This week we’ve had plenty in, here’s a couple!

• Toyota Supra in for suspension all round & diagnostics on a knocking noise, booked back in to have the steering bush replaced next week 👌🏼

• BMW E92 in for a service, oil level sensor, rear brakes and a general health check to make sure she’s still ready for the road and track 👊🏼

• BMW M2 new vented carbon wings fitted.

• We’ve also had in a Megane for a map, Porsche for a diagnosis and a Clio in for a full recommission, the Clio was poorly & had been off the road for 5 years so needed some serious TLC, rebuilding the cylinder head, replacing the top end gasket kit, carrying out a major service including cambelt kit, resolving a misfire, cleaned the injectors, cleaned up all the brakes, repaired the exhaust and generally made sure she’s good to pass an MOT.

Diary is starting to fill up, if you want to get booked in please drop us a DM. Winter is on its way! 📩 🥶

This is rare 💎
As most of our customers know, our lead times are usually 3-4 weeks which we know can be frustrating, with the summer holiday lull now over and work starting to pick back up, we’re currently at a lead time of around a week.

For maintenance, modifications, cambelts, conversions, bearings, crank hubs - whatever you require, drop us a DM and book in before the madness starts again 👇🏼📩
