F87 M2 Rear Spring Options

[Megaflow]

Morning all.

My F87 M2 has just been in for it's air bag recall and they have told me it needs a new rear spring, normally I'd replace just the broken one, but on a car like this I feel like it is worth replacing both.

So far the only options seem to be a really clean used set for £100 or a pair of genuine ones at £310.

Unless anyone knows of something else I have missed, I have check all the usual online sources, ECP, Carparts4less, Autodoc, etc

TIA.

Unless you go for a full set of aftermarket ones oe is probably best.
I personally wouldn't buy used springs.
No experience of the M2 sorry but as a general rule of thumb the above is what I would do.

It looks like new OE is the only option. Loads of lowering spring options, which it absolutely does not need without much better dampers.

Seemingly no pattern options available, so OE it must be.

As much as I like the idea of the £200 saving of the used ones, they fail so often, that is too much risk.
