I have tried the LRP VTEC rubber tires and they don't really work on carpet tracks. good fun drifting around the place though
the 'wet' tires were the LRP Dunlop tires for wet TC tracks, still not great.
LRP VTEC foams are pretty dialled, but as has been said before, the Schumacher Rally Block in Yellow seems to be the alternative for a most 10th scale indoor off-road type track (with lots of slippy floor)
