Bernard- Those are the recalled magnesium wheels and I would not recommend them unless you had hardened inserts made and installed for the bolt holes. That is where the wheels were cracking and why Ferrari recalled them.

From the rear, it is easy to tell the difference between the recalled magnesium wheels and the new aluminum wheels. The mag wheels have D section, solid spokes and the new wheels have a C section, hollowed spoke. These two photos plainly show the difference.

1999 Ferrari 550 Maranello Wheels Recall 01V297000

NHTSA: Action Number: N/A Service Bulletin Number: 01V297000

• Report Date:
  Sep 24, 2001
• Component:
  Wheels
• Potential Units Affected:
  468
• Manufacturer:
  Ferrari North America

Summary: Vehicle description: passenger vehicles. The wheel bolt inserts fitted in the magnesium wheel can show signs of cracking.

Consequence: If the wheel bolt inserts begin to crack, a reduction of the torque applied to the wheel would result. Vehicle handling could be affected, increasing the risk of a crash.

Remedy: Dealers will replace all four magnesium wheels with wheels made of aluminum, which are not fitted with inserts. All the wheel bolts will also be replaced because the aluminum wheels require a different type of bolt. Owner notification began october 1, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact ferrari at 1-201-816-2651.

Notes: Also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
