Sparco Steering Wheel Hub Mitsu Evo 8/9 (Center Nut Style ONLY - Will Not Work w/Pinch Bolt Style)

Bolt a 6-Bolt Sparco Steering Wheel to Your 2003-2006 Mitsubishi Lancer Evolution 8 or 9 Center-Nut Column

The Sparco 01502103CA is a steering wheel hub adapter that allows fitment of any 6-bolt Sparco steering wheel to the 2003-2006 Mitsubishi Lancer Evolution 8 and Evolution 9 equipped with the center-nut style steering column. The Evo 8 and Evo 9 were produced with two different column designs: a center-nut style and a pinch-bolt style. The Sparco 01502103CA is compatible with the center-nut column only and will not work on the pinch-bolt column variant. Verify your column style before ordering by removing the airbag cover and inspecting the steering shaft end. If you have a pinch-bolt style column, a different hub such as the Works Bell unit is required. The 01502103CA is manufactured in Italy by Sparco to OEM-level tolerances and provides a secure, direct-bolt interface between the Sparco 6-bolt pattern and the vehicle's steering shaft.

Frequently Asked Questions

Remove the airbag horn pad from the center of your stock steering wheel to expose the steering column end. A center-nut column will show a single large nut at the center of the splined shaft. A pinch-bolt column will show a bolt running perpendicular through a collar that clamps onto the shaft. The Sparco 01502103CA is compatible with center-nut columns only. If you have the pinch-bolt style, the Works Bell hub for Evo 7/8/9 is the correct alternative.

Yes. The Sparco 01502103CA uses the standard 6x70mm PCD bolt pattern that is shared by most European and Japanese performance steering wheel manufacturers including Momo, OMP, NRG, and others that use the 6-bolt 70mm standard. Verify that your steering wheel uses a 6x70mm PCD before purchasing.

Yes. Installing any aftermarket steering wheel hub adapter replaces the OEM steering wheel and deactivates the driver-side airbag. This is typically done for track, race, or time attack applications where the OEM wheel and airbag assembly are removed. Do not install this hub adapter on a street vehicle that requires a functional SRS airbag system. A clock spring or SRS resistor may be required to prevent airbag warning lights if the vehicle is driven on public roads.

Yes. Sparco lists the 01502103CA as fitting the Mitsubishi Evolution 7, 8, and 9 (all CT9A chassis variants) that have the center-nut column style. The center-nut column was used across all three generations, though some vehicles in this range also received the pinch-bolt design. Verify your specific column style regardless of model year.

Yes. The Sparco 01502103CA is also listed as compatible with the Mitsubishi Colt (2004 to 2008), which shares the same steering column specification as the Evo 8 and Evo 9 center-nut application. This applies to the Colt sold in markets where that model was available.

No. The 01502103CA is a fixed hub adapter without a quick-release mechanism. It provides a permanent, bolted connection between the steering shaft and the steering wheel. For a removable steering wheel setup, a separate Sparco or aftermarket quick-release unit must be added between the hub and the steering wheel.

The Sparco 01502103CA hub adapter accepts the 6x70mm bolt pattern used on all Sparco 6-bolt steering wheels. This is the standard hub pattern used across most of Sparco's performance and competition steering wheel lineup. Wheels with a 3-bolt or non-standard pattern are not compatible.

No, when properly installed and torqued. The 01502103CA is precision-machined to fit the Evo 8/9 center-nut shaft without slop. Ensure the center nut is torqued to the specification in Sparco's instructions and that the steering wheel bolts are torqued evenly. Any perceived looseness post-installation typically indicates an under-torqued center nut or a worn original steering shaft spline.

Installation Instructions

1. Disconnect the negative battery terminal and wait a minimum of 15 minutes to allow the SRS system capacitor to discharge before touching any airbag components.
2. Locate and remove the airbag assembly from the center of the OEM steering wheel per your Evo service manual procedure. Carefully disconnect the airbag electrical connector and horn connector.
3. Using a steering wheel puller tool, remove the OEM steering wheel from the steering shaft. Do not hammer the shaft or wheel.
4. Confirm the column style: check for a single center nut on the splined shaft. If a pinch bolt is present, stop and source the correct hub for your application.
5. Install the Sparco 01502103CA onto the steering shaft, aligning the splines. Thread the center nut on and torque to the specification provided in Sparco's documentation, typically 30 to 35 ft-lbs.
6. Mount the new Sparco steering wheel onto the hub adapter using the 6 provided bolts. Torque evenly in a star pattern to approximately 20 ft-lbs or per Sparco's specification.
7. Install an SRS resistor or clock spring bypass if the vehicle will be operated on public roads, to prevent warning lights and faults.
8. Reconnect the negative battery terminal after all connections are secured and the installation is complete.
