How the suspension works on the AX

The suspension system on the AX consists of McPherson Struts on the front and Torsion Beam axle at the rear.

Lowering Springs:

To lower the car using lowering springs, you will only need two springs. The rear beam can be adjusted by adjusting the torsion bar assembly.

Torsion bars:

Torsion bars use a twisting motion with steel bars to provide torsional rigidity in the axle assembly. This is how they work: - The torsion bars are situated in trailing arms and a tubular cross member. - When the wheel hits a bump, vertical motion is transferred to the trailing arms by a levering action, to the torsion bar. - The torsion bar then twists along its axis to provide the spring force.



It is generally considered lowering the ax 30-40mm is optimum for handling, the rear should be lowered by a similar amount but remain 10mm higher than the front.

Lowering can be done purely by fitting springs and lowering the rear but it is advised to fit uprated shorted shock absorbers for a better ride and handling. If a car is lowered with standard shocks they tend to wear a lot faster.

Suspension Details / Upgrades

The ax suspension is interchangeable with the following cars - Mk1 106, Mk2 106, Saxo (mk1 & 2). Whilst the 205 and 306 etc use a similar design they cannot be fitted to an ax easily.

3 Stud non GT/GTi

4 stud GTi Setup

Basic Description and how it works 4 stud GTi

4 stud Saxo inc Vts/Vtr & 106 inc GTi Setup




The standard GT wheels came in 3 stud and were. They produced both 13“ and 14”, both sizes were 165mm wide. They are very similar to the 4 stud citroen visa gti alloys.

Originally they had the 4 sunken sections painted black and a polished face, however its rare to find them in their orginal condition most have been repainted because they are very prone to corrosion.

For more information see the GT page


These were 13“ 165mm wide alloys produced only for the Gti, they are 4 stud and come in a silver painted finish (unlike the Gt alloys)

For more information see the Gti page


After market 3 stud Wheels

There isn't a large range of after market alloy wheels for the ax, people often swap to 4 stud to get a larger range of alloys. 15” alloys fit straight onto the AX GT with minor scrubbing depending on how low the car is, if your car scrubs on the o/s front its worth checking if your washer bottle is fitted correctly. With the non kitted cars (1.0 and 1.1's with the flat rear arches) 15“ alloys don't go on so easy, you need to either flair the rear arches or cut them and fit the GT kit. All 15” alloys should be fitted with 45 profile tyres to avoid scrubbing.

The most common are

  • Dare RLS and RLR which are a 5 spoke design they are 15“
  • Compomotive MO's came in two slightly different designs with the earlier having a flatter design on the spokes. They are 15” also these wheels are probably the best choice for those using ax's in motorsport
  • Ninjas are a more show car style alloy with 5 spokes, again these are 15“

Smartcar alloys are also 3 stud fitment however they do not have the same PCD so will not fit an ax, becareful that the alloys you buy are the correct fitment!

in most cases a driveshaft will fail on an ax, this is a common problem and is one of the main downfalls of owning a french car.

to start confirm which side it is and what suspension is on the car (eg, standard, vtr/s, post 99, non tapered or pre 99, tapered). now order the shaft.

to fit: first remove centre cap from wheel exposing the hub nut, crack hub nut 30mm socket, remembering that it will be very tight (200n/m) crack wheel bolts and lift car, remember safety first use axle stands!! next remove track rod nut and seperate track rod end from strut then remove anti roll bar nut (gti) or 2 13mm bolts (gt) or non if lower base model now remove ball joint pinch nut and bolt and crack ball joint from strut. put a clean bowl under driveshaft to diff join and pull the whole strut towards you it should pop out of gearbox end easy. remove cracked hub nut and pull out driveshaft from hub. fitting is a reversal of removal (as it says in haynes) it is also worth remembering that the oil seals have probably never been changed and therefore when disturbing then when taking out shaft they may leak. for the sake of a few quid change them!!
