Speedway sells roll bars and different diameter
Bobcat Speedway sells straight bars at different widths, ratings, and sizes of the bars. They go by the 1/16 of an inch. You will need to modify the frame mounts and custom set of arms to hook to the lower control arms. They are adjustable with a spline ends. Hiem joints are used for the connection. I believe that Morris and Cobra 3170 are both running this setup. 18" wheels are on these cars with serious suspension changes. Rumor has it that they are running about 1,000 pound spring in the front and 1 1/16" roll bar. Don't remember the rear rates. Seams that 900+ to 1,100 pound springs are what the faster guys are running on road course and autocross. Car rides like a tank but handles like F1. Rick L.
