Team Saxo (who makes the plastics for the CRC front end) actually made hopup posts for their car that accomplishes this, but there's no Saxo dealer in the US to my knowledge, and $30 shipping for a $4 part is crazy. I'm surprised that CRC hasn't brought these over or made some of their own. Every CRC owner at our track has had the same issue at some point.

Team Saxo steering stops



Here's how I fixed mine. I used some hex-head M3 bolts that fit pefectly into the nut recess in the lower side of the socket, then I screw on some posts that I had 3d printed from the top. You could use regular standoffs that are threaded for 3mm in the same place.
