the problem with those type of axels is that you can not shim on the inside of the steering spindle. i have found that reducing the front track just by a little has helped the steering of the car on high bite carpet a whole lot. we have a guy in town that take the stock assoc axels and drills and taps them so i can us a screw on the end and then slot the back side for a flat blade screwdriver to hold the axel. I usually shim inside the steering spindle to get the steering i want and then the outside to just take up the slop.
