man i have popped a bunch but mostly thats my fault. my stock veh i havent been havin the issue as much but i def ran into the same thing with the back ones folding/shearing after time.I just built my mod and have made a few mistakes in itside note-i saw a guy running the round grey losi ballcups on his b4.1 this weekend. I dont think the stock ball cups are too weak as i have snapped some ballstuds in half and i would rather pop a ballcup then replace u braces or whatever the snapped ballstud is in, i havent had any pop off un warranted so ill just try and clean up my mod driving..
