I did this to mine a while back. It's rather simply, take a xacto to the foam, trim it away. Next pull out some electrical tape or something close to it and start wrapping away. May take about a good 20+ times around the wheel. Build it up thick. Next, grab your wheel and test install. If loose, wrap some more. If tight, pull back some of the tape. It should be a rather tight fit. You don't want it to fall off during the race. If you do it correctly, the wheel should stay nice and snug on the steering wheel. If done incorrectly you'll notice some slop and looseness on the wheel. Hope that helps. Good luck!
