Splitter Replacement for Mercedes C250d
Just finished replacing the splitter on this Mercedes C250d! The customer supplied their own splitter, and we got it fitted with care. Always great to work on such classy rides.

We’ve been quiet for the past month.

Had a lot going on behind the scenes and needed to take a step back.

But we’re back 🔧🔥

First job back in — Audi S3 8V in with EPC & EML on.

Full diagnostic carried out ✅
Chain lengthening & cam correlation faults detected ⚠️
Cylinder 1 misfire present

This is why proper diagnostics matter — not just clearing codes.

Bookings are now open again.
Let’s get your car sorted properly.

This car right here isn’t just metal, bolts, or horsepower.

This is where everything started.

Before the late nights. Before the customers. Before the logo, the posts, the bookings… there was just me, this car, and a genuine passion for learning, fixing, modifying, and pushing things further than stock.

I didn’t start with everything figured out. I started with curiosity. Watching, learning, making mistakes, fixing them — and slowly realising that cars weren’t just a hobby for me, they were something I wanted to build a future around.

This car taught me patience.
It taught me discipline.
It taught me that progress doesn’t happen overnight — it’s built through consistency, graft, and belief when no one else sees the vision yet.

From working on my own car, to helping friends, to now building something bigger step by step… this journey has been unreal. Every remap, every install, every late finish after a full day at work has all led to this moment.

I’m proud of how far I’ve come — but I’m even more excited about what’s next. This is only the beginning.

If you’re building something from the ground up, keep going. Trust the process. One day you’ll look back at where it all started and realise it was worth every second 🤍
