We’ve been best known for our range of bucket seats. Over the years building up some of the most valuable knowledge within the industry.

By handling the products we sell in-store, we have hands-on experience meaning we can help you with any questions you might have. We can even provide an in-store service testing seats to get the right fit for your requirements

Working with over 60 of the world’s biggest brands, we are able to display the very best from TRS and Takata through to Luke and Schroth. 

We worked with BBC’s ‘Fake Britain’ to help in the war against counterfeit products. 

Our #Safetyfirst philosophy extends to performance brake kits. We have our dedicated range of brakes from K-Sport through to HiSpec. 

With great power comes great responsibility!  When you hit each corner you’ll appreciate the right set of brakes keeping you on the track and stay racing safe.

Our history in detail...

Trust in experience

A passion for what we do, constant weekly training and customer driven improvements, keeps us focusing on what really matters in this industry. You. 

When there’s so many online companies looking for your business, trust in GSM Performance to give you the service you deserve. 

Established in 2003 by myself (Garreth Sleigh), my original plan was to help build, modify and customise cars to a standard high enough to be featured in various magazines including Redline and Fastcar. Over the years, we supplied parts and customisation options for hundreds of vehicles.


We then started to move into the performance parts market, even racing our performance Subaru Impreza track car and TVR T350c. This gave us an insight into the new direction of GSMotorsport and how we needed to evolve with the changing market. Over the years with our growing experience dealing with performance and modified cars, we realised that it was time to make a change!

We understood that customers buying certain products demanded better customer service, product knowledge and choice than was currently available. As a result, we focused on retailing specialist high-value parts where we could bring our experience to the table. 

We believe that providing three websites distinguishing between the product ranges allows us to provide you with a better service. Each website is able to bring you the most up-to-date and accurate information regarding each set of products. With information guides and fitting guides to accompany the product line-up, we feel that these websites bring the best that we have to offer.

In 2012 we opened our GSM Performance showroom taking our service to the next level. We have a full display of Motorsport seats, big brakes conversions, and harnesses. In fact, we have the largest display of racing seats and Motorsport seats in the UK from the Sparco Circuit II, Corbeau Revenge, and Cobra Evolution through to the Mirco RS2, and Bimarco Futura racing seat. The opportunity to sit in all these seats is not to be missed!

Over the years we are proud to say we are now supplying bespoke race seating for customers that now include: Nike, Partick Thistle FC, MSV Explorer, and Blackberry to name a few high profile clients. In each case, we provide a fully tailor-made quote and package to match each customer’s exact requirements. We then provide a detailed and accurate time plan and project plan every order to ensure our quality of service.

My one goal was to constantly ensure that GSM Performance provides a high level of customer service that surpasses all expectations. As the markets have changed over the years, we’ve changed with them. Each month, we adapt to customer requirements and I truly believe this is the key to continuing to excel at what we do. 

I’ve carefully selected my trusted team taken on a new apprentice each year to support our local community. With continued product training and hands-on experience in our showroom, we are able to handle all your enquiries with a personal approach. This allows us to ensure you’re completely satisfied with our service from quotation to delivery.

In 2014 we have decided to bring you our all new product video reviews. No one else in our market has done this yet so we felt it was the time you could view each product we sell via our YouTube channel. Reading about each product is great, looking at the photos is fantastic, but watching our reviews on YouTube is the next step to providing you with a full customer experience.


In 2015 we have expanded our goal. Putting your safety first! We now focus on all equipment that keeps you safe during all forms of Motorsport. Alongside Motorsport seats, harnesses and roll cages we now sell racing suits, helmets, gloves, boots, and everything else you may need. This has been an exciting development and these products can now be found online.


In 2016 we extended our showroom by another 1000 square foot and increased our stock holding. Our new showroom not only brings you the seats and harnesses previously on display, but we also stock an extensive range of all the race-wear that we started to sell in 2015.


In 2017 we focused our customer service experience, for the entire year, week by week & month by month, we worked to look at all our processes from ordering a product through to delivery, and then streamlined every step throughout this process. We then added new features, from SMS text updates through to supporting articles & documents for products (where the suppliers had not provided enough information). We feel that 2017 was a turning point for how we handle each and every enquiry to be the very best in the industry.

With each passing year, we bring increased services with better support and satisfaction without losing our personal small business approach. We strive to keep it that way and keep our customer satisfaction ratings high.
