About the LCG... I donīt think that the price anounced by Yokomo Japan is too high. Look... you get nearly a complete new car. The only things missing are:
-steering knuckles, c-hubs, rear hub carriers
I donīt think you need more parts. Tell me if I forgot something.
All this parts together cost... hm... 120$??? 200+$ for the conversion + 120$ for parts and you get a new car. In my opinion this price isnīt high.
And did you looked at the prices for the SSg/Black Special at the Yokomo USA site? 528$!!! Where do you pay this price???
