Roll over hoop
Discussion
Whilst I am in the mood for posting does anybody have one of these fitted? I am looking into stiffening up my chassis and this should in theory be helpfull. Can anybody tell me who makes these and roughly what the costs are?
Other possiblities are fitting additional bracing (would love to know how the V8 chassis differs) or indeed fitting a V8 chassis (can't afford it and not sure if it would fit anyway?) Finally I am considering pannelling the underside of the chassis with alluminium as this would also afford much needed protection. Using rivnuts would make the pannels easily removable.
Any thoughts?

Tower View Race Services in London make these. Their website has all the info you need.

Mine was the first Tower View / Roll Center bar, and a lot of work went into getting the design right. It is all too easy to fit a bar which obstructs the rear view, prevents you using the original seat belt, restricts the seat adjustment, doesnt line up the rear straps and so on.
People say the bar stiffens the chassis up. Personally, I can't say I noticed any difference and from the design I wouldn't expect it to make any significant difference. It is just a bent tube connecting together four points which were already rigidly connected to each other. What it can do though is stop the body moving relative to the chassis which might help if your body mounts were knackered. It will also transmit more suspension noise into the cabin which can give the impression of a harsher ride.
Improving the chassis stiffness is a worth while aim. I'm not sure how practical it would be to panel in the whole spine and there may be cooling issues if you did this, but I'd be interested to know if you find any improvement. For what its worth, my V8S is probably one of the more powerful cars you'll find on that chassis and torsional stiffness has not been a problem to date. Areas that I think are worth paying particular attenion to are the trailing arms (especially if you stiffen up the suspension), front wishbones (tend to bend under repeated damper loads) and the rear turrets (could really do with more support at the top, I think this would improve the wheel hop problems that dog these trailing arm systems.

I have a Roll Centre Roll bar fitted and have been told by Mrsheen that my car feels more solid than his, so it possibly does. I must have a later roll bar as I use normal seatbelts, couldnt be doing with a harness, it was the first thing I got rid of, its too restrictive when driving on the roads.

Thanks for the info chaps. I have a lot of changes planned but will keep the car virtually standard for the comming summer until the plans are finalised. The purists will probably hate me but I bought the car for the following reasons:
Cheap initial outlay
Cheap Ford mechanicals
Seperate tubular chassis
Rear and pretty

V8 S's can use the standard seatbelts, V6 S's can't

I had a Tower View roll bar fitted to my V8S. Only downeside was that the seat didn't recline quite as far.
The bar comes complete with new upper seatbelt mounts that improve the comfort of the belt. V6 version is exactly the same.
Got to agree with this, if you are over 6' I really wouldnt reccommend a roll bar, unless you need one, as it does lose you about 4 inches of travel. I find it OK, at just under 6' but mine is as far back as it possibly can go and its just about right! God knows how GreenV8S manages
Yes I wondered why the V6 ones couldnt use normal seatbelts as mine are bolted to a mount on the bar itself!

In the V6 the bar mounts to the chassis where the inertia real goes. Although the disadvantage is I loose the seatbeat, the advantage is the seat does go all the way back. I think I've got the better deal.

Mine (V8S) is the same, except that on mine the inertia reel stuff has been reattached onto the front of the bar.
