Performance Upgrades & Modifications

Performance modifications for European cars, engineered properly.

Onyx Prestige was founded by someone who genuinely loves performance cars. If you want to make your European vehicle faster, sharper, and more capable, you’re in the right workshop.

We approach performance upgrades holistically. More power means nothing if your car can’t put it down or stop it. We consider the complete system — engine, cooling, intake, exhaust, fuelling, transmission, suspension, brakes, and tyres — and recommend upgrades that work together.

We specialise in naturally-aspirated and forced-induction engine builds, ECU tuning (with reputable partners), intake and exhaust optimisation, suspension geometry for performance driving, and brake system upgrades for increased power levels.

What We Do

  • Engine builds (NA and forced induction)
  • ECU tuning via reputable partners
  • High-flow intake and exhaust systems
  • Intercooler and cooling system upgrades
  • Suspension and brake upgrades
  • Dyno testing and verification
  • Road and track testing support

Frequently Asked Questions

Will a performance upgrade void my warranty?

Performance modifications may affect factory warranty coverage for related components. We'll discuss this upfront so there are no surprises.

Do you tune cars on a dyno?

We work with trusted tuning partners who use dynamometer testing to verify power figures and ensure safe calibration.

What's the first upgrade you'd recommend for my car?

It depends on the car and your goals, but we often recommend starting with suspension and brakes before adding power. A car that stops and turns well is more enjoyable than one that only goes fast in a straight line.
