OMP WRC steering wheel, in stock now in the Nottingham showroom.

This is the 350mm version with a 70mm semi dish and leather grip in black and red. Semi dish means it sits 70mm closer to the driver than a flat alternative, pulling the wheel back to a more natural position when your column is mounted high and forward. Rally cars and some road-converted saloons typically benefit from this geometry. Three-spoke black aluminium construction, 30mm oval grip section, horn included. Fits all standard OMP, Momo and Sparco boss kits

We've got one on the shelf right now. Cameron and Jack are here to talk through fitment, boss kit options, and whether the dish depth suits your car. Come and collect same day or we'll get it dispatched quickly.

Fitted a bucket seat in your Megane R26 and discovered you're now sitting somewhere near the sills? It's a common problem with direct-fit side mounts, they're clean and simple, but they sit you much lower than the standard seats ever did.

Our latest blog explains exactly why this happens, the key differences between direct-fit mounts and using a subframe with universal side mounts, and what each setup costs per side. If you're trying to find the perfect seating position in your R26 without compromising on safety or quality, this one's for you.

From fixed buckets for maximum track immersion to adjustable recliners with slide functionality, we've covered the lot. Worth a read if you're serious about your sim rig.

Sparco R330 Steering Wheel in suede, we've got two on the shelf in the Nottingham showroom right now.

330mm flat dish competition wheel with three-spoke aluminium construction and a yellow centre stripe. The suede grip gives better tactile feedback and grip when wearing gloves, which is why it's the standard for circuit and rally use. Flat dish means the rim sits at the same plane as the boss, the right choice when a fixed-back bucket seat already puts you close to the wheel.

330mm puts this on the smaller end, giving fast response without needing to move your hands far around the rim. Common choice in saloon racing, circuit sprints and track day builds where steering speed matters. Cameron and Jack are in the showroom if you want to see it in person, talk through your setup or arrange collection.

Fitting a harness in a VW Polo 6C without a roll cage is straightforward with the right approach. Clip-in harness systems from TRS, OMP, and Schroth mount directly to the standard seat belt anchorage points, offering proper four-point or six-point restraint for track days and spirited driving. These systems unclip in seconds, allowing you to restore full rear seat usability for daily driving without permanent modifications or fabrication work.

Our guide covers the QuickFit and clip-in harness routes that work with the 6C chassis, comparing the key options and explaining what to consider based on your driving style and vehicle usage. Ideal for enthusiasts who want improved safety and support without committing to a full cage installation.
