roll bars- i am tracking and sprinting and cant see how it would be very good without roll bars for what i do, the handling is great, despite it being set up by 2 of us in my garage with a laser floor leveller and string etc ! lol
i'd go for it and fit them , you can always set them to the softest position or disconnect them to try it without, but if you dont fit them its a fair bit of work to fit them afterward.
andy has a new clip of his car going round track which might show you how good the roll bars are,
