For me I had the caps lyin around and I don't use a fan for I only run 13.5's and the speedo does not even get warm. If I were running the XBR in a sedan I may think about getting a fan, but no need for the dirt cars at all. If he is only going to run 13.5 and 10.5 he has nothing to worry about and does not need the GTB. The guys I run with have GTB's and Sphere's and I don't feel I am giving anything up to them at all. If he decides he wants to run something faster then an 8.5 he can upgrade later. The XBR has lipo cut off as well.
