I was just reading Gabriel's conversion thread.
Very interesting. I'm at work, so I'm really just browsing through it.
I just thought about it since I don't go off road (yet) and wondered if I could do a cheap retrofit (with 2nd hand wheels). Mainly for looks and easy of cleaning (but if it improves street handling, the better)
It does seem to be a tad more complicated than just bolt off, bolt on.
