I’ve used NZKW Australia fittings and hose across two of my builds now for fuel delivery and oil cooler set up. When doing any further car mods these guys are my go to now! The team actually knows their stuff, which is rare these days and are always pleasant to deal with.

Not your conventional parts store where people make you feel like they’re doing you a favour. We’re talking about a shop that not only sells the things you want, but also provides you genuine advice out of real interest on the best outcome for your project. No matter if they end up not selling what you originally went to buy. Something unseen before shopping for motorsports parts.
They will spend genuine time to try and ensure you got the right parts, no matter how much you’re spending. For me that’s good character right there and their advice is backed by experience not by “I’ve heard of”.

Mike at NZKW Aus has been great, ordered me in some seat rails I couldn't find anywhere else. Was told 4 week wait and he smashed it in half the time. Thanks guys

Nick Smith

It’s refreshing to buy from people like Mike and his team that actually know there products and back them 100%, good quality products and fast shipping as well!

I grabbed a set of FIA ADR approved racing seats and a matched them with a seat rail kit for my track car. Fitment was spot on with zero hassle. The bucket seats are super supportive, lightweight, and street legal. If you're chasing proper performance parts in Australia, these are definitely worth checking out.

Great knowledge, product options and quality. Cannot fault Mike from NZKWaus. Just wish the lotto numbers come up for me so i can spend it all there!

I rang NZKW Australia with a last minute mission to fit a set of Recaro's in my tow wagon and Bride seats in my track car. They had all the mounts and seat rail kits for both vehicles, walked me through the easy installation process and difference in sliders and L brackets for each job. Amazing service and quality. Ill defiantly be back for some ADR seats in the future now seeing how easy and quick they make the installation of bucket seats.

I love the old school service at NZKW. Being able to walk in, get proper advice from the legendary Missile Mike and the team who really know their stuff — you just don’t get that much anymore. It’s unreal having access to high quality performance parts right here on the Gold Coast without spending forever driving around or waiting on online orders. Always helpful, always straight up. Highly recommend.

Drewe Jensen

I’ve been learning about performance upgrades my car and the correct use of aftermarket performance parts, and everything from the fuel delivery and oil cooler systems. The customer service and express shipping made it easy fast. Ill definitely be back more bucket seat mounts for my race seats. Thank you NZKW Australia.
