lynx , i got my hyper 7 from Angel, it was his personal car that he got that paul coleman used to race himself before angel used it. it is set up with c hubs, i aksed him why not PBS and well they replied that for racing that the c hub preformed better to them. so go figure ....

i personally do not notice a huge difference myself as i am no expert and do not have 2 exact cars side by side except for the hubs to compare.
