📌 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.
