The Maserati Granturismo wheel spacers provide many benefits. By adding the proper amount of extra space between the rim and the hub assembly, the wheels will stick out to flush the fenders, giving your vehicle a more sporty and fiercer look. This also increases the track width, hence reduce body roll and enhance the ride quality.

The most ingenious thing about Maserati Granturismo wheel spacers is that they allow you to safely fit wider tires on your existing rims or upgrade to bigger brakes without rubbing issues. In general, most Granturismo owners opt for spacers between 11mm to 30mm in thickness. In this guide, we’ll delve into the ideal thickness for your Granturismo, and the best spacer brand.

Best Maserati Granturismo Wheel Spacers Size Chart

Choosing the best Maserati Granturismo wheel spacer size depends on your personal preferences and car’s modification. Here are a few tips to help you decide:

Wheel Offset:
The Maserati Granturismo wheel spacers reduce the wheel offset. Lower offsets make the wheels sit further out. For example, the stock offset is +50mm, then a +60mm offset wheel will sit further inside the wheel well. In this case, you can use 11mm wheel spacers to make the offset +49mm (60-11=49mm).

Tire Width:
Wider tires can fill the wheel well more, so you may only need a thinner spacer (11mm to 15mm) if you plan to use wider tires. On the other hand, narrow tires may require larger spacers (20mm to 25mm) to achieve a flush look.

Extra Modifications:
If you added a wide-boy kit with stock wheels and tires, you would need Maserati Granturismo 50mm wheel spacers to avoid rubbing issues. If you just need a little bit of wheel clearance to clear bigger brake calipers, then 3mm to 11mm spacers are sufficient.

Bolt Pattern (PCD):
Wheel lug pattern is one of the most important factors in identifying wheel dimensions. Double-check the vehicle bolt pattern in your owner’s manual before buying a set. For example,

  • 2023-2026 Granturismo II (M189): PCD=5x110mm, CB=65.1mm, Thread=M14x1.5mm.
  • 2007-2019 Granturismo I (M145): PCD=5×114.3mm, CB=67.1mm, Thread=M14x1.5mm.

Who Makes the Best Maserati Granturismo Wheel Spacers?

When selecting the best wheel spacers for Maserati Granturismo, BONOSS excels in safety and performance. With the advanced technology and unmatched quality, BONOSS offers several key advantages that make their spacers a top choice.

1. Useful Active Cooling Function

With the same price as most rim spacers, BONOSS forged active cooling Maserati Granturismo wheel spacers provide an active cooling function. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.

The air takes away the heat to actively dissipate heat for the brakes. Such BONOSS forged active cooling wheel spacers for Maserati Granturismo improve the cooling efficiency, reducing brake thermal decay, and improving road safety.

2. Aerospace-grade Aluminum Materials

All BONOSS forged active cooling Maserati Granturismo hub-centric wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (as strong as aviation aircraft). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.

3. Full-cone Seat with Zero Loosen

Full-cone seat design provides a larger contact area, more force acreage, and better fitting. This allows the studs and nuts to apply enough clamping force to lock the BONOSS forged active cooling Maserati Granturismo aluminum spacers. In that case, the hub-spacer-wheel connection can be fastened firmly, meaning no vibration.
