Got my wheels powder coated and they look like completely different! Exactly what I was going for and I absolutely love them.

Took my vehicle in for a XHP gearbox remap and stage 2 engine tune, While my engine was slightly underpowered as stock these guys still managed to get me a very pleasing extra 185bhp. The car is running amazingly smooth and I was assured upon arrival that the car will be taken care of and not pushed over its limits to ensure the wellcare of my engine and that they have delivered.

Many thanks to the lads down at ONYX for taking care of my vehicle.

From enquiring on the phone to receiving my car back every element of the service was extremely professional and thorough. A great place, didn’t feel intimidating being there so I was happy to wait for my car on site. Thank you for a great experience. Il be back for the car service next time.

Came in for 3 diamond cut BMW alloy refurbs, left a happy man. These guys are friendly, knowledgable, and I’ll be checking out their other services in future. Great looking workshop, tidy and productive - and they’re happy to explain everything they’re doing in depth. Great communication.

The wheels? I had 3 done. They look brand new, and one was really heavily corroded. Recommended!

Had 3 of my cars tuned here . First my a class . Then my 440i and now my c63 to stage 2. Very good service and very friendly always looked after me. Highly recommend.

Took my Abarth 595 Pista to these guys today for a Stage 1 remap. I enquired at a few tuning workshops over the last couple of weeks but Onyx stood head and shoulders above the rest in terms of facilities, knowledge and customer service. As for the remap they did......All I can say is WOW. Incredible transformation and exceeded my expectations as far as power/torque increases. I can 100% recommend these guys.
