SevenSense

SevenSense is the fast way to find the right torque figure for your Caterham Seven — without digging through a build manual with oily hands. Set your car once — model, engine and chassis spec — then ask Colin, your Caterham companion, for any fastener. Type it or say it, and the figure comes straight back in Nm and lb·ft, with the bolt size and the source manual shown every time, so you can check it against the fastener in your hand before you reach for the torque wrench. WHAT YOU GET - Ask by voice or text — "front lower damper", "driveshaft nut", "bellhousing" — and get the torque instantly - Answers scoped to your car, so you only see the fixings that apply to your model and chassis spec (Imperial or Metric) - Bolt size and source on every answer — nothing taken on trust - Browse mode — read fixings grouped by system: front suspension, steering, differential, rear axle, engine and more - Figures in the manual's own units, including staged and angle-tightened bolts (e.g. "100 Nm + 90°") ENGINE-SPECIFIC TORQUES Crank, flywheel, clutch, cam-cover and bellhousing figures for the common Seven fitments: - Ford X-Flow (Kent) - Rover K-Series - Ford Sigma - Ford Duratec - Vauxhall (C20XE and 8V) - Suzuki Select your engine and you only see the figures that apply to it. BUILT FOR THE GARAGE - Works completely offline — no internet needed in the workshop, paddock or trailer - No account, no sign-in, no ads, no tracking - Everything stays on your device WHERE THE FIGURES COME FROM Torque and fastener data is transcribed directly from Caterham build and assembly manuals and engine manufacturer specifications, with the source shown on every answer. Where a figure isn't confirmed by a source, it isn't shown rather than guessed. IMPORTANT SevenSense is an independent reference tool and is not affiliated with or endorsed by Caterham Cars. Figures are reference guidance only — always confirm safety-critical torques against the official manual for your specific car. If the bolt size shown doesn't match the one in your hand, stop and check: you may be on a different spec. Published by RaceTracs Ltd.
