Yes, I am running the 3Racing chubs. They are only like... less than $12 a pair from RCMarket. You have to shim differently above the spindle. I think I am using a 1mm shim. They are maybe alittle more sloppy than the stock ones. The carbon ones just break to damn easy. Even a simple side slap from another car seems to crack them. That's why I switched. I'll post a pic soon.
