Greeny, do it!
I did it ater 12 years or so o on road, of road it so much cheaper, and its deinatley harder and you can only drive at about 80%
Its so much more fun. If you go for one of the BJ4 clones you will be fine.
You dont need a set up system at all!! so sell it
Just get some wish bones and shock towers and maybe a set of hubs and you will be good to go.
This will be the best move you make and wont regret it
