===S1 Elise Suspension Enhancement Kit===
[[Image:S1upgrade.jpg|thumb|right|S1 Upgrade Kit]]

In order that owners of S1 Elise might enjoy the benefits of suspension development on
the S2 model, a retrofit kit has been introduced which comprises Bilstein dampers and
Eibach springs to provide enhanced ride comfort and refinement.

Parts Required Part Number Qty

Suspension Enhancement Kit A111C0148S 1

comprising:

Spring/damper assembly front A117C0052F 2

Spring/damper assembly rear C117D0038F 2

Bracket, rear damper to chassis A117D0077F 2

Spreader Plate, rear damper mount A111D0125F 2

Fitting Instructions LSL459 1

Changes

The front spring rate has been increased to 42.5 N/mm from 27.5 ('Mk.1') and 35 ('Mk.2').

The rear spring rate has been increased to 50 N/mm from 40 (as 'Mk.2').

The front spring abutment uses the lowermost groove in the damper body.

The rear spring abutment uses the uppermost groove in the damper body.

The mid-laden (2 x 75kg passengers plus half tank of fuel) ride height is lowered to
130/130mm from 140/140 front/rear.

The brackets securing the rear damper to the chassis are unique to this application to
provide the correct mid-laden ride height (with other bracket variants, rear height would
be too low).

The spreader plates were fitted as standard to S1 cars with barrel shaped springs, but
not to parallel spring cars.

Apart from the mid-laden ride height, suspension geometry settings and steering rack
shim plates are unchanged.

Individual Part Numbers are

Bilstein Front Dampers E117.C.007H
Bilstein Rears Dampers E117.D.009H

===Elise 111R Sport Suspension===
[[Image:S2bilstein.jpg|thumb|left|S2 Bilsteins]]
{{clr}}
The suspension of the Elise 111R and Exige are similar, but the springs and dampers of the Exige are stiffened to match the Yokohama A048 tyres with wider front wheels, and provide a more sporting ride/handling balance.
Owners of Elise 111R who wish to enjoy this type of characteristic can fit the Exige springs and dampers in conjunction with a vehicle set of Yokohama A048 tyres mounted on Exige wheels.
The Exige front wheel size is increased in width over the 111R from 5.5J to 6.5J, and the front tyre section increases from 175/55 to 195/50. Rear wheel and tyre sizes remain unchanged at 7.5J and 215/45 respectively.
Tyre pressures remain at 1.8 bar front, and 2.0 bar rear.

Wheel options are either:

Standard Exige cast alloy, 8-paired spoke, satin black painted, front 6.5J x 16, rear 7.5J x 17

or:

Lightweight forged alloy, 7-split spoke, satin silver painted, front 6.5J x 16, rear 7.5J x 17
Each forged front wheel saves 2.4 kg over the cast Exige wheel, with a 2.7 kg saving for each rear wheel.

Note that using the wider wheel set and Yokohama A048 tyres on an otherwise standard car will
increase grip levels over the original specification, but in order to enjoy the full benefit of these tyres,
it is strongly recommended that only a complete vehicle set of wheels/tyres/springs/dampers are fitted.
It is also necessary to fit an edge finisher to the front wheelarches in order to maintain the legally required tread coverage when using the wider section front tyres.

Customers outside the U.K. should check the legality of this fitment with the appropriate authorities in their country of residence before purchase.

Part numbers are as follows:

Front Damper A122C0007H (2 required)

Front Spring A122C0008H (2 required)

Rear Damper A122D0008H (2 required)

Rear Spring A122D0006H (2 required)

===Nitron racing shocks===

Makers of after market shock absorbers ideal for the many track orientated cars
EG The Juno, the elise, exige, 340r from lotus, the new caparo T1, caterham and radical, claimed to give impressive results over OEM setups

NITRON shock absorbers combine outstanding performance with exquisite product design. Whether for road or track, on two wheels or four, NITRON have the suspension kit that offers fade free operation lap after lap.

The NTR has evolved from NITRONs fully adjustable race dampers, with developments being incorporated into the latest products. So as a result of the modular design, the top end components are included right throughout the Nitron range.

All NITRON shocks are gas monotube shim type with a high pressure gas charge. Couple this with a large piston area and an all alloy construction and you get an ultra low friction damper with excellent heat dissipation properties, ensuring total reliability and fade resistance.

Side mirrors

2007-04-11T10:42:38Z

Chopperver1: /* ELISE SIDE MIRRORS */

===ELISE SIDE MIRRORS===

The Elise S1,S2 and Exige including the new Europa all share the same side mirrors.

(340R was different)

They are parts bin refugees from the Rover days and were standard fitment on the Rover Mini Metro.

