It can do, depending on the type, and how it is fitted.
The stock 'Z' bar fitted to later Beetles has free travel before the bar takes any weight. If there is no free travel, and the links between the
compensator [leaf spring or 'Z' bar] are solid, then any up/down travel will be transferred to the compensator.
If the torsion bars are re-set to lower the car, and the compensator is 'tensioned up' to raise the car to the required ride height, the compensator
will then be 'working'.
When the comp.spring is 'working', the roll-resistance will decrease.....and the outside rear wheel will tend to hold its [negative?] camber angle
better in a corner.
To avoid getting too complicated, I have avoided getting into the many other factors that can have an effect, such as the front suspension. Hope this
helps.
I'd rather wear a Beetle out by racing it than by polishing it!

If you imagine the rear of the car sitting on a very strong leaf comp.spring, and the torsion bars have been removed. There would be NO resistance to
body-roll, as the rear end would 'pivot' around the centre spring mount. Formula Vees run ZERO roll resistance on the swing-axle rear, often using a
coil instead of a leaf spring or 'Z' bar.
An anti-roll bar does exactly the opposite.....it resists body-roll, as its name suggests [without supporting any weight].

thanks, so in u post u have negative in brackets , n say it holds it camber better...... u mean it resists the negative? that is the leaf spring
effect is exerting pressure in an upward motion trying to make the tyre stay in a positive position

The swayaway camber compensator is a negitive spring also, it preloads the axels towards negitive camber, this also helps with a better ride, if you
want to get the car to handle better you can decamber it and run about 1 to 1.5 degrees of negitive camber, the swayaway style of camber compensator
does not increase the spring rate.

thanks for the info.... just so i understand ; positive camber when the wheels are tucked in at the top and angled out at the bottom, so the rear of
the
car is in effect lowered

Don't like to sound negative, but you've got that completely arse-about, Greg.

Pictures always help; I put a camber comp on my bug a couple of years back now and the difference it made was huge.

That's a lot better than trying to interpret 4000 words.
So the spring is still working.

greg do you use a camber compensator? if i remebor you do but it aint no normal bought one! when i had a swing axle dub i found that driving style was
more important than a shity camber compensator!

Yes, No, 8 Beetle has a comp, spring, which supports around 3/4 of the rear weight. The other 1/4 is via coil-overs.....torsion bars and spring plates
are no more.
The swing-axles are located by trailing arms, pivoting in line with the axle fulcrum, keeping bump steer to a minimum. A cable attached to the axles
maintains negative camber, but allows full travel on 'roll'. To complete the deal, there is an anti-roll bar.
A 'spool' in the diff. [thanks again, Henry] improves traction out of corners......but means a whole new driving style. 356 drums provide the
stopping power.
The front suspension is an early beam [adjustable, and caster wedges added], stock torsion bars, and Koni shocks. The link pins are now rod ends,which allows adjustment for camber [lots of negative]. The 'Mackie Strut' prevents the lower trailing arm from flexing inwards, helping to maintain
neg. camber. A 25mm anti-roll bar is fitted. Again, 356 drum brakes.
I have modified the steering to try to reduce bump-steer, and now have equal length tie rods.
Hopefully the 'new' 2276 motor [ex Ben Robinson] will make it even more fun to drive.........I'll find out in a couple of weeks time, at the
Nationals Supersprints.

"The 'Mackie Strut' prevents the lower trailing arm from flexing inwards, helping to maintain neg. camber."
Aaand, here was me thinking that the 'Mackie Strut' was a Scottish dance, performed when old guys got lucky.
Sanders diagram does simplify the understanding of operation of the Porsche COMPENSATOR Spring - but, I would argue that the springs sold through
after market
VeeDub retailers, while named 'COMPENSATOR' are in fact quite different in operation.
I recommend that anyone with the LinkPin/SwingArm affliction, keep a good eye on what is happening hereyou don't need to be a member to 'Search')
http://www.porsche356registry.org/356talk/1.html
These guys have been arguing about this stuff constantly for 40 years. For example, recently:
http://www.porsche356registry.org/356talk/search.html?keywords=compensator+ra...
I have found that opinions about SwingAxle set-ups are a bit like talking about religion...the only thing that each religion agrees on... is that all
of the others are wrong.

Exactly, if you take the question asked by grogy it will depend on what after market compensator you are talking about, i had one made down the gold
coast which was a empi rip off, made the car ride like a dray and preloaded the axels towards positive camber, the swayaway style improves the ride
and adds negitive camber. both of these are available over the counter to mere mortals who just want a bolt on device.

I'm keen to see the front link pin conversion to rod ends!
For what it's worth here's a shot of my comp spring that a clever person made for me; the only change I've made is adding threaded rod instead of
1/2 bolts so that I can add more pre-load onto the spring and let the back lean a bit more; working on the front....
and for proof that they can work exceptionally well; here is me at wakefield with stock beetle followed by stock beetle with rear height tweak and
comp spring; see the difference?
