As a rule of thumb, a 1″ spacer is approximate -25mm offset. This is because wheel spacers essentially reduce the distance from the wheel center to the hub assembly, they subtract the offset. Giving an example, if you get a +45mm offset rim, then a 1″ spacer changes the offset to be +20mm (45mm – 25mm = 20mm). People care about giving their vehicles the right stance. The lower the offset, your wheel will sit further away from the suspension, which is a tough and aggressive look for some drivers.

Besides wanting a better appearance, people want their cars to perform better too. If you add a 1″ spacer on each wheel, then the track width will increase by about 2 inches. For many, this means giving the car more stability and grip which is good for cornering. Reducing 1-inch wheel offset also means increasing 25mm backspacing. This is helpful in clearing big brake clearance issues. Larger brakes are safely installed, which improves the performance even more.

Is Using 1″ Spacer to Reduce Offset A Good Idea?

Depending on how you drive your vehicle or want to drive it rather, a 1″ wheel spacers may be a perfect selection. To prevent your tires from rubbing the fenders, your wheels have to have the right offset. There are wheels designed for street racing or off-roading. And different wheels are made with different offsets. Arguably, the OEM wheel offset is the right offset for tires. But slight changes can be made.

If you get aftermarket or second-hand wheels, always measure the offset first. When your wheel mounting surface is closer to the outside or road side of the vehicle, this is a positive offset. Too much positive offset would pull the wheels in closer to the vehicle. With the help of wheel spacers, you won’t necessarily have to get a set of new wheels with the right offset. This could save much budget as well as time for you.
