Rear Anti-Roll Bars


Hurricane 1600

Recommended Posts

Well here's a thing, I agree with Dave!

I put one into the Silverback - see below - but when I got around to adjusting it, whatever I did nothing happened.  Eventually threw it out.  After all, a swing spring is supposed to do an equivalent job.

an anti roll bar can work on a fixed rear setup as it helps transfer energy on cornering to the opposite side, a swing swing works by letting the body roll as opposed to lifting up the wheel not under load on cornering, soo, its pretty stupid to put one on a swinger as the roll energy is taken up in the swing spring setup, but on a fixed spring it can help under hard cornering as you dont get the body roll taking up the cornering energy,,  i thinkk...  :-) :-D

it sounds like they are a waste of time on the triumphs, I broke the one on the back of our nissan (dont ask ... roundabouts are fun) and i takes driving the thing scary to say the least - sideways in a fwd car with the real tyre rubbing on the arch, I think my dad managed to break it once before as well!

I changed my rear link mounting point, as suggested by Dave.

Rear end went from this

to this

Very happy with how she handles. The front end was also lowered.

on hard braking the weight transfers to the front and the rear body lifts giving positive camber and reduced traction.more than once the rear of my mk1 gt6 beat me thru the turn. i have a rear bar(addco-usa) with arms that clamp to the inside of the upright lower bolt. it makes the rear a little stiff over low speed bumps but deaccellerating through fast turns it is more predictable. i am more likely to disengaude the clutch than hit the brakes or lift the throttle for fear of weigh transfer and loss of rear grip.

camber compensators work on swingAXLE rears by working in the opposite manner of an arb, with a CC, as the outside wheel goes up ie rear suspension compresses, the opposite wheel is forced down to try to keep in contact with the road.

I have tried arb and cc on a mk1 gt6, the arb did nothing, the cc did help a little.

there are a couple of dozen of my previous creations out there in triumphland, but I won't be making any more

I always found it was pretty hopeless increasing rear roll resistance because the torsional rigidity of the chassis (especially on 6 cylinder cars) was so poor.

Even increasing spring rate meant the chassis - bulkhead area moved more than the suspension (and that was an a totally non standard chassis with reinforcements everywhere).

Far more can be done to those cars by improving rigidity than anything else, and I'm still convinced the chassis gets tired and softened out......try driving a really new or low mileage one, you'll see what I mean!

Quoted from secretsenor Thanks Andre - Now I get it! ;D


Nice easy mod to do, and made a huge impact on the car's handling.
I did not go down 2" I only went 1.25" basically the space of the washer.

If you do it, you will need some extra brake line, I bent some of my old hardware and attached my flex lines to those.

I do run a CC bar. Not sure how she's feel without one, have no plans to find out :)

Josh,

I meant that I do have never been able to really tell what the wheels are doing on my GT6. I can feel the weight transfer as the rear goes light and I have always attempted to drive the car smoothly and be progressive with my inputs.
However I am only too aware that I do not have sufficient talent to really drive a GT6 fast. Also I have been corrupted by driving moderns which are so more forgiving of bad driving.
The Focus I now have is the first modern I have driven that one has to really think about when pushing on.

Also of course my reaction speed is slowing down as I get older- get by on experience nowadays.

I had my driving standards destroyed by 12 months of various gutless Focus's and Mondeos' where you have to lift off mid-corner to make the nose tuck in in an attempt to negate the built in understeering tendancies and avoid the fast approaching hedges.

As you can imagine that results in a bit of fun when I get back into a RWD Triumph!

Certainly enough to scare my passengers... :-)

I too now have a higher powered FWD car, with much less designed in understeer, and buckets of Torque Steer.

I suspect that a few days away from the Astra will be needed before any future RBRR or 10CR etc.

Cheers

Colin

I did notice that your camber was 'moderate' - but not to be confused with easy listening.

I will probably go 1.5 - 1.75 inches.
I have finally extracted a cheque out of my insurer for my accident and will be getting some wheels. Thinking about 15's but am still concerned about offset - My old wheels have 'dissapeared' and I am having difficulty finding out what the original offset was  >:( (thinking about 26p on either 14x6 or 15x6 wheels)

How do you find your inline breaking with the greater rear camber?

What is a CC bar?

I was worried about going too far specially with the 15" wheels.
Not to mention brake line issues and what not. I want the performance, but don't want the car to be too crazy. I could drill more holes if I want to go lower. :)

Braking she is fine.

The camber compensator bar.

Its a bar which limits the tuck factor.
