Screw adjustable Watt’s linkage kits
For the ultimate in fine tuning of live axle rear roll centre.
Race Products’ screw adjustable Watt’s linkage kit is the ultimate in fine roll centre tuning with ease. In this universal kit, the roll centre adjustment is carried out in seconds by twisting the threaded shaft from the boot area allowing adjustment in 1mm increments.
As with our peg adjustable kit, the body mounted bell crank allows for easier adjustments and gives a more consistent roll centre compared to an axle housing mounted setup.
These packages have proved very popular across all forms of motorsport, including Sports Sedans, Touring Car Masters, Improved Production, Nc Touring Cars, and Speedway. It’s an ideal way to fine tune your suspension, and in conjunction with one of our Race Products camber kits, it’s the best way to gain an improvement in outright lap speed for your racecar.
Our screw-adjustable Watt’s linkage kits are available in three heights, offering a range of body brackets from 325mm tall to as low as 200mm, suitable for cars with very low boot floors or ride height.. The towers however can be supplied either right hand low/left hand high or left hand low/right hand high, depending on things like exhaust system placement in the vehicle and in a variety of different tube sizes.
