i had them 'slip on spacers' and every time i came back from some dori, my wheel nuts where loose (all of the fronts)
then i decided to take the wheels off n inspect the nuts, the thread were f**ked coz it wasnt loosening off the car, it was being pushed out...
ended up buying $200 worth of wheel nuts/studs.
f**k the slip on shit, get some bolt on spacers they may be around 50-80 each but cant be worse then ur tire flying off mid drift.
