This Week At Quaife Engineering

Week 09


The QKE10R Quaife 6-Speed Sequential Gearkit for the Lotus Elise:

QKE10R delivers ultra-fast sequential gearshift technology for owners of Lotus Elise / Exige models using the PG1 gearbox. QKE10R features a replacement Quaife outer gearbox tailcase which houses six power loss minimising straight-cut, close-ratio gears and a compact, drum-style sequential gearchange mechanism. This combines with an open face dog design to ensure an ultra-rapid, positive sequential gear shift on QKE10R

QKE10R to retains the original PG1 bellhousing half of the transmission casing, plus the stock Lotus clutch, differential, driveshafts and mounting points. This enables easy installation of the QKE10R sequential gearkit into numerous Lotus models and potentially the MGF and MG ZR / ZS.

QKE10R is supplied with gear ratios suited to motorsport requirements and three final drive options to optimise top speed for the needs of competition.

Quaife ATB’s for BMW and Mercedes available at Kevin Bird Garages Ltd:

Did you know that there are over 30 Quaife ATB limited-slip differential applications to cover nearly all BMW models dating back to the 70s? All exclusively available at @birdsbmw.

Kevin Bird Garages Ltd stock an average of 750 Quaife limited-slip differentials which covers the vast majority of BMW and Mercedes models. Popular applications include; BMW E92 335i, BMW E82 135i, BMW E87 130i, BMW F30 335i, BMW F20 M135i and Mercedes C63 AMG.

We have completed the manufacture of QDF1Q differential bodies which are now ready for build:

Quaife ATB Helical LSD differential is suitable for a variety of models including the Porsche 911, and Porsche 924 Turbo models with 915 transmission (available with either 18 tooth spline, or 43 tooth spline to suit either)

A direct replacement for the standard open differential, the Quaife ATB Helical LSD differential transforms your car’s performance. Unlike a conventional plate-style limited slip differential, the QDF1Q Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The QDF1Q Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the QDF1Q Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
