I have been tracking my 2017 Mustang GT for two years but am still most comfortable running with the beginners groups. My problem is that my hands are old and they get cramps from too tightly gripping the steering wheel, especially around turns like 2 at Thunderhill, or 6 at Sonoma. I think being tightly strapped-in would let me relax my grip but I would like to avoid a roll bar and six-point harness. My idea is to get a good racing bucket seat and swap it for my stock seat for track days. My questions are: How likely is just the seat, with only the stock belt, to give me the the lateral support I need? And which seat would be best? I am tall and narrow. Thanks for slogging through this odd post.
