I love a thicker steering wheel and a simple way to do it is with a steering wheel cover. I have done this mod a number of times on previous cars with great succes, and this one worked out great as well. Very happy with the result, as it gives way more grip.
On pictures it looks like a big color difference, but in reality its not that bad. I have chosen a black inlay and black yarn, as a color would look out of place.
