Oookay. Well, you're welcome to your opinion. However, general consensus is that the Yok tires are better for any type of drifting whether it be angle or distance. But, to each his own. However, the GD series are on concrete and they all use Yok tires. In my personal experience, Yok work best for anything. I haven't tried the HPI drift spec tires yet so I won't comment on those. But between yok and homemade, Yok work better for me. That being said, I haven't used Yok tires in almost 7 months cuz they're expensive and on the surfaces I drift on, they'd wear out to quickly. I will probably pull them out for video shoot purposes because they allow much more stability and control and want a video to look a certain way. However, for my every day drifting, I also use ABS pipe.
