The only complaint I have heard about that area is the bearings seem to be deteriorating at a rapid rate. If you have extrawide wheels and tires or 2" plus spacers or both, be aware of your wheel bearings. Tim at SDR motorsports said his bearings were shot after one weekend of riding in Glamis. That is just way too quick for me. Others, on the forums have complained about bearing failure or excessive wear as well. I havent checked mine and probably will not until after this next camping trip New Years.
Now I know in decades gone by that wheel bearings on the racers rides were commonly replaced with aftermarket upgrade substitutes. Are there any Wheel Bearing Manu's out there that could come up with a bulletproof set for us? You Vendors in the world of Racing should have at least one or two sources for this kind of thing.
