampers
featuring remote gas reservoirs, adjustable spring platforms and separate adjustments for compression and
rebound damping. The 22 compression and 60 rebound damper settings allow the characteristics to be fine
tuned to individual requirements, whilst the threaded spring platforms allow adjustment of ride height and corner
weighting. Recommended front/rear mid-laden ride height for both road and track use is 100/110mm. Front
height should always lie within the range 95 - 110mm, with a corresponding rear setting 5 - 10mm higher.
Each gas reservoir is mounted on the side of the crash structure, and 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 counterclockwise 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 (included as part
of the Sport Pack) provides further opportunity
for fine tuning. To stiffen the bar, use a more
forward hole, and to soften, use a more rear-
ward hole. Recommended setting:
Road use: Central hole
Track use: Central hole
Note that the hard Nylon type chassis mountings used with this 'bar require periodic lubrication with MoS
grease at least every 3,000m (5,000km). For suspension geometry refer to Section 2-ELEVEN.TD - TECHNI-
CAL DATA.
2-ELEVEN.D - REAR SUSPENSION
On cars with the optional 'Sports Pack', revised road springs front and rear are fitted on Ohlins dampers
featuring remote gas reservoirs, adjustable spring platforms and separate adjustments for compression and re-
bound damping. Recommended front/rear mid-laden ride height for both road and track use is 100/110mm. Front
height should always lie within the range 95 - 110mm, with a corresponding rear setting 5 - 10mm higher.
The 22 compression and 60 rebound damper settings allow the characteristics to be fine tuned to individual
requirements. Each gas reservoir is mounted on the rear subframe and is connected to its damper body by a
steel braided hose.
