My experience has been quite different. 248rwkw and grip fine. Maybe the weight of the skyline helps. Dont get me wrong, they're not amazing, far from it. I was just trying to make the point that they're not an r compound.
In saying all of that, would I buy them again? Probably not. Truth be told, the only reason I did buy them is coz they where 150 a corner fitted in 265/35/18. Wallet was happy:) I think i'll be trying the rs3 next.
