The race gear box for your Elise / Exige or 2-Eleven !
Worn out synchronizer hubs, -rings or -clutches as well as broken gear wheels will be a thing of the past if using this transmission ! The gear is designed for a load up to 450 hp and 400 NM torque ! Boundaries are rather set by the weak basis of the original box.
Gear ratio data – gears 1-6:1. 3,002
2. 2,001
3. 1,502
4. 1,200
5. 1,001
6. 0,873 ; 6. gears with longer ratios are also available on request.
"final drive": 4,32 oder 4,62:1 oder 5,1:1
Included with delivery:
- Gears 1-6, incl. "final drive" and all shafts.- the shift forks which are made from high carbon steel are also included with delivery !
In addition we approve the utilisation of a non-suspended clutch plate made from sintered metal, which can be purchased from our company, too.
We recommend this race gear box only for "race or heavy trackday use".Since this transmission will be switched very fast, it is rather unsuited for "street use".Furthermore the shift-related noise is higher in comparison to the standard one.
The price only includes the "dog box kit", without assembly !
The gear box can be mounted to an available transmission housing at our workshop. (Pls. see selection)
Besides we offer the complete assembly to your vehicle, pls. contact us for questions belonging to prices and installation times.
Drexler Mechanical Limited Slip Differential
for Lotus Elise / Exige Mk1/2 with Rover 18K4-Engine / PG1-Transmission (Modelyear 1995-2004, manual)
Developed directly on track, the Drexler Mechanical Limited Slip Differential guarantees for a lot of driving fun and stands for a good workmanship! This Differential has been developed to optimize the requirements of the Lotus-Concept in terms of power-to-weight ratio, torque and driving dynamics. With the standard setting the lock is optimally applicable for track days, but still fine for road use.
The target is to achieve maximum agility and driving performance. The Mechanical Drexler Differential uses friction plates to generate the locking effect, thus ensuring effective operation of the Differential during acceleration, as well as an optimized braking effect. Precise handling is ensured by reducing the slip on the inside wheel and preventing "spinning" through the optimized force distribution on both wheels. Normally a friction-plates Differential works more efficiently than conventional parts using the Torsen principle or a Quaife.
The main advantages of a Mechanical Drexler Differential are:
- Improved acceleration skills through a fast and efficient locking response, especially from the cornerspeed and from the standing
- Improved traction and stabilization in the various dynamic driving conditions and driving styles (starting, accelerating, braking, cornering, high speeds, slippery roads)
- Durability is given by the use of high quality materials and high quality standards. Thus ensures a long service life and low revision costs.
Range: Elise Mk1, Elise Mk2 Rover, 111S (not Toyota-Powertrain), 340R, Exige Mk1
Quaife ATB Limited Slip Differential
for Lotus Elise Mk1, Mk2, VVC, 340R, Exige Mk1 with Rover 18K4-Engine / PG1-Transmission (Modelyear 1995-2011)
The popular upgrade variant for the OEM differential: The Quaife Limited Slip Differential!
A limited-slip differential provides you with optimized traction, sportier drive and improved braking performance of your Lotus. The Quaife Differential automatically biases the torque across the axle to the wheel with the most grip. Unwanted wheelspin and slip are greatly reduced, resulting in less understeer on front or four wheel drive machines and reduced oversteer on rear wheel drive vehicles. This is a performance benefit and increases the power output onto the asphalt.
In contrast to a Torsen-Differential the Quaife uses its own principle with helical gears. This keeps the temperature low and noises are quite low and quiet. Quaife never ‘locks,’ making it progressive, safe and user friendly. Also, this design ensures less material wear and thus for an extremely durable with low maintenance intensity. High reliability is further ensured by Quaife's precision workmanship, quality materials and ISO9001-2008 certification.
- Traction maximization and slip minimization through a controlled power transmission to the driven wheels (especially on slippery road conditions)
- Improved braking performance through reduced blocking, also working in conjunction with electronic stability and traction control programs
- Use of existing transmission oil specifications and less wear compared to a friction disc differential.
Clutch Master Cylinder
Besides the seals in the Clutch Slave Cylinder, the seals in the Clutch Master Cylinder will go over time.The Master cylinder is not a serviceable item, so you will have to completely replace the unit.
AP Clutch Slave Cylinder
The internal seals of the clutch slave cylinder on your car is being used quite intensively and unfortunately... it will start leaking at a certain point. The brakefluid will be exposed to air, which will increase the wear of the seal, but also the internals of the slave cylinder.When the cluch isn't engaging properly and certainly when you can see a trace of brakefluid coming from the cylinder, it's time for a change!This AP Racing cylinder is a direct replacement of the item on any car with a K-series engine. Simply undo the clip on the rod and remove two bolts, move the clutch pipe from the old to the new cylinder and off you go again!
Replaces the standard plastic clutch line of the early Elise models. Prevents the commonly known difficulties with the clutch when the engine is warm.Available for Elise MK1/MK2 and Exige MK1.
By the use of rubber bushings at the original switching unit, it can arise the formation of large tolerances. In order to obtain a more precise shift feel, it is recommended to replace the original bushings by Nylatron bushings.Assembly instructions are included with shipping.
