Where the RSi was converted to RHD for the UK market, there is a bar running from your brake pedal across the bulkhead to the servo on the left side of the engine bay, over time the plastic bushes get worn and sloppy

2wd cossie brakes do fit with the right conversion brackets, as do 4x4 calipers, i have gone for S2 Turbo calipers and 2wd cossie discs
