I have a Rear Locked Diff on my TT-01 and Love PVC.. Its Great on Concrete and smooth Asphault...Its Great for Technical Drift as You dont Need speed.. Just need to Practice control..

I wont Change from PVC, I also Use Drift Rubbers but they make the Car Bounce when Cornering, Good for Ultra Smooth Surfaces but the Slip to grip ratio of PVC is Just cooll.. Who Cares if it is White... Its Cheap and Gets you sliding..
