Padaily foam is fun easier to drive and a lap or to faster. Its really a good way to go a little faster. There sure is alot of talk. Rubber or foam? I myself I prefer foam with my brushless thats about all i have ever run. At our track civic 91 made a great point, that with rubber the brushless on carpet may have to much grunt . I guess maybe to hard on diffs or something. I'm sure he'll be around sometime. maybe he can comment? I'll say this rubber is a great way to afford a better paint job.
