Why Race Prep Matters

When your race car isn’t properly prepared, performance and safety suffer — and that could cost you the whole race.


Common Symptoms -


  • Struggling with last-minute issues before race day

  • Unpredictable car behaviour on the track

  • Setup changes that don’t make sense

  • Doubt in your car's reliability mid-race

  • Frustration over slow lap times or DNF results



Like your time and money are being wasted. Like you’re stuck guessing. Like you’re letting your team and potential down.



It doesn’t have to be like this.


You can have a race-ready vehicle that performs at its best from grid to finish.

Let’s help you take the guesswork out of your race prep.

Dave C., Attack Racer, Christchurch

"compliant weapon for historic events"

“They took my aging rally Escort and turned it into a reliable, compliant weapon for historic events. Can’t thank Quintin and the boys enough.”

Andy T., Historic Rally Driver

"I used to turn up to race day hoping things would work."

Now I turn up confident. These guys manage everything from setup to motor sports repair.

Turn Your Car Into a Race-Ready Machine

Plan It

We kick things off with a hands-on consultation to understand your goals, race discipline, and current vehicle setup. Whether you’re circuit racing, rallying, or tracking for fun — we map out the build or prep plan from the ground up.

Build It

From full race builds to fine-tuning existing setups, we get to work using race-grade components, custom fabrication, suspension and alignment tools, and dyno testing. Every detail is dialled in for safety, compliance, and performance.

Race It

We finish with track testing, adjustments, and — if needed — on-site race support. You leave with a race-ready car and the confidence to push it to the limit.

" Did you know"

Did you know most DNF failures are 100% preventable?

  • Over 65% of race retirements are due to preventable mechanical issues.

    Most "track-prepped" cars are rushed through generic checklists not tailored to race conditions.

  • Race day performance drops by up to 15%

    Race day performance drops by up to 15% if suspension, alignment and tyre heat cycles aren’t professionally dialled in.

  • What does that mean?

     If your race season matters, winging it isn’t an option. 


    Professional motorsport preparation ensures reliability, safety and performance from the green light to the flag.

What does that mean?


 Don’t wait until your next breakdown. Let’s build it right the first time.

We’re not a workshop. We’re a race-day weapon.

“Isn’t this just like any other workshop?”

Nope. Most workshops focus on road cars — we focus on race cars. Our builds follow motorsport standards, not WOF shortcuts.

“I’m not a pro driver – is this overkill?”

You don’t have to be a pro to want reliability, performance and safety. Our prep helps anyone racing — club, historic, hill climb or circuit — do it better.

    You don’t have to be a pro to want reliability, performance and safety. 


    Our prep helps anyone racing — club, historic, hill climb or circuit — do it better.

  • I already have a mechanic…

    That’s great. We’re not here to replace your everyday mechanic — we’re the race day specialists your setup deserves.

  • Can you work with my existing build?

    Absolutely. We’ll evaluate what’s working, what’s risky, and help elevate your current setup to race spec.

  • My local mechanic can do this

    Regular garages lack motorsport tools and know‑how. 

    We specialise in precision motorsport services that handle race stresses.

  • I don’t need trackside help.

    Without pit support, minor faults become race-ending dramas.

Not Just Customers — Race Partners

"I thought race prep was just a fancy oil change..."

Turns out, DCH Autosport prepped my car down to the bolt. Alex spotted issues two garages missed. Felt unbeatable.

Matt J. - Christchurch

"Didn’t think I needed race support until I did..."

Gearbox started whining mid-race. Sage were in the pits, ready. Back out in 10. Saved my day.

Nathan C. - Christchurch

"I assumed all prep was the same..."

Wrong. These guys use motorsport-grade parts, double check setups, and tune like pros. The detail is insane.

Common Questions from Track and Rally Drivers

  • Can you prep any kind of race car?

    Yes — from modern track cars to historic rally builds. If it races, we can prep it.

  • Do you offer one-off race prep or ongoing support?

    Both! We can do a full prep before your next race, or partner with you across a season.

  • How much does a typical prep cost?

    It depends on your car and goals. Some builds are a few hundred; full setups can be several thousand. 


    The first chat is free — we’ll give you honest advice and a clear plan.

  • Can I bring my own parts or work I’ve already done?

    Absolutely. We’ll inspect what you’ve got and integrate it into the prep plan if it’s race-safe.
