Ultimate Guide to Ferrari Titanium Lug Bolts (M14×1.5×75)

For Ferrari owners who demand both performance and perfection, every detail matters—including your lug bolts. The Lug Titanium Lug Bolts offer an ideal combination of weight reduction, aesthetic appeal, and long-term durability. Manufactured from premium aerospace-grade Titanium alloy, they are a direct OEM replacement for Ferrari part 000247702, and are precision-engineered for superior fitment across a wide range of Ferrari models. Whether you're restoring a classic Testarossa or upgrading a modern 488, this guide has you covered.

1. What Makes These Lug Bolts Special

A. Material – 6AL4V Aerospace Titanium

• Grade 5 Titanium (6AL4V) is renowned in aerospace and motorsport engineering for blending lightweight performance, high tensile strength, and exceptional corrosion resistance.

• Compared to steel bolts, these lug bolts weigh nearly 50% less, substantially reducing rotational mass, which improves acceleration, braking, and handling.

• Titanium offers zero corrosion, ensuring longevity even under tough weather conditions and brake heat.

• Rolled threads enhance fatigue resistance and durability.

B. Hand‑Finished Polish

Every bolt is meticulously hand-polished to highlight the silvery brilliance of natural titanium. The finish not only looks stunning against factory wheels but also resists oxidation.

C. PVD Black Option

Our Black Titanium variant is coated via Physical Vapor Deposition, producing a rich, long-lasting finish comparable to the treatments used on premium watches (e.g., Rolex, Panerai). This is not a mere anodization—it's a high-durability coating that stands up to heat, abrasion, and UV exposure.

2. Technical Specifications & Compatibility

These bolts are a direct fit for original Ferrari wheels. If you run aftermarket wheels, verify that the wheel lug bore is large enough to clear the 30 mm flange.

3. Head Style and Length Options

Internal Hex (17 mm)

• Standard 52 mm shaft: Available in 20-piece and 10-piece sets; offered in both Natural and Black finish.

• Extended lengths:

  • 62 mm (+10 mm) – 10-piece sets (Natural and Black)

  • 69 mm (+17 mm) – 10-piece or 20-piece (Natural or Black)

  • 72 mm (+20 mm) – 10-piece (Natural and Black)

Internal hex head bolts use a 17 mm internal hex with a 26 mm head diameter—compatible with OEM tool part 206274.

External Hex (22 mm)

• Standard 52 mm shaft: 20-piece and 10-piece sets; Natural or Black finish.

• Extended lengths:

  • 69 mm (+17 mm) for 15–17 mm spacers: 10-piece

  • 80 mm (+28 mm) for 28 mm spacers: 10-piece

• Special applications:

  • Testarossa: 45 mm shaft – 20-piece (22 mm hex)

  • 308 models: 35 mm and 45 mm shaft sets—10 pcs each.

4. Ferrari Model Compatibility Guide

Modern Ferraris (360 → 812 & More)

All modern Ferrari models that use stock conforming wheels are compatible with the M14×1.5×75 (52 mm shaft) lug bolt variants. Choose style (internal or external hex and finish) based on your tool preference and vehicle aesthetics.

Spacer Application

• 62 mm / 69 mm / 72 mm bolt variants support wheel spacers up to 20 mm.

• Always confirm the thickness of the spacer before ordering.

Ferrari Classics

• Ferrari Testarossa:

  • 22 mm head, 45 mm shaft – OEM-style, 20-piece

• Ferrari 308:

  • Front wheels: 35 mm shaft, 10-piece

  • Rear wheels: 45 mm shaft, 10-piece

• Ferrari 348 (USA ‘94 spec):

  • Rear bolts are 80 mm shaft; choose 80 mm extended version. Older models use 55 mm rear/52 mm front.

5. Benefits for Ferrari Enthusiasts

A. Weight Reduction

Each titanium bolt weighs significantly less than steel—cutting roughly 0.2 to 0.3 lbs per bolt depending on design. Across four wheels, this loss of rotational mass yields quicker throttle response, shorter stop times, and improved cornering.

B. Temperature and Corrosion Resistance

Ferrari wheel hardware is exposed to high braking heat; titanium bolts retain strength and resist oxidation, even after repeated thermal cycles.

C. Improved Durability Over Time

High fatigue resistance and resistance to elemental corrosion mean these lug bolts can last as long as the car—potentially tripling the lifespan of stock hardware.

D. Aesthetic Enhancement

• Natural titanium offers a clean silver finish that contrasts beautifully with dark wheels.

• Black PVD provides deep, stealthy tones while maintaining shine.

• Complementary internal hex or external hex allows you to match tool use and wheel design.

6. Installation & Torque Guidelines

To ensure safe performance:

1. Clean wheel studs and bolt threads thoroughly.

2. Optional: Apply a light, high-temperature anti-seize compound to prevent galling.

3. Using a torque wrench, tighten bolts in a star pattern to:

   • 130–150 Nm (95–110 lb-ft) for M14 turning bolts

4. Re-torque after initial 50–100 km of driving.

5. Avoid using impact wrenches during final installation.

6. Confirm correct seat type—these bolts use a conical seating; don’t install on flat- or contour-seat wheels.

7. How to Choose the Right Bolt

8. Frequently Asked Questions

Are these compatible with aftermarket Ferrari wheels?
Only if the wheel’s bore allows for the 30 mm flange. Always check with the manufacturer before installing.

Should I choose internal or external hex head?
Internal hex heads provide clean visual lines; external hex head (22 mm) accommodates standard sockets.

What makes Black PVD superior to anodizing?
PVD delivers a stronger, more durable finish that resists chips, scratches, and UV exposure better than anodized or powder-coated finishes.

Can I use my OEM torque settings?
Yes, use Ferrari's factory torque settings (130–150 Nm) with a torque wrench—avoid power tools.

Do I need re-torque?
Yes—re-torque after your first drive to ensure consistent clamping force.

9. Why These Lug Bolts Offer Real Value

• OEM fit and finish equal to or better than dealer-installed hardware.

• Long-term durability far beyond standard steel lug bolts.

• Weight savings that contribute directly to driving performance.

• Aesthetic customization, from polished silver to stealth black.

• Cost-effective: a full set offers substantial savings over dealer replacements.
