This is a good concept. My youngsters at Phoenix need something like this and it does make sense for a part of the hobby where this is aimed. Most if not all the SF members are clued up but many home racers are not and need help. If you go into a shop then the most advice you will get is "well yes you can have blue or red". What happens in this hobby is that the new home racer gets bored after a while and they need something like this to keep them in the game. I spoke to Luca at SCX about this major gap between high street buying home racers and those that race at clubs or who join in with us guys.GS and guys like Sean at Pendle are good at offering advice and with a test track in situ this is what a section of people need and I think well done GS! I don`t want wide wheels on my cars but then as explained it`s not aimed at me.
