The steering wheel on the old zebra fj40 has been a source of irritation. Once I got power steering I didn't need a giant steering wheel to get the beast moving in the right direction. So I replaced it with a 13" steel dune buggy wheel. I didn't really think about the dish of the steering wheel but, as you can see from this picture, it was pretty deep.
With the roll cage I can't move the seat back and at times I feel like I'm hunched over the black wheel. So, I picked up a flat aluminum wheel from Chirco. Being aluminum it's light and it does look a bit like a go kart wheel, but the rivets on the back give you a really good grip.
so far so good! I'll keep you posted when I give it a thorough testing.
