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.
We prep cars for serious track, rally, and race use.
We’re not just tuners — we’re racers too.
At DCH Autosport, motorsport is in our blood. Owner Quintin Baker and our team bring decades of hands-on motorsport experience, from classic rally cars to time attack and club-level racing.
We understand the pressure of race day, the challenge of prep, and the demand for excellence.
We don’t just build cars. We build confidence.

"the only ones I trust to touch my cars'
"I’ve raced everything from classics to club circuit cars and Quintin and the team at DCH are the only ones I trust to touch my cars. Precision prep and real race knowledge."
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.

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.
