Is it time to replace your race suit? Let’s get you track-ready. Sit in it before you buy it
Two and a half thousand square feet in Nottinghamshire, with over 125 bucket seats out on display, harnesses on a proper fitting rig, and racewear you can take into a changing room. Almost everything that goes wrong with buying motorsport safety kit online is a fitting problem, and a fitting problem is solved by sitting in the thing. Visits are by appointment so you get the time.
By appointment, Monday to Friday, 10.00am to 4.00pm, at Unit 5 and 6 High Hazles Road, Nottingham NG12 3GZ. Seat, harness and HANS fitting, racewear changing rooms, a free check of your existing harness setup, bespoke and contract seating, crash replacement and armed forces discounts.
What is on the floor
Stock from all three of our sites, in one building.
The showroom opened in 2012 and grew by another thousand square feet in 2016. We believe it holds the largest display of racing seats in the UK, running from the Sparco Circuit II, Corbeau Revenge and Cobra Evolution through to the Mirco RS2 and the Bimarco Futura.
Alongside the seats there are FIA harnesses, helmets for open and closed cockpit use, race suits, boots, gloves and Nomex underwear, HANS and hybrid devices, steering wheels, intercom systems and a set of big brake kits. Because the group sells seats on one site, brakes on another and racewear here, a visit covers all three at once.
Seat, harness and HANS fitting
Done in that order, because each one decides the next.
Bucket seat fitting
Everyone is a different height and build, and how a shell feels is personal. With over 125 seats on the floor you can work through them properly instead of guessing off a width measurement. We will get you into three or four that suit your build and let the seat pick itself.
Harness fitting in the Pro-Fit zone
We built the Pro-Fit zone for this. It has an in-store roll bar and a motorsport seat setup, so you can get your seating position right and then be belted in with a 4 point or 6 point harness. The angle your shoulder straps run at, and how they route through the seat slots, matters as much as which harness you buy.
HANS and hybrid fitting
With the seat and harness settled we go through the head restraint options. HANS and hybrid systems suit different disciplines and different shoulder widths, and the device has to work with the shoulder cut of your seat and the strap angle you have just set. That is why it comes last.
Fit decides what is comfortable. Your championship decides what is allowed. Homologation dating on seats, harnesses and helmets runs out, so bring your regulations or tell us the series and we will check what is accepted before anything gets ordered.
Racewear and helmets, tried on
There are changing rooms in the showroom, which is the point of the racewear side. Suits, boots, gloves, underwear and helmets are all out of their packaging and on display from the brands we carry deepest, Sparco, OMP and Alpinestars among them.
Try a suit on over the Nomex underwear you will actually wear, because the underwear changes the fit and sizing a suit without it is how people end up with something too tight at the shoulders. Helmets want trying indoors: once one has been worn outside it cannot come back.
Once you have settled on the pieces we will put the whole lot together as one package rather than pricing it item by item.
The free harness safety check
Sitting correctly, with the harness at the right angle and routed properly through the slots in the seat, is the difference between walking away from an incident and being hurt in it. Plenty of setups we see are wrong, usually because the shoulder straps run at the wrong angle or the belts have been fed through the nearest hole rather than the right one.
If you are not sure yours is right, bring the car in or send photographs and we will check it. There is no charge and nothing to buy at the end of it. If your setup is fine we will tell you that and you can go home.
Also in the showroom
Not everything on the floor is a seat.
01Steering wheels
Wheels from OMP, MOMO and Sabelt among others, out where you can feel the grip, the dish and the diameter before choosing. We list 2,307 steering wheel and accessory lines including 2,169 boss kits, so fitment for your car is rarely the problem.
02Roll cages
We work with Safety Devices and Custom Cages through to Sparco and OMP. Whether you need a track day, Motorsport UK or FIA cage changes the whole specification, so tell us what you are entering and we will tell you what will pass.
03Big brake kits
A range of kits on display, which is more useful than it sounds when you are trying to picture a 356mm disc behind an 18 inch wheel. We match the kit to power, weight and wheel size rather than to the brand you arrived thinking of.
04Bespoke designed seats
Working with Cobra and Corbeau we can build a seat to your specification. A fully customised motorsport shell with team logos, or a diamond quilted trim for a road car. Bring colours, a logo or a photograph of what you are after.
