GT40R or GT4088 kit

rx7store.net offers a gt40r kit and a gt4088 kit. I was wondering if anyone had either of these and if people know the goods and bads of each kit.
Thanks

R is ball bearing and the other is not. Ball bearing will boost and respond quicker but is more expensive. https://www.rx7club.com/forum/forumdisplay.php?f=23

I dont think this is gonna cut it on a 2rotor to beat that 900HP S-10 if he can launch/control it.
