Yes, good grip, don't pick up muck from the track and I have never managed to wear out a set so far. I have some cars still running on five year old tyres. I have never found any urethanes that give as much grip as treated NSR ultras but they are way superior to the major manufacturers' box stock tyres.

Some say that treated nsr tyres ruin grip for other brands , and here they are not allowed on our group of private tracks. We only run untreated brm, slot it rubber or mjk urethane tyres.