[[image:image1.jpg|thumb|left|Mirror Dis-assembled]]
{{clr}}
They are shared also with the MGF and MGTF and all the Vauxhall VX 220s. If you smash one then a breakers yard will probably be a good cheap source but you will have to get them body match sprayed which is prettty expensive for such a small job . The actual glass itself is about £25 each from Lotus. Occasionally on e-bay you can find singles or pairs of the whole assembly usualy under Rover or Metro. No Lotus Elise variant ever had electric mirrors or heated mirrors but some Rovers did as did some MGs so beware if you are buying from a breaker unless you really are a chav and a dab hand with electrics.

[[Image:sidemirror.jpg|thumb|left|Replacement Mulivex Mirror]]
{{clr}}
One other safety option is replacement glass from MultiVex. These are available in pairs and DIY bonded over your existing mirrors in a few minutes and are increasingly convex towards the ourtside and give a much wider field of view than the essentially flat standard fitment. They are particularly popular with trackday enthusiasts as they eliminate the notorious blind spot .Also useful on Motorways and when travelling abroad.

Organic Acid Technology

2006-12-05T17:22:49Z

Chopperver1:

'''Organic Acid Technology''' is a type of [[coolant]] used in the [[coolant system]] on internal combustion engines.

[[Category:Engine Cooling]]

For nearly a decade, vehicle manufacturers have been introducing and using a variety of extended-life coolants. The only thing these coolants have in common is that they all seem to differ in formulation and colour. There are orange, green, blue, red, yellow, even pink ones. The proliferation of different coolant types has created a great deal of chemical confusion about what type of coolant should be used to top off or refill late-model cooling systems.

Each vehicle manufacturer has their own unique coolant specifications based on corrosion protection requirements, service life and chemical compatibility. These requirements are usually spelled out in the vehicle owners manual, and/or a decal or label on the coolant reservoir. It is important to always use the coolant chemistry recommended in the vehicle owners manual.

YOU CANNOT GO BY THE COLOUR OF THE DYE in the coolant because two coolants with similar colours may have different chemistry, and two coolants with different colours may have similar chemistry. What is more, colours can change if somebody tops off the system with a different coolant.

COOLANT TYPES There are essentially three basic types of antifreeze:

Traditional blue UK/green N.A. antifreeze, the original universal formula that everybody used until the introduction of today's extended-life coolants. The is a fast-acting silicate and phosphate corrosion inhibitor, providing quick protection for bare iron and aluminium surfaces, thay have a proven track record of providing trouble-free service in virtually any vehicle application assuming the chemistry is correct. The short-lived nature of the corrosion inhibitors means this type of coolant should be changed frequently.

OAT-based extended-life coolants. OAT stands for Organic Acid Technology, and includes such ingredients as sebacate, 2-ethylhexanoic acid (2-EHA) and other organic acids, but no silicates or phosphates (except in the case of Toyota's pink extended-life coolant, which adds a dose of phosphate to its extended-life OAT-based antifreeze). OAT-based coolants are usually (but not always) dyed a different colour to distinguish them from traditional blue/ green antifreeze. GM OAT-based Dex-Cool is orange. Volkswagen/Audi uses a similar product that is dyed pink. But Honda has an extended-life OAT coolant that is dyed dark green and does not contain 2-EHA.

The corrosion inhibitors in OAT coolants are slower acting but much longer-lived than those in traditional coolants. Consequently, OAT coolants typically have longer a recommended service life.

OAT corrosion inhibitors provide excellent long-term protection for aluminium and cast iron, but may not be the best choice for older cooling systems that have copper/brass radiators and heater cores. It depends on the formula.

Hybrid OAT coolants, also known as G-05. This formulation also uses organic acids, but not 2-EHA (different organic acids are used). Hybrid OAT coolants add some silicate to provide quick-acting protection for aluminium surfaces. Silicate also helps repair surface erosion caused by cavitation in the water pump. Hybrid OAT coolants are currently used by many European vehicle manufacturers as well as Ford and Chrysler.

WHICH TYPE OF ANTIFREEZE?

The safe answer is the type specified by the vehicle manufacturer. But practically speaking, shops do not have the shelf space to stock different coolants for each different make of vehicle.

Many antifreeze suppliers have introduced Universal Coolant or Global Coolant products that are one-size-fits-all coolants CLAIMED to be compatible with ANY new vehicle cooling system as well as older vehicles.

One very important point to keep in mind here is that universal coolants and extended-life coolants are not lifetime coolants. The corrosion inhibitors in all types of coolant eventually wear out and must be replenished by changing the coolant. Leave the old coolant in too long and the cooling system will experience corrosion problems.
