The New showroom is taking shape slowly but surely.
It is such a pleasure to be able to open up the doors to the public again, the amount of mechanical "walk-ins" has shown us that it truly is important to have a show room.
Hopefully in the coming weeks we will get our waiting room up and ready so we can better accommodate the service people as well and provide a higher service experience.
Alot of people travel from all over Perth to use our services and we truly want to show our appreciation by giving back with a better waiting experience.

In the mean time, you can just check out the eye candy in the wheel show room! With perths largest range and most comprehensive stocking of wheels, we are your one stop shop for all things HSV, Holden and SRT. !

With the economy running away (who knows what direction) we felt it time to address our LS platform costings and speak to our suppliers to ruffle some feathers.
What we ended up with, is ultimatltly an over-all relatively close pricing structure.

This means, moving forward, RJM can still offer our tried and tested packages at competitive prices. Tuned in house on our 3000hp Mainline hub dyno, or our 600hp dyno dynamics chassis dyno with Before and after dyno results available.*

Drop our team a message to book your Vehicle in, or pop past our new showroom at units 4- 5 / 13 Alex wood drive Forrestdale 6112.
Have a chat with our team to discuss your package requirements and lock away your dates.
With Perth largest range of HSV wheels in stock, you might just pick up a set of wheels why you're there. 🤩

CAMSHAFT PACKAGES AVAILABLE FOR PURCHASE SEPERATLY IF YOU ARE HANDY.

🚀 What sets us apart is our relentless pursuit of improvement.
This is Jack's 2015 SRT Jeep.
With a relatively small change to optimise the camshaft position, we saw a dramatic reduction of approximately 3.5psi of boost pressure, with no loss in overall power.
Put simply, optimising the valve events allowed the engine to utilise that airflow more efficiently, rather than turning it into heat and backpressure. The result is a more efficient combination that works smarter, not harder.
We're constantly working to ensure our range of HEMI camshafts performs at its absolute best. Development never stops. We work closely with some of the best minds in the country, discussing data, modelling airflow, challenging theories, testing ideas, and then heading straight back to the drawing board to refine and improve.
One small tweak at a time.
A huge thanks to Crow Cams for custom grinding the revisions, allowing us to test, validate and provide real-world feedback that helps further refine the product for HEMI enthusiasts around the world.
This isn't theoretical camshaft design. This is development backed by real vehicles, real testing, real results, and continuous improvement.
