G-R Performance LTD

Took my Subaru in for mapping after having it previously “forged” got a call less than an hour later to explain something had gone wrong so left the car at g-r for diagnostic and they found out the engine wasn’t built correctly so they stripped it down and rebuilt with actual forged parts, new ecu plus a multitude of other thing, they was so helpful and kept me updated all the way through (even during covid and moving premises) there aftercare service is something else, I would never go anywhere again g-r for the win would 100% recommend

I’m New to Evo’s and needed some help & advice, found James very helpful, extremely knowledgeable & kept great communications throughout the work needed. So far so good, happy customer ! Thanks Guys !

Had bits done by the guys here recently and used their RR a few times. All 10/10, huge knowledge, friendly and honest.

Spoke to the guys at Gr performance. Was very helpful getting my subaru impreza booked in for a map check, a professional and honest service explaining what they was doing and looking for. Would highly recommend anyone to use them and I will be doing so in the future.

Can’t thank these guys enough, had my evo remmaped and new pipe work fabricated in house. The welding quality is superb the knowledge these guys have is unbelievable and the i now have a completely different car, great power but smooth and feels much happier on the road. They have a great sense of humour but also a fantastic team that work like clockwork, they all know exactly what the other is doing and it has been a pleasure from start to finish doing Buisness here, needless to say I will be returning for more upgrades this year, bearing in mind this is a 500 mile round trip for me I would travel many more miles if it meant I would get the service that I have received. Top marks, and many thanks from a very very happy customer 👍
