Hello, Anyone around here that has experience with these tyre's? I'm looking for some relatively cheap track tyres, was planning to go for either the 595 RSR or the NS2R, but from what i've got to understand the compound of both the NS2r and the 595 RSR had to be changed because of new regulations, and now they are not that good anymore. I've been looking around and found these 2 tyre's. Anyone around here that has used these tyres, and could tell me more about it? Thanks in advance.
