About Us

Your RenaultSport is your pride and joy.

You spend time cleaning it and making it gleam.

You spend money adding your own personal style to it.

You want it to be at peak performance round every bend, and at every braking point, every country lane, and every track day.

When it comes to servicing, MOTs and Parts you want a company that knows your RenaultSport inside and out.

How do we know this?

"Because it’s what I want for mine, and that’s why I started ALS Performance Ltd."
Barrie Thomson, owner

We may be a fairly a small company, but we have a big knowledge and a big reputation for attention to detail. Barrie Thomson, owner and founder of ALS, grew up surrounded by Motorsport: Rallying, Karting, Single-seater racing. His love of Motorsport sent him on a career path that would take him to all four corners of globe with the World Rally Championship. He was working for Brawn GP the year they clinched the Formula One Constructors and Driver’s Championship. After years spent traveling he decided it was time to settle down, back in his home town and start his own business. That’s how ALS Performance was started.

We started out in a small unit just outside of town, breaking a RenaultSport Clio 172. Blood, sweat, and thankfully not too many tears later, we now have a large bright, clean modern unit in the heart of the northern business district of Carlisle. We have state of the art equipment for servicing, MOTs and general repairs. We haven’t forgotten our Motorsport roots though as we are now the Michelin Clio Cup Race Series official parts supplier. You can find us trackside at every round of the championship, or on the end of the phone giving parts advice.

ALS Performance is based at 44 Parkhill Road, Kingstown Industrial Estate, Carlisle, Cumbria CA3 0EX. We’re just off the M6, easily accessible from the North West, North East and Southern Scotland.
