Ride height

To correctly measure ride height: Measure heights $$H1$$ (front) and $$H4$$ (rear) from the centre of the wheels to the ground.
 * Fill the fuel tank
 * Correctly inflate the tyres
 * Unload the car
 * Park on a flat surface
 * If the torsion bars have recently been adjusted, drive for a few miles to settle them.

Measure $$H2$$ (front) and $$H5$$ (rear) from the underside of the chassis arms to the ground.

Calculate the ride heights as shown:


 * Front ride height $$HF=H1-H2$$
 * Rear ride height $$HR=H5-H4$$

Normal ride heights
Note for cars with "tripod" inner driveshaft joints (that is, the majority of post-1970 R4s), Renault specified that front ride height is 5mm lower (i.e. $$HF=46mm$$).

The maximum difference in height between left and right is 10mm, but the driver's side should always be higher than the passenger side.

For ride height adjustment, see the page on torsion bars.
