Left and Right Are Genuinely Separate Parts — Confirmed by Toyota's Own Catalogue

Genuinely worth knowing: Toyota's own parts catalogue lists rear coil springs as lower-left and lower-right references — distinct, non-interchangeable parts rather than a single spring fitted to either side.

Toyota GT86 Rear Springs: A Part That Fails Quietly, Then Suddenly

A rear spring often sags gradually for months without an obvious symptom beyond a slightly lower ride height, then fails suddenly at the coil's end with an audible clunk — worth bearing in mind if you notice one rear corner sitting lower than the other. Toyota's own guidance notes that coil springs aren't especially prone to failure under normal use, but cutting, clamping, or heating a spring genuinely compromises it and can lead to premature failure.

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

Toyota GT86 Rear Springs reference plate

OEM Part Number: confirm via VIN — rear coil springs (aftermarket) Kilen 64109 / KYB K-Flex RA5886

Accuracy note: Covers the Toyota GT86 (2012-) 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 listed by Toyota as lower-left and lower-right references specifically — not a generic "rear spring" part covering both sides.

Rear coil springs (aftermarket)	Kilen 64109; KYB K-Flex RA5886 (270 mm); Lesjöfors 4292650
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
Standard trims, lower right	Genuinely a different part number from the lower-left spring — confirm side before ordering
Standard trims, lower left	A genuinely different reference from the lower-right spring above
Sport-trim spring, where fitted	A genuinely different, stiffer spring from standard trims

It's worth doing the Toyota GT86's rear springs as a pair rather than one at a time — mixing a new spring with an old, sagged one on the opposite side throws off ride height evenly and skews handling.

Toyota GT86 Rear Springs: What It Does

On the Toyota GT86, weight support at the rear and absorbing a bump's first impact both fall to the coil spring, working in tandem with the shock absorber rather than substituting for it. A broken or sagged spring drops ride height, can affect headlight alignment, and in bad cases is enough to fail an MOT.
