Not really, you dont have to dig it in, just peg it down with wire loops about the same thickness as coat hanger wire and the grass will grow through it. Doesnt have to be everywhere, just the areas that break up like the braking bumps on the first corner. A bit flat out building cars at work at the moment but always willing to pop down and give you a hand with some track maintainance for a few hours when I have some spare time
