Lol on your response Charlie, one thing you will notice on this forum some sections are not read that frequently. But hi there.
I have a Tigercat they are a little snug. I'm 6ft 1 size 10 shoes and manage reasonably well. The Dax Rush has recently been bought by MAN Motorsport. I looked at their reworked Rush, BMW powered, at Stoneleigh and it has a little more room, might worth a visit. Are you planning a build or secondhand? http://www.manmotorsport-rush.co.uk/
