I run fubar lockouts on my Hot axles. I'd definatly go the JP route if I had berg's. Nothing against fubar. They are great and do what they are suppose to. I really prefer the look of the JP lockouts.
I got a Fubar crawler stand from John too.
My Mayhem 7's with Rover's. Before I sold the wheels.
I orders this morning so im hoping today . Joe bruiser on rctech sugessted the panthers with the soft white foam & not the memory foam. Ha also sugessted the fubar lock over the jpcustoms . He said there is less chance of snagging . The 4.0 looks great .
