Would like to take my car to the track 3-4 times during the summer. With a helmet on, the headroom is non-existent for someone six foot tall. It takes some of the fun out of it when you can't get comfortable. I see at Dali Racing they have replacement seat cushions that will lower the driver's position by 2 inches. Has anyone tried them and when your not at the track does the seating position still seem OK? Thanks for your help in advance.
