+1 build it right the first time with the high quality components and break it in properly and it will last a long time. Mine is 2 months old and still feels like new. Racing 1-2 times a week and a practice session.
Also I have panthers in my sc and they were complete garbage untill I wore of 60% if the tread. Now they are just subpar...
Never buying them again but the foams are really nice.
