Anyone use the TKR5199B HRC Rear Hub Set? Are the optional hubs worth it and do they work with the universal driveshafts?

From Tekno:
"The Tekno HRC Rear Hub Set allows you to lower the hinge pin position compared to the stock rear hubs (TKR5199). This raises the rear roll center to provide increased on power traction and stability while decreasing body roll, and these gains also come with improved rotation into a corner and no compromise in on-power steering. To reduce wear and increase part lifespan, they are molded from durable nylon and include locations for hinge pin set screws."
