I have used both Kirkey seats, the Road Race and Intermediate. The intermediate gave better feel of the car but was a huge pain to get in and out off. Having a removable stering wheel may have helped, but I did not. If you have a big sedan-type car this may not be as big a deal. Also for me the big rib supports of the intermediate in in the way of my arm for shifting in my car.

Best advice is sit in a few seats in cars, not at a supplier's showroom!
