sforshaw #3 - 'It's rarely quite so simple'-  yes indeed it is quite that simple having seen the test results from the tests that the club commissioned.

The latest double diagonal bar resists collapse from side ways forces more ably than the single diagonal bar.

#3 Rarely that simple. I agree. When I was discussing buying a car from CC they had a different view on roll bars - even a 620R comes with standard roll bar unless a cross braced one is ordered as an extra.

The OP may also need to budget for a new boot cover, and a different half hood if used.

Well, not quite so, and I wouldn't want the Club's work in this area to be misrepresented.

For anyone with an imperial chassis car wondering whether to buy either a single or double diagonally braced trackday bar, rest assured that the work carried out by the Club showed remarkably little difference in performance between the earlier (single brace) and later (double brace) bars.  Actually, having just checked, I'd say to the point of any difference being negligible.

To recap the summary of the Club's investigation - when assessed using an internationally recognised test standard, both examples of trackday bars (single and double braced) performed substantially better than either of the earlier or more recent standard, unbraced bar types that were also considered.

Best option is an SLR cage though with lowered floors Thumb Up  even though these cages are like hens teeth
