Had left a sandstone and walnut wheel with Royal Steering Wheels in Aylesbury over the past couple weeks to get the sandstone leather replaced with Ash Grey (or their nearest alternative), as I'll be going to the all black, ZT-style interior soon.
I chose printed leather to match the airbag, although they do perforated leather and smooth nappa leather too, depending on your requirements.
Have attached a couple of photos to show how it's turned out. I'm quite pleased with it overall - nice tidy stitching. Only thing I'd advise would be to thoroughly tape up the walnut sections before sending off, as it came back with a small number of (admittedly very minor) marks here and there - not noticeable, in fairness.. they're probably not used to re-trimming wood wheels..
Expensive at £170, but will tie-in better with its surrounds once fitted
BTW, their website says they're very busy at the moment.
Cheers,
Karl.
