I guess your running the plastic front carriers. Get the PE ones, ben rockin mine for well over a year and they're still doing well other than typical bearing wear.
The guys I run SCT with are a rough driving bunch and if I haven't broken one yet they are plenty tough. Lots of carnage when we all get together on the track, 5-6 SCT's and goofy rednecks driving them. It's quit the site
I retired from RC, now life is all about guns and long range shooting.
