I have a set of them for my RS4 18SS. You need to be fairly agressive on the gas to get them to drift but it works good. After about 3 hrs of drifting, they have lost their thread now. I guess another 2 hrs and I will need to change them.
I also made a few sets of ABS tires. ABS is very slippery and works great on my electric, not quite enought traction for the high power Nitro.
