  •  Great service. I’m very fussy with my vehicle and every time I’ve been here they have gone above and beyond. There price is on point to. As they say you get what you pay for. Very satisfying getting your vehicle back knowing the work is done properly and not having to redo things your self as I have done in the past from other so called reputable mechanical workshops in Perth – Jason Catalano
  • Many thanks to David and Matt for their experience and expertise getting my Hilux the extra power where needed, especially for towing. Locked In Garages heavy duty 1000nm clutch package, which includes the flywheel has made a big difference to the feel on the pedal and is so much lighter to depress than the so called heavy duty clutch i had in it from before. Also had bigger injectors installed, inlet manifold clean and remapping . Good job guys??  – Lyndon Kattler
  • Good honest prompt service.
    Just left it to them n they didn’t miss a thing.
    Vehicle has a heap of torque. I was really surprised at the result.
    I would recommend anyone due an EGR clean then see these guys n get the engine ECU remapped plus clutch etc at same time, u wont regret it.
    Will make towing the van n boat so much easier, they both weigh in at 3 ton each. – Alan Dodds
