I was at Williams a week ago and was shown their race prepped Plus Four. It had a full race spec roll cage. Not suitable for a road car where the hood needs raising. I was told a fast car with no major upgrades....yet!
They had fitted a Librands roll bar to my previous trad car with no roof problems for a nine stud version not easy-up.They also modified my tonneau cover to fit round it at the same time.
I'd be interested in a roll bar for the Plus Four.