Bespoke and contract seating
Racing seats end up in a lot of places that are not race cars.
A motorsport shell trimmed properly is a good seat for anywhere people sit for a long time, which is how this side of the business started. Past projects include Nike, Partick Thistle FC, MSV Explorer and Blackberry. Each one is quoted individually, with a package built around what was asked for and a time plan for the work.
Specialist services
Three schemes that are easy to miss and worth knowing about.
01Crash replacement
If your last session did not go to plan, register the incident with us and we activate a 10 per cent code across all three sites, valid for six months from the date. It applies whoever you bought the original equipment from. Rebuilding a whole car is better done on the phone than through a code, so ring us for that.
02Is your helmet in date?
Nine helmet standards are accepted at Motorsport UK national events in 2026 and only one of them has a date against it. Snell SA2015 is not valid after 31.12.26. The guide covers the full list, the ASN sticker, and the separate rules for juniors and karting.
03Armed forces discounts
Ten percent off for serving members of the UK armed forces, reserves and veterans, covering racewear, seats, harnesses and big brake kits across our sites. Partners are covered too. There is nothing to sign up for: mention it when you ask for a price and have your Military ID ready.
Booking a visit
Appointment only, and there is a good reason for it.
Appointments mean the time is yours. Garreth normally takes the fitting himself, going through your build, how you drive and what the car needs before anything comes off the shelf, and then narrows it down to a handful worth trying. That does not work with people walking in on top of each other.
Tell us roughly what you are after when you book, so the sizes are out ready. If you are coming for a harness check, bring the car.
Unit 5 and 6 High Hazles Road, Nottingham, NG12 3GZ. Centrally placed in the Midlands.
Common questions
Do I need an appointment?▾
Yes. The showroom runs by appointment only, Monday to Friday, 10.00am to 4.00pm. It is not us being awkward: a seat and harness fitting takes real time, and booking means the sizes you asked about are pulled out ready and nobody is interrupting. Book at calendly.com/gsm-performance or ring 0115 9893488.
How many seats can I actually sit in?▾
Over 125 are on display at any one time. That is the whole reason to come. Fit is the thing people get wrong buying a bucket seat online, and twenty minutes moving between four or five shells settles it in a way no size chart will.
Can I try racewear on?▾
Yes, there are changing rooms. Suits, boots, gloves, underwear and helmets are all out of their boxes. If you are buying a suit and Nomex underwear together, try them on together, because the underwear changes the fit.
Is the harness safety check really free?▾
Yes, and there is no obligation attached to it. Bring the car or bring photographs of your current setup and we will tell you whether the belt angles and the routing through the seat slots are right. If it is fine we will say so.
Do you fit the equipment to my car?▾
We fit and set up in the showroom so you leave with the right size and the right specification. We are a supplier rather than an installer, so cage and brake installation goes to you or your garage. We will tell you exactly what the job involves before you commit.
What do I need to bring?▾
Your regulations if you are competing, because dating and homologation decide what is allowed before fit does. Your existing seat, harness or helmet if you want them checked against something new. The car itself if you can, especially for a harness check.
Can you sort seats for a Nurburgring trip?▾
We used to rent seats for it and we no longer do. Check what your session actually allows with the circuit or the organiser, because those rules have moved more than once, then bring us the answer and we will sort the seat. We hold fitting kit data for 812 named cars, so we can tell you what bolts in before you spend anything.
I have had an accident. Do you do anything for that?▾
We run a crash replacement scheme. Register the incident with photographs and we activate a 10 per cent code across all three of our sites, valid for six months from the date. You do not have to have bought the original equipment from us.
Do you do armed forces discounts?▾
Yes, for serving members, reserves and veterans, and partners are covered too. It applies to racewear, seats, harnesses and big brake kits across our sites. There is nothing to sign up for. Mention it when you ask for a price and have your Military ID ready.
Where are you?▾
Unit 5 and 6 High Hazles Road, Nottingham NG12 3GZ, centrally placed in the Midlands and a few minutes off the A52.
Book a slot and bring your regulations
An hour in the showroom settles fit, sizing and what your championship will accept, which is most of what goes wrong buying this kit online. Bring the car if you want the harness checked.
