For a car of such diminutive proportions, the Mini certainly left a lasting impression on the world of motorsport. From its famous rally victories on the snow-covered slopes of Monte Carlo, to the David vs Goliath battles with vehicles twice its size in the British Saloon Car Championship, the bite-sized Brit tended to punch well above its weight.
One driver with first hand experience of the Mini's sporting prowess was Ralph Broad, whose success racing the car in the late 1950s and early '60s led to him founding a team of his own: the creatively named Broadspeed. By 1965 the outfit's success had seen it become the official works team of BMC Mini in the European Touring Car Championship, taking the chequered flag in its class at circuits including Spa, Monza and Zandvoort on behalf of the brand.
Despite his success with the standard Cooper S, in 1966 Broad made the switch to racing Fords, and at the same time began work on his own significantly redesigned incarnation of the Mini. In its most thoroughly reworked form, the Broadspeed GT 2+2, as it was dubbed, featured a new interior, adjustable suspension, rear anti-roll bar and twin fuel tanks. It also received a tuned engine with a reworked cylinder head, a custom camshaft, re-contoured combustion chambers, a 10.5 to 1 compression ratio and a modified inlet manifold.
It also, of course, sported an entirely redesigned rear end. Crafted from fibreglass it was significantly more streamlined than the standard car's boxy behind. It did somewhat restrict access to the boot, though (in that it completely eliminated it) so fold-down rear seats were included, through which a storage space could still be reached.
Compared to today's Spotted, however, the 28 examples of the 2+2 which saw production before the factory was demolished in 1968 are positively common. Only one race-prepped GTS was ever made. That car, the one for sale here, had a claimed top speed of 140mph thanks to significant weight saving achieved though lightweight magnesium-alloy wheels, a lightened chassis and lightweight doors and bonnet.
Its strengthened sub-frame, undertray, fully adjustable front and rear suspension, competition dynamo, and further tuned 1,366cc engine made it a formidable foe for those it came up against. The car was campaigned throughout the 1966 and '67 seasons by Broadspeed's own John Fitzpatrick, securing multiple class wins and podium finishes during that time.
Broadspeed itself would go on to develop the fantastic XJ12 which raced in the European Touring Car Championship in 1966 and '77, while the fate of the GTS remained unclear until its recent restoration and listing for sale. For £90,000 it's now up for grabs alongside an equally immaculate 2+2, giving one enthusiast the chance to own two irreplaceable chapters of Mini-lore.
