Thought I would pass this on. Just fitted chrome 17 inch Diablo racing wheels to my 2004 Classic. They are 7 inches wide. The tyres are Goodyear 215/50/17. The whole lot went on real easy and they filled the wheel well nicely. The effect on the speedo is negligable. The car now feels like it"s glued to the road on bends. The ride is slightly harsher but hey! who cares!!
The standard wheel is 15 inch.
