Ive driven one at Thruxton a few yeara ago the corner grip is amazing!! Im sure they do do road legal examples i can recall a EVO or CAR article testing one against a Westfield XR thingy.
Martinlaw on here used to race one, he said the gearboxes were the weak link
Exactly. You can't just pop down to Bentley and order a Speed8, but perhaps Radical (and whichever Manufactur they select to develop this with) might offer a road going watered down version of this peach, ala Porsche GT1.
