NOTE - DO NOT mix up the alloy mounting block/clamp pieces, as they are matched pairs.

This bar has been developed to complement those road cars fitted with post 1990 rubber springs. Being the softest compound yet used on the Mini in an attempt to improve comfort, they allow more body-roll. This bar will not only reduce body-roll, but also slightly reduce dive under braking and squat under acceleration. The bar is aimed at the general daily driver. For more progressive drivers it is highly recommended that its used in conjunction with rear anti-roll bar kit C-AJJ4009. By testing various settings its possible to attain a very well balanced fast road car with improved steering response to compliment the other advantages of these bars. It is made to only fit the standard diameter/dimensioned tie-rods To fit it will be necessary to place the car on either suitable car ramps or vehicle lift that raises whole car on its wheels. The reason being the bar needs to be fitted with the car sitting at normal road going stance. The bar’s lever arms are angled to closely duplicate the tie-rod attitudes compared to the front of the subframe.

The active (centre) part of the bar is designed to fit across the front of the gearbox, and just behind the subframe front cross member. Loosely assemble the bar to the tie rods using the relevant clamps and 2 off 5/6”UNC x ¾” cap-bolts positioned about half way along the tie-rods. The clamps have a shaped hole and a straight hole. The straight hole clamps to the tie-rod, the other around the bar. They are shaped to allow a small amount of movement to compensate for geometry angle differences in operation. Position the bar to chassis mounts one at each end of the bar’s centre section just before the bends that form the lever arms, and with the deepest piece between the bar and subframe. The mountings fit against the flat area of the subframe close to where the side beams and front cross member over-lap. Tighten up the bar-to-tie-rod clamps a little, until the bar is suspended in place, held away from the front subframe by the mounting blocks. Carefully position the blocks until the centre bar section is as close to the tie-rod to subframe mounting brackets as possible without actually touching them, and the bar is as symmetrically positioned as possible. Place the outer pieces of the mounting blocks to their relevant mate in place, then clamp the whole assembly to the subframe. Now remove the bar to tie rod clamps, allowing the bar to swing down. Check that it rotates freely.

Carefully mark the subframe through the mounting block retaining bolt holes, remove the blocks and bar and drill all four holes 5/16”/8mm. Re-assemble the blocks and bar in position, and fix in place with 4 off 2 ½” x 5/16”UNF bolts and 4 off 5/16”UNF Nyloc nuts. Again check for free rotation of the bar in the blocks. Some slight re-angling of the subframe may be necessary as these areas vary from subframe to subframe - not always being flat in all planes. Ease subframe where the mounts are bolted to until the bar moves freely. Then re-assemble bar to tie-rods using the clamps. Start with the clamps nearest the hub end of the tie-rods for minimum effect. Sliding the clamps forwards increases the bar’s effect. Always make sure the clamps are the same distance along the bar measured from the forward, angled end.

Importation rules regarding vehicles are very specific: Only those over 25 years in age may be brought in to the USA without compilance to Federal Motor Vehicle Safety Standards (FMVSS).
