I don't think anyone has responded to you on this so here goes:

I used the inline axles on the AD "old school" front suspension in 2002 with some success. I was having trouble with the turn-in part on the steering and knew the oval guys used this to provide a more positive turn-in. I was running well with it on green to medium bite tracks, but found it was extremely agressive on heavy bite tracks. I did use a lot of variation with steering expo to adjust to the conditions, but it can be overkill. You should be able to get the offset steering blocks to work adequately on all types of surfaces. Also, the inline steering blocks did add some length to the wheelbase of the car. That could introduce another problem.

Sorry it took so long to respond. Been doing a heavy schedule of RACING (yeah).
