2013 Porsche 911 3.4L Petrol · F1 WRF

Brake disc wear dominates the vehicle’s MOT record, with every test since 2022 flagging the front and rear discs as pitted or scored, and the latest 2026 pass confirming the same advisory on all four discs. This consistent pattern suggests the discs are approaching the end of their service life rather than an isolated anomaly. Tyre condition also recurs, with repeated advisories for cracking, perishing and edge‑wear on both front and rear tyres, and a single failure in 2025 when the rear tyre tread fell to the legal limit. The only non‑brake, non‑tyre issue was a corroded nearside front brake pipe noted in 2024, while a wheel distortion advisory appeared in 2025 and persisted as an advisory in 2024, indicating a lingering concern with the front wheel assembly. At 29,012 mi recorded for a 2013 model, the average annual mileage is roughly 2,200 mi, well below typical usage for a sports car of this age. Such low utilisation often points to infrequent driving or extended periods of storage, which can accelerate rubber hardening and corrosion of metal components despite the low wear figures. The MOT history shows no large mileage jumps between tests, so the vehicle has not experienced sudden high‑stress usage that would exacerbate wear beyond what the recorded advisories already reveal. Prospective buyers should scrutinise the braking system closely. Inspect the discs for surface scoring and measure disc thickness against the manufacturer’s minimum; any pulsation or vibration through the pedal at higher speeds can indicate disc thinning. Examine the brake pads for the thin‑pad advisory noted in 2019 and feel for any pedal sponginess that might betray uneven wear or a compromised brake pipe. The nearside front brake pipe corrosion warrants a visual check for rust, fluid leakage or dampness around the pipe and fittings, and a pressure test if possible, as a compromised pipe can lead to loss of braking pressure. Tyre and wheel assessment is equally critical. Examine all four tyres for sidewall cracks, perishing rubber, and tread depth close to the 1.6 mm legal limit; any bulges or uneven wear should prompt immediate replacement. The wheel distortion advisory suggests the nearside front rim may be out‑of‑round – spin the wheel on a stand and feel for wobble, and listen for a thumping noise at 80–100 km/h during a test drive. Verify that the central rear stop lamp now functions correctly, as a fault was recorded in 2019. Replacing the tyres and addressing the wheel distortion, together with a full brake service, will be essential steps before the car can be considered reliably roadworthy.
