The final days before the reveal. 🏁

Wiring, fitting, adjusting, bleeding brakes, alignment, testing — and still finding little things to improve along the way.

A big part of our team has been involved, and this project has already given us more stories, challenges and laughs than we could fit into one post.

We’re not showing you everything yet.

Just a few more days before the real testing begins. 🖤

No more teasers — here`s our livery. 👀

One legendary race car gave us the starting point. We took it from there.

Any guesses? 👇

The E46 Compact is going to look wild. And you`ll be seeing these colours a lot more often. 🔥

Yes, but… let us explain. 👀

#yesbut #explain #cncengineering #racecarbuild #context ...

Small 3D-printed details made to keep our E46 Compact body clean and tidy, prevent anything from rubbing through, and make everything look extra smooth and satisfying. ✨

This time we made a few small but important parts:

– a firewall piece that holds the steering axle rubber boot neatly in place;
– a brake line pass-through for the firewall, so the lines stay properly positioned and protected;
– a fuel hose bracket that bolts directly to the body, keeping everything stable and stopping the hoses from moving where they shouldn’t;
– plastic window holders inside the doors, keeping the windows securely in place.

They might look like small details, but these are exactly the things that make the whole build feel clean, safe, and well thought out. When every hose, line, rubber piece, and bracket has its own proper place, everything starts to come together exactly how it should. 🤌

Feels like we’re slowly building a unicorn. 🦄

ATTENTION ❗💥

Shifter selector rod end. Machined from metal, in-house.

Solid throughout — nothing in it to soften, harden or crumble. Direct swap, works with the OEM selector rod. Fits manual BMWs from the E36 up.

NP Parts Front Main Control Arm

Since this is our own NP Parts build, we wanted to put all our crazy ideas into action and test them properly.

Inner mounting point:
Most kits on the market use a design that mounts this point lower than the original control arm, resulting in even worse roll center geometry.

Our design has an inner mounting point 11.5 mm higher than the original BMW control arm.

Camber adjustment:
We designed a shim-based camber adjustment system. This makes it faster and more convenient to set both arms equally and precisely.

Overall arm design:
We made the arm stronger and lighter by adding material where it is needed and machining more material away from areas where it is not.

The new design is also more resistant to side impacts.

Built to test our ideas properly — and push the suspension setup further. 🏁

WE BUILT ARMS SO STRONG, THE REST OF THE PROJECT HAS TO KEEP UP. 💪

You already know the car.
But where we’re taking it, what we’re building it for and what kind of madness we have planned — that part is still classified. 🤫

Starting with these CNC-machined 6082-T6 billet rear control arms, featuring 30 mm of adjustment and motorsport-grade spherical bearings.

And because normal was never part of the plan, we also manufactured offset rear trailing arm bushing mounts with motorsport-grade spherical bearings — a rare setup designed to increase rear toe adjustment range, eliminate rubber-bushing flex and keep the rear suspension geometry under control during hard cornering, braking and acceleration.

‼️Less unwanted rear steer.
‼️More stability.
‼️Sharper response.
‼️More freedom to dial in the exact camber and toe setup this machine needs.

Did we make the strongest arms on the market?

We’re still not saying yes…
but we’re definitely not saying no. 👀

Prototype. Two functions, one part.

There`s not much room behind an E46 front bumper, so we stopped treating the brake duct and the light as two separate problems. Now they`re one piece.

Fresh air goes straight to the brakes. The same housing carries the endurance-style LED light.

No extra brackets. Nothing bolted on top of something else. It sits behind the bumper and does both jobs.

This is the first one off the machine. It goes on the car next — and whatever testing tells us ends up in version two. 👀

It reaches the e-shop when we`re happy with it, not before.

What would you change before we make it final? 👇
