These were Twin Cam roadsters with bolt on aluminum hardtops for lightness. The body tonneau aft of the seats was slightly modified to allow stowage of a specified size piece of luggage as required by newly revised rules pertaining to production based sports cars. The folding convertible top was also deleted for the same reason. These five cars were ultimately to be the only Twin Cam roadsters on record with hardtop installed by the factory, and the only MGA roadsters to leave the factory without a convertible top. The light on top was to let the pit crew know the driver intended to pit on the next lap. The switch was located on the top of the dash. The lights were different color for each car so the crew could tell them apart in the dark.

From the beginning of the M.G. Car Company in the late 1920's through the early 1960's the MG factory was regularly in the habit of building and sponsoring production based cars for competition as a way of demonstrating the strength and durability of the cars. 1960 was the only year that the factory built Twin Cam MGA roadsters for the Sebring race in Florida. Five virtually identical Twin Cam competition cars were prepared at that time, four of which went to Sebring for the endurance race on March 26, 1960, and one to an importer in Canada (never to be raced at Sebring). One of the Florida cars was to be a practice car, being substantially flogged by all of the team drivers in the days prior to start of the Sebring endurance race. Only three of the cars were run in the official competition. All of these cars were to be painted green with black interior and were fitted with hardtop, 4.55:1 final drive ratio and close ratio gearbox. The engines were close to stock except for being fitted with 2 inch carburetors in place of otherwise standard 1-3/4 inch carbs.
