Lot LC51605: 2007 Ferrari 599 GTB Fiorano 6-speed Conversion

The 6-speed manual conversion on the 2007 Ferrari 599 GTB Fiorano, while creating a truly special driving experience, does come with several well-documented challenges:

Main Technical Issues:

1. Flywheel Problems - The converted cars often use a lightweight flywheel that can make the car prone to stalling, especially in stop-and-go traffic. The RPMs drop very quickly between shifts, making smooth driving more difficult than with a factory manual transmission.

2. ECU Coding Headaches - The electronic control unit requires extensive reprogramming to work properly with the manual transmission. The factory ECU calibration for manual cars was reportedly “half-arsed” according to conversion specialists, requiring custom tuning to get the rev-matching and torque delivery right.

3. Parts Availability - Since Ferrari only made a tiny number of factory manual 599s, getting authentic parts for the conversion is challenging and expensive. Many components need to be custom fabricated or sourced from extremely limited suppliers.

4. Cost and Complexity - As you can see from this listing, the conversion alone cost over $104,000 ($84,990 for mechanical work + $19,551 for electronics), making it a very expensive modification that requires specialist knowledge.

The Good News:

• Modern conversion kits from specialists like EAG, SBR Engineering, and Out of the Gate have largely solved many of these issues
• The converted cars reportedly drive better than the few factory manual 599s that exist
• Parts supply is improving as more companies offer conversion components
