[400TT]

Trev, my brother and I did many 1000k+ trips in our old Cobra with similiar style buckets to yours and after each leg we would get progressively more and more sore.

With the next Cobra we used MX5 seats, even with stiffer suspension, lower profile tyres etc, so much less compliance, on similiar trips we ended each day with no stiffness at all. Modern seats are so much more comfortable, not quite the same look though.

You might be able to improve your existing seats. What are you suffering from - back pain, numb bum, soar legs etc. You might be able to change the shape/postion of the seat to improve things.

Yeah, that grin will return each time you get into your Cobra.
