TVR Roll Hoop / Cage
Discussion
Took mine off Steve but sold it on I'm afraid - not so helpful! It was a RollCentre product and the rear deck behind the seats was cut away and the rear stay bars just bolted onto the chassis tubes. The floor was then re-bonded to the roll hoop. Pretty weak to be honest, don't think it would have survived much of an impact, more for cosmetic effect really. The front fixings were onto the original seat belt mountings, so much more secure there..
Steve, the one in my previous S was custom made by Guglielmi Motorsport. The car used to be owned by a guy who worked there and he rebuilt the car for sprinting. It was made from bigger diameter tubes than the Rollcentre one and had some additional cross bracing. There was even an FIA stamp of approval on it.

The above was probably a bit over the top (no pun intended!), the Rollcentre one in my current S (fitted by Liam when it was his) is more than good enough. Actually it might be worth checking with Liam because when we were looking at a potential project he found a roll bar manufacturer near him who also did them for the S Series.

I managed to pick up a second hand Safety Devices Roll bar for my S2.
The main hoop mounts to the seatbelt mounting points and through the floor using the body mounting bolt just below.
The rear stays bolt through the rear parcel shelf and I welded some plates to the chassis while I had the body off but you could probably fabricate some plates that would just bolt on.
