Thank you for your support

We want to thank each and every one of our customers for supporting our small business during these difficult and unprecedented times. Since March we’ve had to close our showroom twice, for over 4 months during 2020. We had to act quickly to continue operating our processes from home, and work around government guidelines to keep our team, and our customers safe. 

Simply put, we appreciate every single order we receive from you. 
Your orders are vital to helping businesses like ours work through the pandemic. 

Looking after our industry

We work hard ensuring we can keep supply flowing. We do this by working closely with our manufacturers. Each one produces our specialist products and now faces doing this with a range of restrictions in place. Social distancing in manufacturing has reduced the work force and production capacity. This has resulted in lead times extending with a range of products in our industry. 

However, by working side by side with every distributor and manufacturer, we ensure that every customer is fully informed of lead times, along with production and delivery schedules. 

Thank you. Race safe and stay safe

We have a premium range of over 125 seats from brands including: Bimarco, Cobra, Corbeau, Sparco, OMP, Recaro, GP-Race, and Bride to name just a few brands we work with.
