Get the precise feel you need from your steering by eliminating the old OEM rubber bushing (guibo) from your steering column intermediate shaft to steering rack link. Unbolt the OEM parts holding the rubber disc and then simply bolt in the precision U-joint to eliminate sloppy steering, and increase response without the rubber backlash. Re-center the wheel when sliding over the splines and tighten set screws in the rack spline notch and the column shaft flat. Lower your BMW's unusually high steering wheel angle by spacing down the column 25mm towards the drivers knees and 12.5mm towards the firewall, using our aluminum spacers & replace the 4 point column mounting hardware with our M8x60 & M8x40mm included hardware.
