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 differentials.
Being able to change gear as quickly as possible can make a big difference in time critical situations like drag racing and even track day racing.
The slowest component in any car is the driver and there is little that can be done to improve that. A quick shift kit will help to give you the competitive edge by enabling faster gear changes and allowing more ‘feel’ by reducing play. Read More...

Flywheel lightening and its impact on engine performance.
"No Fly(wheels) on us."
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. … Read More...

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. Read More...

Gearbox – Lower ratios give better acceleration times and lower fuel economy. Six or seven speed boxes are better matched to modern engines.
Most street applications are closer 1st and 2nd gear ratios for that off the line 0-60 boost or for the fast exec a lower 2nd and 3rd ratio give improved overtaking flexibility and 30 – 70 mph acceleration with a high 4th and 5th gear to give motorway fuel economy. Read More...
