Not wishing to drift this great thread, but who makes roll bars for the 4/4 then?
I presume there may be different versions from FIA approved to 'street' use only?
Can you still have the roof up and over it?
I have always wondered about this as most Caterham's seem to have roll bars fitted... and there are of course obvious similarities between the cars...
Safety Devices, Techniques amongst others make ones that are certified. I do not believe the Librands one is. Depending on year / specific sub model 4/4 yes you can get the roof up. I have roll bars on both mine and I can get the roof up over the top...
