Frequently Asked Questions
What is the Sparco 015R330PSO?
The 015R330PSO is the Sparco R330B steering wheel in black suede with integrated IP68-rated push buttons, a 330mm diameter, and a flat dish design intended for competition and high-performance street use.
Does the R330B come with a horn button?
No. The R330B is not supplied with a horn button. If a horn is required, a separate horn button kit compatible with 3-spoke Sparco wheels must be sourced.
Is a hub adapter included?
No. A vehicle-specific hub adapter (boss kit) is required for installation and is sold separately. The 6-bolt 70mm PCD mounting is compatible with hubs from Sparco, OMP, Momo, and other popular brands.
What are the push buttons used for?
The two IP68-rated buttons are wired separately with separate connectors; typical applications include push-to-talk radios, launch control activation, or any low-current vehicle trigger function (max 200mA / 50VDC).
Is suede more durable than leather for a steering wheel?
Suede provides a higher-friction grip surface that resists slipping, especially with gloves. It requires periodic cleaning to maintain appearance but is preferred in competition environments for consistent tactile feedback.
What vehicles does the R330B fit?
With the appropriate hub adapter, the R330B fits virtually any vehicle. It is a universal competition steering wheel and is not vehicle-specific.
Will this pass FIA or MSA technical inspection?
The Sparco R330B is designed for competition use; however, customers should confirm with their sanctioning body whether a specific FIA homologation is required for their class, as regulations vary.
What is the difference between the R330 and R330B?
The R330B adds two integrated IP68-rated push buttons to the standard R330 design, making it suited for applications where additional driver-operated switches are needed without a separate switch panel.

Steering Wheels & Hubs
Steering wheels and hub adapter kits allow drivers to install aftermarket sport or racing steering wheels on factory steering columns without modification. Hub adapters are vehicle-specific components that match the factory column spline to the industry-standard 6-bolt aftermarket steering wheel mounting pattern. Popular Steering Wheel and Hub Combinations Popular combinations include compact sport steering wheels paired with vehicle-specific hub adapters, flat-bottom steering wheels with quick-release boss kits for track vehicles, and full racing wheel and hub adapter packages. Many hub adapters are available with integrated quick-release mechanisms that allow the steering wheel to be removed for security or to allow easier entry and exit in tight cockpits. How do I choose the right hub adapter? Hub adapters are vehicle-specific and must be matched to the year, make, and model of your vehicle's steering column. The adapter bridges the factory column spline pattern to the 6-bolt mou...
