I have had my dust caps nicked twice in 1 month!!!! They were nothing to fancy, just chrome hexagen style ones. They only stole passenger rear on 2 occasions!!! I am sick of it now so just stuck sh*tty black plastic ones back on it I know you can get locking ones but i would rather not have some little scrout ragging f*ck out of my valve and maybe get to annoid and kick the car or something. I have seen some right fancy dust caps on some cars, gold crowns, dice, skulls, 8 balls etc so god knows how annoid they must feel when theres go missing!!! Who else have had theres stolen and how often??
