I was thinking what brand also? I've never run studs on this thing. Used to have a 1.4 cat track on it now this cobra which is new. The Cobra seems to hook up ok but I'm not much of a racer so I really don't care if it spins some......or alot...lol
Im not a fan of dual runners, my 2000 wouldnt steer for crap with them. My friend has a 04 sabercat 500 that he bought last year. He bought new single carbides for it as it was not stteering well at all. When we replaced them we were surprised that It had daul runners also...went right in the trash and sled handles great.
As for the rear getting loose,it all dependson snow conditions really.
