Hi coach, nope i don't get a numb bum in the T350! You can get thicker cushions from TVR though. Don't get a numb bum on the way to the yellow meet will ya Dave
The earlier cars seem to have much thinner pads (or a different design?... i.e. even before the change to Tuscan type seats). Never had a numb bum on the later seats, and, incidentally, I too like going sans-pad
You can get thinner pads made up too - I have one (6ft 5). Holds you in better, but doesn't mean the backs of your thighs lose blood supply after 100 miles driving like they do without any pad in (I go padless for trackdays though).
