Semi runs 63mm to 72mm and it is the smallest group we sell, seven wheels from Sparco, OMP and Sabelt. The dish we fit most on a plain boss, and why a 70mm OMP and a 70mm MOMO end up in different guides.

The Stilo Venti4 Trophy Jet and Trophy Plus Rally both carry FIA 8859-2024 and Snell SA2025, the newest approvals available. With Snell SA2015 helmets expiring at the end of 2026, Cameron looks at both, plus the new DG-20 Raid amplifier and the adaptor lead you cannot run it without.

Cameron’s walk round Gravity Show 2026 at the NEC, the ten year anniversary edition: a chrome Veyron, a matte P1, a Renault Formula One car, a hall of Skylines, a Gullwing on the floor, a 190E Evo II in DTM colours and thirty three photographs of what he saw.

Flat means 0mm: the rim sits level with the mounting face on the boss. Every flat wheel we stock from OMP, MOMO, Sparco, Sabelt and Reverie, with dish figures, diameters and prices, plus why flat is the one to buy behind a quick release.
