📌 By Appointment Only. 📅

We have A lot of work booked in at the minute and there’s only so much we can do as a super small team.

These are a rough guideline of our lead times at the moment.

If you want booking in - please DM our FACEBOOK page and we can give you accurate availability/cancellations etc.

Please do not:
• Just drop in for us to take a look at the car
• Call in for a chat about your car and take me away from my work for half an hour/an hour.
(I need to get jobs done, i work on a very tight schedule constantly to maximise efficiency.)
• Presume you can just drop your car off or have it recovered to us and it be worked on immediately if you are not booked in.
• Expect on demand diagnostics/plug in.

BOOKINGS ONLY.

Thankyou for your cooperation!🤟🏼

Swipe to see the rebuild.

One of our customers had a bit of a fire on a track day due to downpipe bolts snapping due to heat expansion, that caused a whole big mess. A melted loom & a damaged engine, it was time for a full strip down and rebuild. This list is just a fraction of what has been carried out on this car but we’d be here all day!

• Full strip down and removal of the old engine and everything burnt.

• Replace all Fuel lines, brake lines, vac lines, coolant pipes, brake lines, master cylinder, fuel lines, bushes, ABS Pump & lines.

• Rewire engine loom, bulkhead loom, abs loom.

• Full tunnel & engine bay heat shielding

• Refreshed and fitted meg 250 engine
Painted engine and ancillaries and refreshed steering rack.

• 3” down pipe with link pipe & mapping.

Evolution 🛠️

As a lot of Renault Sport parts are becoming obsolete and harder to source and too many “fake” parts available which fail and we cannot warranty, we are trying to phase them out slowly.

We will do our best to keep going whilst we can but there is a supply and demand issue that we are facing and it is making our business very difficult to continue that way.

Hope you can all understand our evolution and what we are trying to achieve to help the business move forwards.

(We do not and have never worked on diesels)

As always PLEASE DM TO BOOK.

Thankyou.
