The rugby ball wheel is poor, its got horrible cheap leather, consequently has low grip and is too big and is ugly, moving to a good quality 350mm MOMO or equivalent wheel makes it so much better to drive. I couldn't wait to remove mine on my Cinq, and mine was a rare Cinq fitted with air bag. I had a beautiful Abarth steering wheel I bought from Italy which was brilliant.
My personal favourite at the moment is the re-released MOMO Prototipo wheel, very tempted in one for my integrale but have a rare MOMO Martini racing wheel on there now and seems a shame to remove it.
