OEM Part Number: confirm via VIN — front struts (aftermarket) KYB 3348085 / Bilstein 35-228370

Accuracy note: Covers the Toyota GT86 (2012-) as listed in the UK aftermarket catalogues. Front struts, lower arms and top mounts are sold by side and by suspension spec — standard, sport / lowered (S line, M Sport, R-Line, ST-Line etc.), heavy-duty and adaptive / electronic damping all use different part numbers, and some makers split by engine or front axle load. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Confirm the fit against your VIN, and replace struts and top mounts in pairs.

A Genuinely Money-Saving Fix Worth Trying First — Toyota GT86 Front Suspension

If you're hearing a muted "thump" or "pop" from the front suspension, particularly on rebound over speed humps, this is genuinely worth trying: one documented case saw exactly this noise resolved completely simply by lubricating the lower control arm bushes, which had dried out, rather than replacing any actual component — using a silicone-specific spray on the bushes.

A genuinely honest, real account worth knowing: one documented case saw drop links and anti-roll bar bushes replaced with zero improvement to a persistent clunk, only for the actual cause to turn out to be recently fitted brake pads rattling very slightly within the caliper — not a suspension fault at all.

It's also worth knowing that a clunk specifically over wide speed humps, but with no unusual noise on smaller bumps, has been documented on brand-new cars and can sometimes trace back to a subframe bolt not properly torqued at the factory.

Toyota GT86 Front Suspension Strut: The System That Quietly Does All the Work

Everything the road throws at the Toyota GT86 — bumps, potholes, cornering loads — passes through these components before it reaches the cabin, so wear here tends to show up as vague symptoms rather than one clear failure point. A systematic check beats guesswork every time.

Before you buy: suspension components vary by trim, engine weight and whether your car has the standard or sport-tuned setup. Always confirm against your VIN before ordering.

Toyota GT86 Front Suspension Strut: What It Does

On the Toyota GT86, the front suspension strut combines a shock absorber and the coil spring's mounting point into a single assembly, controlling how the suspension compresses and rebounds. Once it wears, the car keeps bouncing after a bump instead of settling quickly, and tyre wear often becomes uneven if it's left unresolved.
