I wasnt there for the mod day, but I ran the stock day... On my t4 I ended up with red ifmar rears with stock inserts (some peopel ran two stages) and silver losi directional fronts. In buggy and people with mf2's were trying cut holeshots but from what I saw they lacked sidebite... All in all I am pretty much sure the factory spec tire will not be one I will be running. And I dont think they will be really far off in 2wd or truck as much as 4wd...
