Our 06-0031 disc brake kit (elsewhere) has been a great success and we now offer an alternative version with Wilwood forged alloy calipers in place of the original-style Dunlop calipers. This results in a greater pad swept area and a further reduction in un-sprung weight. It's also quite a bit less expensive. Key to the kit is our newly developed braided stainless steel brake flex-lines, they allow for a totally bolt-on conversion that's completely reversible any time you wish. Kit includes splined wheel hubs, rotors, calipers, caliper mounting brackets, braided stainless flex lines (we even include a new rear line) and all hardware. For all XK-120 and XK-140 with wire wheels. Not for XK-150. This kit will not show as being in stock but no worries; it is assembled from individual pieces when ordered.
