Fits Toyota E153 transmissions found in:
91-95 MR2 Turbo (and 95-99 overseas models)
87-89 MR2 SC
Camry V6 (speed sensor for Camry does NOT fit with this differential! If you need speed sensor you’ll need sensor and sensor ring from 91-95 MR2 Turbo non-LSD. Also, custom axles may be required)
MR2 Type (LSD or non-LSD) axle stubs will work.
If you need a functioning vehicle speed sensor you need the VSS gear from the non-LSD MR2 transmission (mfg discontinued)
This differential is MWR’s choice for all street and most track applications.
- No noise
- Relatively easy install
- Never wears out, lifetime guarantee against wear and breakage
- No adjustments needed
- smooth engagement
- No special oil needed
- Better and more predictable turn-in
The only reason to choose a clutch type differential over a torsen (Quaife) type differential is if you frequently get a drive wheel up in the air, such as in rally racing or when bouncing over large curb sections on road courses.
- If installing in an E153 transmission originally equipped with the factory LSD and you need a functional vehicle speed sensor you’ll need an MR2 non-LSD VSS gear (not needed for most cars with ABS- if your old transmission didn’t have one, you don’t need it. MK2 MR2 DOES need it.)
- New differential bearings and axle seals are strongly recommended for this install. This kit is available through MWR separately.
The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How? By getting the power to the ground! The Quaife Differential powers both drive wheels under nearly all conditions instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.In drag-race style, straight-line acceleration runs, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential (they don’t call open diffs “peglegs” for nothing).
In cornering, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.
The Quaife also controls loss of traction when the wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs. The Quaife’s unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.
The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement. The Quaife is great for street driving or racing. Racers don’t have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it’s there until pushing the car’s limits.
The Quaife has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become “required” equipment for a winning effort.
Every Quaife ATB Differential comes with something else other’s don’t have: a Limited Lifetime Warranty. This warranty applies even when raced !
