Rolling Rolling Rolling...
New style roll hoops from Peninsula Automotive.
Discussion
Makes it look like a Merc SLK or TT cabrio - Griff drivers don''t run hair dressing joints !? ;-) Of course the only serious solution to this roll over worry is - buy a road Tuscan where its built in, or better still compromise the fresh air for a really safe drivers car - buy a Cerbera!
Surely the purpose of 'hoop' style roll bars is to provide some roll-over protection whilst not compromising the 'open' feel of the car as much....a single bar across the back makes the car feel more enclosed. (IMHO). Certainly does on the road Tuscan as compared to my Chim (IMHO).
Tuscan owners care to comment?
Very few cars manage to make roll-over hoops look attractive....IMHO.
quote:It has to be sold as a cosmetic item because it hasn't been tested (I don't think Peninsula are about to go roll their Griff to prove it!). It is mounted onto the chassis and is of decent material so there's little doubt it would prove a lot better than no protection at all.
Any idea whether this is sold as a safety accessory or just a hair-dresser add-on?
Those rear hoops don't seem to have any rear stays - looks to me like they would fold flat if the car landed on them. The MSA have fairly comprehensive rules that competition spec roll bars have to comply with. Those rear hoops don't look like they comply with any of them and I guess they are mainly for looks. If you want real roll over protection I think it's worth looking at the Rollcenter/Tower View bar, which is used by various sprint competitors.

Are you all completely mad?!! It sounds like you are all expecting to roll your cars at any moment - am I some sort of pansy, 'cos I've never felt like I was going to roll my car. Is sensible driving not an option here?

Actually, dahlings, I reckon a nod to the market place won't do TVR any harm - might make them more popular with the mainstream - maybe then us long-suffering TVR-ites might get some build quality!!

Edited by nubbin on Tuesday 10th July 10:29 quote:This can work, but I've also seen this done badly with the brace attached to the middle of the bar where it is relatively ineffective. It has got to be attached close to the uprights, otherwise it can't stop the bar twisting/folding. Better than nothing I suppose but it's so easy to make a really strong roll over bar so I don't understand why you would knowingly fit a weak one. The MSA tell you how they should be designed, it really isn't that hard to get it right if you stick with the conventional goal post with two rear stays. IMO a roll over bar is crucial safety equipment not a fashion statement. (If you feel differently feel free to disregard the above!) Cheers, Peter Humphries (and a green V8S)
While I was having the car serviced last time I did see a goal post type bar with a detachable diagonal bar coming forward into a rose jointed bolt in the passenger footwell that they had fitted.
Ive seen 2 Griffs this month which were both stuffed at the back end, one of which suffered an impact backwards directly on the o/s/r wheel, when I saw the car the driver had been cut free..alive.(serious head/spinal)... the wheel had come through the shell pushing the corner chassis member into the car behind the driver, the wheel pushed the drivers seat a foot and a half into the dash....complete with wishbones...
if your going to do the crash thing make sure its not backwards!!!!
