CNC machining for automotive & motorsport
From restoration projects and modified road cars to club racing and rally, automotive work is where CNC machining meets enthusiasm and engineering. Whether you need a one-off bracket, a batch of suspension components, or a remade part for a car the factory abandoned decades ago, machining gives you strong, accurate metal parts to spec.
What gets machined
Suspension components — hubs, uprights, brackets and mounts; engine and drivetrain parts — pulleys, spacers, adapter plates, flywheel and clutch components; intake and fuel parts — manifolds, fittings and throttle bodies; brake brackets and bell adapters; bespoke mounts for engine swaps and conversions; and obsolete parts for classic and restoration projects.
Materials
Aluminium 6061 and 7075 for strong, light components — 7075 where strength is critical, like uprights and highly-loaded brackets. Steel and stainless for high-load and high-temperature parts. Titanium for weight-critical motorsport. The materials guide compares strength, weight and cost so you can match the metal to the load.
One-offs, batches and reverse-engineering
Motorsport lives on small batches and one-offs, which is exactly where understanding CNC cost pays off — setup dominates a single part, so machining a matched set is often barely dearer than one. For classic and restoration work, a shop can reverse-engineer a worn or missing part from the original; bring the old component and any reference you have. See the cost guide for how quantity moves price.
Tolerances that matter
Mating and bearing surfaces, mounting interfaces and anything that bolts to a precise pattern need tight tolerances; cosmetic and clearance dimensions do not. Calling out only the critical ones keeps your quote sane — the tolerances guide shows how. Anodising adds corrosion resistance and a clean finish to aluminium parts.
