We were asked about building a roll cage for a car headed to Bonneville. Not necessarily a straight forward task in an ordinary steel bodied car, even less so in a fibreglass Jensen CV8. The car uses a central ladder frame chassis with no support out at the sills. We had to build a subframe and weld it to the cars chassis which could support the roll over structure. The car just ran successfully at Pendine last week and is due to go out to Bonneville later in the year.
