When modifying your car, it's common to use wheel spacers. If you are using slip-on spacers, it is recommended to change your studs to accommodate for the loss of thread on the standard studs. Wheel studs are an important part of your car, don't overlook the fact that even a 5mm slip-on spacer can still create excess stress on your studs. Not only are you reducing excess stress, but you are also ensuring there is a safe amount of thread on your wheel nut. Safety is important and ensuring your wheel nuts are engaged correctly is everything!
