The first thing to check are:

How to fit a non airbag steering wheel

Filed under: Steering — Jeff 993TT @ 3:07 pm

This is a DYI overview for the guys that asked me to post how to change you airbag steering wheel to a racing, non airbag wheel. I have a great factory carbon fiber wheel that was too nice for the track and got a little slippery even with gloves. I decided, since the car spends most of its time on the track, to get a smaller 3-spoke wheel. I got the Momo GT3R wheel, (very similar to the Momo Mod 7 wheel) with Porsche stamped into one of the spokes and the Porsche crest horn button. I am using the Momo 7004 hub adapter. There is a DYI on www.p-car.com on how to take your wheel off so I won

The 3 spoke 996 steering wheel can be fitted to the 993 without modification. This modification takes approximately 1/2 an hour. Air bag function and horn functions are retained.

The cost of a 996 steering wheel varies from about $700-$1200, depending on color, options, and whether the air bag module is included. The existing air bag module from the 993 cannot be used on the 996 steering wheel.

Following are the part numbers and Porsche suggested list prices.

996 803 089 04 – $280.59

Air bag Tepquipment

The air bag is considered a hazardous material and can only be shipped via ground.

Be sure to disconnect your battery before disconnecting the existing air bag or you will trigger a fault code in the computer.
