Mini Cooper Rear Springs: Specs, Fitment & Common Faults

Genuinely worth confirming first: drivetrain and left/right side both affect which rear spring fits.

A Part That Fails Quietly, Then Suddenly

On the Mini Cooper, the typical failure pattern here is gradual sag over months, barely noticeable beyond a marginally lower stance, followed by a sudden break at the coil's end with an audible clunk. If one rear corner appears to be sitting lower than the other, that's worth investigating.

Before you buy: drivetrain, trim, and left/right side all affect spring rate and fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — rear coil springs (aftermarket) Monroe SP5113 / Sachs 992377

Accuracy note: Covers the Mini Cooper (F56 2014-) as listed in the UK aftermarket catalogues. Rear coil springs are sold as a pair for the axle and should be replaced as a pair, because a new spring beside a tired one leaves the car sitting unevenly. The right spring depends on the engine and gearbox, the suspension type (standard, sport or heavy-duty) and, on some cars, the body style. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so match a genuine spring against your VIN if you want a guaranteed fit. genuinely worth knowing: rear springs are sold in left/right pairs matched to a specific rate marking — confirm the marking on your existing spring rather than assuming from trim alone.

Rear coil springs (aftermarket)	Monroe SP5113 (245 mm); Sachs 992377 (standard); Bilstein 36-343393 (standard); Suplex 06595 (standard, 240 mm)
Genuine (OE) numbers quoted	None quoted in the catalogue listings — the genuine spring varies by engine, suspension type and body style, so order it against your VIN
Front-wheel drive, standard rate	Genuinely a different spring from the AWD version below — confirm drivetrain and side before ordering
AWD	A genuinely different spring from the front-wheel-drive version, reflecting the different rear axle layout

Fitting the Mini Cooper's rear springs one at a time tends to backfire: pairing a fresh spring with a sagged original on the other side leaves the car sitting unevenly and biases handling to one side.

Mini Cooper Rear Springs: What It Does

The Mini Cooper's rear coil spring carries the weight of the car's back end and takes the first hit from any bump, working alongside — not instead of — the shock absorber. Once it sags or breaks, expect a lower ride height, possible headlight aim issues, and in severe cases, an MOT failure.
