Given that they are direct from Renaultsport i wouldn't imagine they will be selling bad quality wheels. The only thing that confuses me is why they offer two versions and neither has the makers stamp on the front (although more than likely Sabelt as i believe they make the current Cup Racer steering wheels).
If in doubt then look for one of the 'proper' Sabelt cup racer wheels, or sparco versions if you can find them.
