No problems here. I usually wash my car, pull it in the garage to dry it, and leave it parked for at least a day or 2 before I drive anywhere since it's not a daily.
I park it in first gear with the e-brake engaged all the time.
@ColonelAdama Awesome thread! Its making me want to convert to JB4 but idk if I have the time and patience to dial in my MT. I know I'll have similar problems as you with the Kenji DP...
