DOLLY REAR SUSPENSION

[ALGIK]

Has anyone thought of doing a rear anti roll bar that is attached to the body ?

Like a tortion bar. Reckon it would make the back too stiif

Our race cars are fitted with body mounted rear sway bars. Each car is slightly different but have the same idea in mind.

A solid mount block it attached to the floor under the rear seat area, and the bar is attached via rose jointed drop links which have brackets on the rear axle housing. The bars are only relatively small at approx 15mm diameter and adjustable for fine tuning of handling. Currently the bar that is fitted to my car is not attached to the rear axle due to trying to get ride of an oversteer issue that the car was suffering from.

By having the bar body mounted some of the resistance to body roll is transmitted to the body rather that the opposite rear suspension arm.

The Mk 2 Marina had a rear ARB, which attached to the axle via the same clips as a Dolomite front attaches to the subframe.
This then came forward, and mounted to the chassis legs via Bushes.

My only problem with this was breaking the clips on the axle.

The bar was noticeably thinner than the Dolomite ARB, and was probably more effective at stopping the axle tramping, than as roll limiting.

Why on earth would you want a rear roll bar, is the handling too good????????

I don't get it...

its man stuff adam.



my original SE had a rear ARB fitted, not to the chassis tho. took it off and the handling certainly seemed better to me, more predictable.

I'm tempted to lose the one off my sprint when its done, but thats probably still some months away!

Right mines coming off tommorow, Have to go underneath to see what that noise is

Jesus the handling is much better with it off. I think what is happening is when you corner at speed the back is starting to let go, so you get the feeling of it pointing in to the corner more. Where as with the ARB it understeers first then snaps to over steer, its progressive oversteer now

Out of interest, I have two very different arbs - one that is dead straight between the trailing arms, and made of something very hefty (came off a 1500), and one that has a dipped down middle section (advertised for rwd vehicles).

Is this difference just the fwd and rwd thing, or was there something else to it?
