Hubcentric Wheel Spacer Kit for Maserati Ghibli Quattroporte GranTurismo (2016-2024) 15mm

Precision-Machined 15mm Hubcentric Wheel Spacer Kit for 2016-2024 Maserati Ghibli, Quattroporte, GranTurismo (M156 / M157 / M145)

What it Does: The 15mm Hubcentric Wheel Spacer Kit widens the factory track width on 2016-2024 Maserati vehicles to improve lateral stability, eliminate sunken wheel fitment, and clear upgraded braking components.

The Stock Maserati Ghibli, Quattroporte, GranTurismo Track Width Limitation

From the factory, the M157 Ghibli, M156 Quattroporte, and M145 GranTurismo platforms feature conservative wheel offsets that recess the tire profile deep inside the wheel arches. This inset track narrows the roll center geometry, reducing cornering turn-in response under high-G loads. Additionally, non-hubcentric or generic slip-on spacers lack the proper center-bore register, creating excessive shear loads across the wheel studs and inducing high-speed rotational vibration throughout the suspension assembly.

The Engineering Solution

Manufactured from forged 7075-T6 aluminum alloy, this 15mm kit delivers high tensile strength and thermal stability without adding excessive unsprung rotational mass. Precision-engineered with an integrated hub-centric collar matching the factory 67.1mm center bore, it transfers radial vehicle weight directly to the wheel bearing hub rather than the fasteners. Supplied extended-shank high-tensile alloy wheel bolts preserve full thread engagement into the hub assembly to withstand high lateral torque demands.

What's Included

• Hubcentric 15mm wheel spacers

Frequently Asked Questions & Fitment Warnings

Does this fit the M157 Ghibli, Quattroporte, and GranTurismo?

Yes, this is a direct fit for the 2016-2024 Maserati Ghibli, Quattroporte, and GranTurismo equipped with F160, F154, or F136 powertrains; always verify clearance and lug seat configuration prior to final torque sequence.

What torque specifications should be used during installation?

Torque the extended fasteners in a star pattern to the factory Maserati specification of 118–125 lb-ft (160–170 Nm), re-checking torque after the initial 50–100 road miles.

The Maserati Precision Standard

Engineered for high-performance Italian touring platforms, this spacer system delivers zero-vibration hub engagement and uncompromising high-speed mechanical compliance without triggering stability control or suspension faults.
