Pug106 Suspension Tuning (At the Back)

The rear of the 106 uses torsion bar suspension instead of springs, which means lowering it is not as simple, although no replacement parts are required.

Torsion Bars

It is fine to lower the back of the car by just adjusting the torsion bars to make the rear ride height match the front, but if you have lowered the front and used harder spring and damping rates, the torsion bars at the back will seem soft and bouncy in comparision.

This can be solved by using thicker uprated bars which will be stiffer than the standard bars.

However, uprated bars are a pricey modification, usually around £300, but if your after the best possible handling, then they should be on your list.

If the car is to be used for competition purposes then these become essential, as the standard bars wont stop the wheels hitting the arches over serious bumps, causing big damage.

Anti Roll Bars

An anti-roll bar, as you'd expect from its name, prevents the car from rolling about too much on its suspension when cornering hard.

It works by controlling the amount the car can roll, by transferring some of the weight on the outside wheel when cornering, back on to the inside wheel, to try to keep the car as equally balanced as possible and produce a more stable grip on the road as a result.

The anti-roll bars that come on the cars as standard allow too much body roll, which results in the front wheels lifting off the ground under hard cornering, therefore losing grip.
