I'm looking for something to restrain me in my Dolomite's seats a little firmer as I'm bored of bracing myself against the door or transmission tunnel. What kind of options are there for harnesses to hold me down a bit better, or is that not possible with standard seats. If not, then no problem I'll carry on bracing as I don't want to lose them as they're rather nice.  Cheers! |

you should be able to fit harnesses with the original seats in your dolly.
the tweeks catalogue, although full of tat, do sell some useful stuff.think they start at around £40.
if you can, try and mount the rears to the parcel shelf or there abouts.not down behind the seat, theres a reason for this, but at this moment i cant think what.
i plan on ditching the nasty 60s static belts in favour of some harnesses when funds allow.

That reason being that in a crash, if the belts are secured to the floor, the seat will just fold up taking your spine with it and smashing your head into the steering wheel.
Standard seats with harnesses are the ultimate in cool IMO. Really you should have head restraints but i think they look cooler without.

IF the rear straps aren't parallel to the floor, you'll get pulled down into the seat in an accident and your spine may shatter  They should go straight back behind you, but get the parcel shelf strengthened with a bar or plates or whatever. Parcel shelf metal is fairly thin and you don't want the rear harness mount just pulling the shelf out if you hit something... Also, five point harnesses are a MUCH better idea than four point - you can't slip underneath and "submarine" into the dashboard/steering column, but they may not work with your current seats... |

We Did some Calcs when Fitting Harnesses to a Pulsar GTIR as the previous owner had wrapped them round a Rear Strut brace  Looked OK, but we worked out that an Impact at 30mph with 1 person on board would pull out the strut brace completely We ended up with a 2" Scaffold tube with 1/4" Plates on either end, bolted through the strut towers with 4 bolts and plates behind. Do Not think that a a rear shelf will take the single shear loads that a Harness will introduce in a crash  Use the rear belt mountings if you have to. I personally would not use 4 point harnesses in a car without a Cage. In a roll, with conventional belts you have a chance to lay over when the roof comes in.... If you are harnessed in, that only happens when the roof collapses the seat back Seen it happen.... not pretty I walked away from a Multiple end over end roll in an early Renault 5 TS at 55-60mph no cage and 3 point lap belts A Freind of mine is in a wheelchair after barrel rolling a Manta with Harnesses but no Cage Normal seats are not designed to work with Harnesses either, Race/rally seats are. Just my experience, but I`d hate to see someone end up the same way HTH Dom |

Mine's really not for track work, it's just even under gentle cornering I seem to end up going out the window. Unfortuatnely mine would have to be bolted to the floor in all instances.
I think I'll mull over it for a bit, and go for a 5 point with standard mountings as well as retaining the 3 pointer for less vigorous driving. Quiller sell some nice branded Triumph ones if my memory serves me correctly.

I've not read this thread, I'm sure there have been some top answers but heres my waffle... For a better and safer driving experience I'd suggest binning the Dolly drivers seat even though you like it, a more suitable example with supportive bolsters will stop you from sliding around without the need for a harness. An entry level Momo, Cobra etc are around £90. Or even a Recaro out of an RST, but that would be grey...would match your floor mat though I'm not sure how much you use your motor but unless you opt for a retractable (Securon?) harness a fixed pair will be a curse word for road use, how many times do you lean forward to check for oncoming traffic whilst pulling out of a junction or to bend down into the passenger footwell to pick something up for example? Rear passengers would be a no no too, unless you retained the factory belt and unclipped the 4-pointer from the eye bolts each time someone got in the back. But on top of all this, in the event of a roll you won't be able to bend down to save your neck, you will be fixed upright, so if you really want harnesses go for a full FIA app. bolt/weld in cage, not a road use scaffold job that certain specialists flogg. Also if you do fit harnesses then remember to put 'sandwich' plates behind the panel you are screwing the eye bolt into, this simply spreads the load in the event of an accident, preventing the bolt from pulling clean out. I tell you what would be good though...A set of brand new Spax adjustable shocks or a spanking new Rimmers half engine for a dolly sprint? ;D I've got various other bits for sale too, e-mail me on taity_boy@hotmail.com if you're interested! |

....whilst we seem to be on this subject... whats your general thought on rollcages in road cars..and pro's cons of weld in and bolt in cages? Cages in Road Cars can be a PITA, depends what your doing with it ? If the car is any more than just road legal for event purposes IE you actually use it on a regular Basis, then get a Bolt in Cage with removable diagonals and door bars. You can also remove the cage later if the car gets damaged and swap it into a new one. Buy a decent one from Safety devices, Sparco, Rollcentre etc But they do make the car Heavier, less practical day to day and harder/more expensive to insure HTH Dom |

my 2p worth:
i had 3 point harnesses in one of my old minis, don't think i'd ever have them in a road car again - they're just not practical
IMO you really cannot beat decent seats tho

i have bucket seat, but I'm holding off on harness until i can secure a cage for my car... gotta do things properly Having just sorted out a cage for the ZS, what's the deal on harnesses in competition cars then? The ZS will have a full cage, motorsport seats and no interior so where should the harness mounts go. Most rally cars seem to have them attached to brackets on the floor, which was pretty much what I was planning. Advice? |

ive travelled from coventry to snetterton in passenger seat of a caged and harnessed car with no interior. i loved it cages and harnesses in road car just make normal slow driving so much more fun....only thing is as a passenger having harness can be slightly fristrating if you want to move around a bit more. |

I have mine bolted throught the base of the rear bulkhead. The harness goes through the centre of the rear seat cushions like this...  with a speader plate in the boot, I think this is the way to do it on a Mini. Am after a matching harness for the passenger side as the cage legs sit where the reels sat.  How about a set of GT6 or Stag seats, I don`t know what they are like, I guess they have more lateral support though  |
