The REFERENCE torque spec for the 2007-2025 Maserati Granturismo wheel bolts will be 140 Nm (just for REFERENCE, please inquire with a tire expert). As long as you properly torque them, genuine brand wheel bolts won’t come loose easily. Set the torque wrench to the manufacturer’s recommended value. Then simply turn the wrench handle until it reaches the torque mark. Then, tighten the wheel bolts a quarter turn at a time following the crisscross sequence (in a “star” pattern).
If you add wheel spacers, longer Maserati Granturismo wheel bolts are a must option. Tire engineers explain that only if the bolt thread is long enough can the bolts provide proper clamping force to keep these Maserati wheel spacers and wheels balanced. It is highly recommended to ensure a minimum of 6 – 8 complete threads of engagement for the lug nuts. For an M14 wheel bolt, you would need at least 14mm threads to ensure a safe engagement.
Can Aftermarket Maserati Granturismo Wheel Bolts Break?
Unlike most lug bolts people find in the market, BONOSS forged ISO grade 12.9 Maserati Granturismo wheel bolts are exceptionally strong, making them very durable. Due to the super forging process, BONOSS forged Maserati wheel bolts won’t break easily. They are ISO grade 12.9 approved. tensile strength≥ 1,282 MPa, limited life range test ≥ 2,000,000 stress cycles without damage, ultimate tensile load≥ 152,000 N, hardness (HV) ≥ 395, NSS ≥ 192H.
When torqued correctly, BONOSS forged ISO grade 12.9 Maserati Granturismo wheel bolts can maintain high clamping force even under extreme operating conditions. The increased performance ensures safety on the road even when you accidentally come across an obstacle. Particularly, BONOSS forged extended Maserati GT wheel lug bolts give neutral salt spray resistances exceeding 192 hours. That is why sometimes aftermarket wheel bolts are even safer than the OEM ones.
