Drexler Mechanical Limited Slip Differential
for Lotus Elise 1ZR-/2ZR-Engine / EC60-Transmission (Modelyear 2011-onwards, 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: Lotus Elise 1.6 / Sport / Sprint (136 PS) und Elise Sport 220 / Sprint 220 / Cup 220 / Cup 250
Quaife ATB Limited Slip Differential
for Lotus Elise with Toyota 1ZR- and 2ZR-Engine / EC60-Transmission (Modellyear 2011-onwards)
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.
Range: Elise 1.6, Elise Sport 220, Elise Cup 220, Elise Cup 250 (1,8l with 136-250 hp)

1ZR- or 2ZR-Powertrain with EC60-Gearbox
The Elise of the 3 generation captivates with a balanced engine and sporty driving performance, unfortunately the gear ratio is extremely long. In order not to change the whole transmission gears, we get the final gear ratio swapped (crownwheel/pinion) so that all 6 gears become shorter, the dynamics of the car do very well. The standard gear ratio is 4.29: 1 and the optimized gear ratio is 4.93: 1
This conversion can optionally be combined with one of our limited slip differentials.
Ideal for sporty use or track day use.
The gear box has to be dismantelled and opened. A gear diagram is attached for illustrative purposes.
