Automotive Parts FAQ
What materials are best for high-performance automotive parts?
Aluminium 7075-T6 is used for weight-critical engine components and suspension brackets. Aluminium 6061-T6 is standard for housings and structural parts. 4140 and 4340 steel are used for transmission components, shafts, and gears. Titanium is increasingly used in high-performance and racing applications for weight reduction. Material selection depends on thermal requirements, strength-to-weight ratio, and corrosion environment.
Can you manufacture one-off custom automotive components?
Yes. We specialise in single-off custom parts for performance upgrades, restorations, and custom builds. Whether you are modifying an engine bay, creating bespoke suspension mounts, or fabricating one-off brackets, we can manufacture to your exact specifications. Rapid turnaround and flexible tooling make small-batch and one-off production economical.
Do you work with motorsport teams?
Yes. We supply motorsport teams with custom components, engine modifications, and race-specific parts. We understand racing schedules and can turn around urgent components quickly. High-precision tolerances and lightweight material selection are routine for our motorsport clients.
What is the typical lead time for automotive parts?
Standard CNC machined automotive parts: 7–10 business days. One-off or custom components: 5–7 business days depending on complexity. Motorsport teams receive priority scheduling for urgent race-critical parts. Include your timeline in your quote request.
Can you reverse engineer obsolete automotive components?
Yes. We can reverse engineer from an existing part, creating detailed drawings that allow manufacture of identical replacements or improved versions. This is common for restoration projects, classic car rebuilds, and finding replacements for discontinued factory components.
What tolerances can you hold on engine components?
For non-critical engine components: ±0.05mm standard. For precision engine components like bearing surfaces or intake manifold ports: ±0.01–0.02mm. Engine blocks and critical tolerances should be specified on your drawing — we will advise on feasibility and cost impact of ultra-tight tolerances.
