I know you are on the investigation about the sports steering wheel and spoke thickness. You mention in another thread that the Rare Spares version is always the 3mm thin spoke and they claim it is ADR approved for all models etc. Even though really it should be correct for later HZ only. Another issue with the Rare Spares version is the boss kit. It differs wildly from original. I guess this isn't an issue if you are only replacing a wheel but if you need a complete assembly you are nowhere near correct for any HQ to HZ. Although it gives the untrained eye the "illusion".
