i was getting the 7.4x8.25 from sig but they have ran out their stock. so i got some of the other 7.4x8.1 (thin hub) they work fine i flew 4 times balls to the wall and they held togather.. they do seem to be a lil slower.. but that could be on my part with the new header and 8.5 pipe.. i might need to richen or lean her out a bit more...

thanks FF
