Welcome to the forum, Riley. I believe there is a Wilwood solution for front brakes that will fit with the 13" Lotus road wheels. Search the forum for threads on brakes, lots of good info scattered around there. There is not an 'off the shelf' brake assembly with integral parking brake from Wilwood, etc, that will fit the 13" wheel, though there was a forum member working on modifying a Wilwood assembly for this application, that may see the light of day. The problems were significant, but reportedly not insurmountable. Stay posted to the forum, as brake discussions occur from time to time.
