Rollcage for roadgoing Cerbera ?

[GT6k]

I am looking to put a rear cage/rollover protection structure into my Cerb for sprinting. I can see various full race ones but I am looking at any ideas for a bolt-in one that doesn't need major surgery.

I thought there was built in protection in the roof structure. Is that not good enough?

I like your picture at the pod. What was your time?

Unfortunately I have to put something in to meet competition regs so the built in hoop doesn't count.

The event at pod was a drift day not drag, great fun if you have a set of tyres to say goodbye to.

Say its not so...…..

In the French TVR Car Club, we have a member who has modified his Cerbera to participate to official championships.
He had to remove the original roll cage to fit a certified one instead (plus the fire extinguisher, certified bucket seats, battery cut off...).
If you want more information I guess he will be happy to share about this project even if you don't speak french :-).

Thanks that's interesting and the videos are entertaining. I am not willing to rip the interior out of mine as i want to keep it comfortable for road use.

Thanks for the original post and the replies... I am in the same situation. Having looked at options I have no desire to ruin the interior of an early and original Cerb to try and get a roll bar in, so looks like its a no go.

ian try andy at APM, when he looked after my cerb he had a couple of race cars with cages that he got fitted so i am sure someone smart could work out a half cage. i suspect the challenge will be stripping out the trim, removing the existing roll hoop etc and reproviding a new half cage, then a retrim over those areas affected because the new tube will be bigger.

Jes, yes that would be possible but almost certainly too expensive and too complicated. I suspect my financial manager will point out that I could buy a perfectly serviceable MX5 for under £5k and be on track next week.

Indeed! Or perhaps a series 1 Porsche Boxster (although I dont know if I could live with myself)?

A chim or griff would be easier to fit the roll cage?

Ian you are not wrong, probably get a prepared one for a bit less than that. One small problem though will be frustration at how long it takes to get form one corner to another as i found out with my daughters MX5 - compared to a cerb they don't really accelerate - not at at all - i mean not even down a hill - even a steep one - with a strong following wind

Very sorry to hear about the road going class change, Motorsport UK can’t be lobbied for a reversal to previous category? So now you can’t sprint or hillclimb a Cerbera without ROPS?

Ian, I know of a sorted Turbo MX5 Mk1 that’ll be on your budget-

Oh Jes, my MX5 that apparently doesn’t accelerate beat your Griff at Abingdon last year.... See you at Gurston!

That looks like a great car Howard.

Your mx5 is rather special! Sadly can't make Hurston 😟😟😟
