OZ Racing Ultraleggera Wheels

OZ Racing Ultraleggera — Iconic Italian Six-Spoke Alloy Wheel Since 1990

The OZ Racing Ultraleggera is one of the most iconic and enduring alloy wheel designs ever produced. Introduced in 1990, its name translates from Italian as "ultra-light" — a promise delivered through precision low-pressure casting from high-strength Al Si 7 Mg aluminium alloy, followed by a full T6 heat treatment cycle. The result is a six double-spoke monoblock wheel that has appeared on everything from hot hatches and touring cars to dedicated track-day machines across three decades. Made in Italy, the Ultraleggera combines race-proven heritage with the engineering discipline that defines OZ Racing as a brand.

Available Sizes

• Diameters: 13" | 14" | 15" | 16" | 17" | 18" | 19" | 20" | 21" | 22" | 23" | 24"
• Widths: 5J – 14.5J
• Construction: Monoblock cast alloy (1-piece)
• PCD options: 4x100, 4x108, 5x100, 5x108, 5x112, 5x114.3, 5x120

Recommended fitment notes: The Ultraleggera's size matrix covers the vast majority of European, Japanese, and American sport compact and touring platforms. Check brake calliper clearance before ordering — larger aftermarket kits may require the 17" or 18" options.

Engineering heritage: The Ultraleggera's low-pressure casting process forces molten Al Si 7 Mg alloy into the mould at controlled pressure — producing a denser grain structure and lower porosity than gravity casting. The subsequent T6 heat treatment (solution heat treatment + artificial ageing) raises the yield strength of the alloy to optimise the strength-to-weight ratio. This combination was chosen for the Ultraleggera in 1990 and remains unchanged, as the process continues to meet modern fatigue and impact standards for road and track use.

Finish & Color Options

• Crystal Titanium — OZ Racing's signature bright titanium hue; the original and most recognised Ultraleggera finish
• Matt Race Silver — matte satin silver; low-glare, motorsport-influenced
• Matt Black — matte black; versatile and aggressive
• Race Gold — gloss gold; a classic motorsport reference colour
• Race White — gloss white; clean contrast look
• Matt Bronze — warm matte bronze; popular on slammed and static builds
• Matt Graphite — dark matte graphite; understated and modern

All finishes are applied at OZ Racing's Italian facility to a sealed clear-coat standard. The Crystal Titanium finish features a light machined surface followed by a multi-stage coating process that gives the characteristic sparkle effect under direct light.

Frequently Asked Questions

What is the difference between the OZ Ultraleggera and Ultraleggera HLT?
The standard Ultraleggera uses low-pressure casting combined with T6 heat treatment. The Ultraleggera HLT adds OZ's High Loading Technology (HLT) flow-forming step after casting — this stretches the barrel section, tightening the grain structure and reducing wall thickness while maintaining strength. The HLT is typically 5–8% lighter per size, while keeping the same 6 double-spoke visual identity.

Is the OZ Ultraleggera suitable for track days?
Yes — the Ultraleggera has been used in endurance, time-attack, and club racing applications since the 1990s. It is rated for sustained high-speed use and heat cycling from heavy braking. Always confirm your brake calliper clears the spokes before committing to a specific size.

What tyre sizes fit the OZ Ultraleggera?
Common pairings: 15" × 7J — 195/50 R15 or 205/50 R15; 16" × 7J — 205/45 R16 or 215/45 R16; 17" × 7.5J — 215/40 R17 or 225/40 R17; 18" × 8J — 225/35 R18 or 235/35 R18. Always verify sidewall clearance against your arch and suspension geometry with your actual offset.

Are hub-centric rings required?
The Ultraleggera has a 75 mm centre bore. If your vehicle hub differs — e.g. 72.6 mm for most VW Group cars or 67.1 mm for BMW — hub-centric rings must be fitted. Running without rings on a lug-centric fitment causes vibration and stresses lug hardware. Rings are inexpensive and strongly recommended.

Is the OZ Ultraleggera TPMS-compatible?
Yes — all TPMS sensors that seat on a standard drop-centre rim profile are compatible. The Ultraleggera uses a conventional drop-centre barrel across all sizes. Both screw-in and rubber-valve TPMS types install normally.

Can I use the Ultraleggera in winter with snow tyres?
Technically yes, but OZ recommends a dedicated steel winter wheel set if the car regularly sees road salt and grit. The clear-coat finish provides corrosion resistance, but prolonged salt exposure accelerates surface degradation. If using year-round, clean and re-seal each autumn and spring.

Does the OZ Ultraleggera come with a centre cap?
Yes — a standard OZ Racing branded centre cap is included. Optional carbon fibre centre caps (black or white) and branded lug bolts/nuts are available as accessories.

What is the load rating of the Ultraleggera?
Load rating varies by size — full TUV and JWL compliance data is available in OZ Racing's official technical documentation. The wheel is rated for passenger car road use at all standard load indices. For motorsport applications, confirm maximum load per wheel against your vehicle's weight distribution.

Wheel Care

• Clean with a pH-neutral wheel cleaner and a soft microfibre brush. Avoid alkaline and acid-based cleaners — they can etch the coated finish.
• Rinse with cool water before applying any product, and never spray onto hot brake rotors or hot wheel surfaces.
• Apply a dedicated wheel sealant or ceramic coating every 3–4 months to protect against brake-dust etching and UV exposure.
• Torque wheel bolts to manufacturer specification and re-check after the first 50–100 km of driving following installation.
• Inspect for kerb damage regularly — cast alloy wheels should be checked by a wheel specialist after any significant kerb strike.
