I taped some foam on to the steering wheel then fitted the same sort of cover.I think it will fit in exactly the right place. Bear in mind that the series 3's have a steering lock and the horn isn't located in the middle of the steering wheel. Is there a reason you want to change the steering wheel? The series 3 steering wheel is much more pleasant than the series 2 types. What made a difference on my series 2 was a cheap lace up steering will cover for £6 from eBay. A bit more comfortable and no black dirty hands on cold mornings when arriving at work.
