Caterham C400 - Petty Strut

[Ross_328i_sport]

Good morning,

I am presently rebuilding the C400 race over for the oncoming Mag 7 race series and was wondering if this petty strut offers any additional rigidity if the car has the full SLR roll cage? If this is the case then it is worth keeping otherwise it is an additional item that can be removed to reduce the weight.

Any help much appreciated.

Thanks
Ross

I have actually no actual knowledge - and while I can see that it might be beneficial if you had no full cage, with one, as you imply, I can't see it doing a lot. But since it's only attached by 2 bolts it's easy enough to remove and do a back to back test. Another advantage of removing it is that you can then get an instructor in the passenger side if you want to.

I'm guessing too but it looks like its there to support the roll over bar, not to provide any additional torsional stiffness. I'd also guess that the roll bar doesn't add much stiffness either; a full cage might though.

Thanks for the replies, unfortunately due to the compressor an accumulator there is no room for passenger so instruction is done via the Vbox with traces on the brake and throttle with video overlay. Will do some back to back tests on whether it makes any difference.

I think its just there to support the passenger side tonneau cover? Do you have one? I think i have one if you would like it? From a metric R300

It's a diagonal, so I would assume it will help.
