Just got a reply from
http://www.tqrcracing.com/ and he says they are about to start stocking the F109! Perfect, I bought my sakura from them, now I can buy more stuff from them!
another note, looks like since I put the F109 on our local track, its drummed up some interest in the F1s, but I have af feeling if we start a class we might go rubber tire on the carpet. Whats a good rubber tire for med grip carpet? Hearing about Rides alot on this thread but cant seem to find a particular post on carpet rubbers.
