Performance transmission upgrades and modifications

“Low ratio gearboxes, slip diffs and performance gearboxes”

Setting up the transmission to maximise performance takes a lot of thought and planning.

We highlight the best mods and upgrades for your transmission with tips and instructions from industry professionals.

Getting the power from the engine to the wheels is the job of the transmission and this is an area where a lot of cars can lose power.

We look at the best Transmission mods from low ratio gearboxes, quick shift kits and slip diffs.

Converting a FWD to a RWD

We look at converting a front wheel drive car to rear wheel drive. Problems and shortcuts and suggestions for a FWD to RWD conversion project guide. For this reason, most high power cars and motorsport cars have a rear wheel drive setup. Even front engined street cars are converted with a mid mounted engine and rear wheel drive.

Cars are more fun to drive when the power is to the back wheels. It makes for lots of oversteer rather than the safer and more predictable understeer manufacturers build into FWD cars.


DMF vs solid flywheel conversions

We look at the benefits and disadvantages of solid flywheel conversions from a DMF and help you decide which is right for you.

It is our considered opinion that unless a car is used extensively for competition or off road you should stick with a DMF. The additional torque caused by tuning an engine or heavy competition use can quickly destroy a DMF. The solution would be to fit a stronger, higher performance DMF but the aftermarket industry seems geared up to offer solid ones as the upgrade option.


Lightening the flywheel

Lightening the flywheel – the flywheel works in a similar way to the wheel in the toy cars you used to rev up and release and let it zoom off. The heavy wheel located between the engine and the gearbox builds up rotational force with speed and momentum.

Effectively storing the energy and helping the car resist changes in engine speed – good for cruising at a steady speed but bad when you need a fast engine response.


Clutch tuning: performance clutch modifications and triple plate clutches setup

The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.

Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.
