Hi Steve,

Sorry no spare as have new set waiting for me to have time to put on, but I'm pretty sure you have to replace springs in pairs

Hi

As John said,,get in touch with Paul Anderson...I have an 86 S2 as well and I needed the bottom bush (MOT fail) last year and he had lots....

As yours like mine has adjustable seats, you can normally get away with an old spring as long as it sits evenly...if not you can adjust one side or the other...until it does...

All the best Brett

You need to replace springs in pairs. If you value your life, and want your car to handle predictably in an emergency, or at speed or during heavy braking, do not just replace one.

You can differentiate between the different springs as they have different colour paint markings, and also different numbers of dabs of that colour paint to sort them into tolerance groups. The different spring groups were for adjustable/non adjustable perches, and different types of shockers fitted in different cars. Refer to WSM 40 - 42 through to 40 - 49 for a rundown.

If you have a cracked/fatigued spring on one side you should be carefully checking all suspension components on that side and the other side as well. Why did the original spring crack? ... maybe a hit, or hammered on rough roads?

If you replaced one spring you could end up with a 'pair' of springs with rates at each end of the spectrum of factory rates and tolerance groups. A matched pair from a later model car would be the better way to go as they will have less chance of being fatigued or saggy.
