Hi Beltempo,
Next winter I'm about to let install this rollbar made by Librands. I would add 100 GBP to get it black powderd (info by phone call with the manufacturer). The benefit is that it comes in two sections. The lower part will be fixed mounted into the car and will stay anyway. The upper part offers three choices, install the road going bar which fits under every kind of hood, old style or easy up, or 2. leave the upper part away for nicer looks or 3., you can mount a taller racing rollbar upper part, fixed at the same base, this one is higher than the weather so you are safe on the track but w/o the hood.
