Performance modifications

From timeless classics to high-performance supercars, every car gets the same attention to detail, passion for excellence and precision workmanship. Upgrades are tuned and proven on the rolling road.

How we approach a build

The best modifications feel like the car always had them. We plan carefully, fit properly and prove the result.

  • Plan the build

    We agree what you want from the car, how you use it and where to stop, and we keep changes reversible wherever we can.

  • Fit with care

    Precision workmanship: the right parts, fitted to a high standard and checked over before anything is started up.

  • Set up and tune

    Mechanical set-up and calibration are checked under load rather than assumed.

  • Prove it

    Before and after runs on the rolling road show what the changes have actually done.

Who it's for

Fast road and track drivers

Collectors

Careful, well-documented changes for owners who care how the car will be seen in future.

Every modification is on record

A clear record helps you, and whoever owns the car next.

Questions

Will modifying my car affect its value?

It can. Well-chosen, well-documented and reversible changes tend to be better received than heavy alterations. We will talk through the options and keep records of everything we do.

Do you work on British cars as well as Japanese?

Yes. Japanese and British sports cars are both our speciality. Tell us what you have and what you would like to do.
