FERRARI 488 GTB F142M 20 wheel set

In 2026, the market for 20-inch wheels for the Ferrari 488 GTB (Internal code F142M) offers a wide range of options, from factory “Genuine” replacements to high-performance forged aftermarket sets.

1. Technical Specifications

The 488 GTB uses a staggered setup. To maintain the car’s handling and electronic stability control (ESC) calibration, you must stick closely to these factory specs:

• Front: $20 \times 9\text{J}$ ($+44\text{mm}$ offset)

• Rear: $20 \times 11\text{J}$ ($+38\text{mm}$ offset)

• Bolt Pattern: $5 \times 114.3\text{mm}$ (Note: Some earlier Ferraris used $5 \times 108\text{mm}$, but the 458/488/F8 platform uses the $114.3$ standard).

• Center Bore: $67.1\text{mm}$.

• Tires: Usually paired with $245/35\text{ R20}$ (Front) and $305/30\text{ R20}$ (Rear).

3. Key Part Numbers (OEM)

If you are sourcing individual replacements, watch for these common part numbers:

• Front ($20 \times 9$): 318889 (Standard), 315893 (Diamond Cut Forged), 310139 (Corsa Grey Forged).

• Rear ($20 \times 11$): 318890 (Standard), 315889 (Diamond Cut Forged), 308764 (Corsa Grey Forged).

4. 2026 Purchase Considerations

• The “Pista” Look: Many owners in 2026 are retrofitting 488 Pista wheels (Part #342191) onto the GTB. While they fit, they are significantly lighter and more fragile; ensure you aren’t buying “replica” Pista wheels, which are common and much heavier.

• Hardware Compatibility: OEM Ferrari bolts are typically longer than aftermarket ones. If you switch to an aftermarket brand like Apex or Vossen, you will likely need to buy a specific lug bolt kit (approx. $500 – $600) to ensure proper thread engagement.

• TPMS Sensors: When buying a “wheel set,” check if the TPMS (Tyre Pressure Monitoring System) sensors are included. A new set of four genuine Ferrari sensors (Part #314821) will add roughly $700 – $800 to your total.

5. Visual Identification

• Standard Wheels: Usually a simple 5-spoke design in painted silver.

• Forged Wheels: Often have thinner spokes and “FORGED” stamped into the rim or back of the hub.

• Diamond Cut: Features a two-tone look with a polished aluminum face and darker grey/black “pockets.”
