Are wheel adapters / spacers safe?
When used in the right manner, wheel spacers are safe. It's a good cost-effective way to widen your vehicle's wheels for handling and cosmetic purposes.
Now, you may think that all spacers are made the same but they aren't. There are the universal ones you see from wheel and tire shops which are spec'd to fit all manner of vehicles and wheel patterns. These are cheaper and are usually available only up to a certain thickness. Be aware and don't make the common mistake of putting more than one of these types of spacers per wheel. There's a risk of causing imbalance to that wheel.
Another commonly seen wheel spacer is made to be hub-centric (meaning it will fit and center exactly onto your existing hubs), and more often than not, it's vehicle application specific, apart from coming in many thicknesses. It does cost more but is worth the extra cost. It usually also comes with new bolts or wheel studs of the proper length to ensure a proper and safe fit.
Whats the purpose of a wheel spacer?
Appearance: You want to push the wheels out for a better stance and more aggressive look. This is totally subjective to your personal tastes.
Clearance: Many wheels are not compatible with big brake kits. The spoke of the wheel will scrape the new brake caliper and you need a wheel spacer to push the wheel spoke away from the caliper.
Correction: You may have bought a set of wheels that don't have the correct offset for your car. The offset may be too high, resulting in the wheels sitting too far inward. This may cause the tire to now rub on the inside wheel well, or on suspension components, etc. A wheel spacer will push the wheel out and 'correct' the offset.
Handling: By spacing the wheels further apart, you can make the car more stable and corner better. You can gain a similar effect as adding a wider wheel without the added weight and expense.
Will wheel spacers / adapters cause my wheel studs to bend/break?
No. The load from a wheel is transferred to the axle/hub through the friction of the clamped joint, not through the wheel stud. A wheel stud can only bend if the lug nuts are not properly torqued, in which case the wheel is about to fall off due to poor/improper installation.
