The bolt pattern of a 2012-2024 Subaru BRZ spacer is 5x100mm. In the automotive world, BRZ wheel spacers can be as thin as 8mm or as thick as 70mm. How big wheel spacers fit your vehicle is often determined by how much wheel gap you have. Since the fenders are very important parts that prevent the rolling mud or debris from hitting anyone or anything, it is not recommended to use BRZ wheel spacers to stick your tires out past the fenders.

Sometimes, you get a set of second-hand wheels, apart from the bolt pattern issues, you may face an offset problem. Fortunately, the BRZ 5×100 wheel adapters can fix the wrong bolt pattern and offset. For example, if you want to install 5×114.3 wheels on a BRZ, 5×114.3 to 5×100 bolt pattern adapters will be the solution. By pushing the wheels out, they reduce the offset. Simply put, a BRZ 25mm wheel spacer will reduce the 25mm offset, and the wheel will be pushed out about 25mm.

Who Makes the Best BRZ Spacers?

Some of the benefits of adding BRZ wheel spacers are improved handling, better stability, more space for wider tires, larger-sized rims, and bigger brake calipers. As mentioned before, they provide a wider stance for your car. Aside from the above functions, BONOSS forged active cooling BRZ spacers provide more additional advantages. For example, the active cooling technique. Distributed in petal shape, the cooling grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.

The flowing air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system. In addition, the side knurling design eliminates internal stress and enlarges the cooling area which is good for the active cooling effect. This boosts the heat dissipation efficiency of the rotors, reducing brake thermal decay, hence improving road safety. With the same price as many quality spacers, BONOSS forged active cooling BRZ spacers are more advantageous.

How Do I Know What BRZ Spacers Are Good?

If you get bolt-on BRZ spacers, please check the wheel studs and lug nuts. The biggest reason you need BRZ spacers with high-quality hardware is to ensure driver safety. Most OEM Subaru studs are ISO grade 10.9 standard. Undoubtedly you need at least ISO grade 10.9 or higher wheel studs to avoid breaking. BONOSS forged active cooling BRZ spacers come with ISO grade 12.9 wheel studs and ISO grade 10 wheel nuts to ensure a strong wheel-spacer-hub connection.

The provided wheel studs have achieved ISO standard grade 12.9, tensile strength≥ 1,220 MPa, ultimate tensile load ≥ 152,000 N, hardness (HV) ≥ 395, and NSS ≥ 500H. Additionally, BONOSS forged active cooling BRZ spacers come with full-cone lug seats. Full-cone seat design allows the studs and nuts to apply enough clamping force to lock the BRZ spacers, avoiding any potential loosening risks. In that case, the axle-spacer-wheel connection can be fastened firmly, meaning no vibration, fewer stress loads, higher safety, and a longer service life range.
