‘Fine Tune’ diff cams or more precise adjustment of the belt tension. The ‘low position’ diff cams lower the diff by up to 1.5mm below the original kit diffs. This re-positioning of the diffs will give the car more ‘side bite’ giving the car a more positive feel all the way through a corner. Includes 1 pair of diff cams that can be used in the front or rear of the car. You will need to make some small modifications to the middle of the toe blocks and the chassis which requires a rotary tool and cutting or grinding wheel attachment. Please see fitting guides.
