I have NS2's and they're okay. I bought them as old set of wheels got corrosion in the rim and went through three tyres in 2 months so bought those as a temp thing. In the dry they work, they're hard wearing. Launch at higher than 3k rpm and they will spin and if you land 1st to second in lift they will spin again. In the wet and snow or anything other than dry, they spin. Controllable under normal driving but if there's a moment where you need to stop suddenly or turn sharply in anything other than hot dry weather you will shit bricks.
I won't buy them again, they last forever, but that's a lot of thinking time about what else you could've bought.
