Simagic P-325D steering wheel 325 mm, leather rim, for direct-drive systems, without hub

The Simagic P-325D is a 325 mm steering wheel rim designed for use with direct-drive sim racing systems. Constructed with a leather-covered grip and a compact diameter, the P-325D provides a familiar road and GT-style feel for drivers seeking improved hand positioning and tactile feedback. The wheel is sold without a hub, allowing compatibility with a range of quick-release hubs and mounting plates used in sim racing cockpits.

Advantages

The leather rim offers a secure, non-slip surface that enhances control during aggressive inputs and long sessions. The 325 mm diameter balances precision and agility, suitable for both road and GT-style setups. Designed specifically for direct-drive systems, the rim maintains close contact with force feedback effects delivered through compatible hubs and bases. The absence of a built-in hub makes the rim lightweight and adaptable to multiple hub interfaces.

Suitable for

• Sim racers upgrading from larger or stock rims to a compact leather rim for better control
• GT and road racing setups where realistic hand positioning is preferred
• Users building or customizing a sim cockpit with a compatible quick-release hub
• Drivers who prioritize tactile grip and long-session comfort

Key specifications

• Rim diameter: 325 mm
• Rim cover: leather
• Compatibility: designed for direct-drive wheelbases via compatible quick-release hubs or mounting plates
• Construction: lightweight rim without integrated hub
• Intended use: road and GT-style sim racing

How to use

Attach the P-325D rim to a compatible quick-release hub or mounting plate according to the hub manufacturer's instructions. Ensure the hub and wheelbase are powered off while mounting to avoid accidental inputs. After mechanical installation, verify proper alignment and tightness of fasteners, then power on the wheelbase and check that force feedback and rotation limits function as expected. Adjust your sim software steering rotation and deadzone settings to match the new rim diameter for consistent steering feel.

Recommendations

Clean the leather surface occasionally with a damp cloth and mild leather cleaner to preserve grip and appearance. Avoid exposing the rim to prolonged direct sunlight or extreme humidity. Use compatible quick-release hubs specifically rated for direct-drive torque to ensure secure mounting and reliable force feedback transmission.
