I also took a small slice off the steeringblocks underside. So I'm still able to run the steeringblock in it's lowest position.
I don't like the std. Ackerman anyway , so I really didn't bother with it that much.

With inlines shimmed forward I just use the rear hole of the steeringrack and if I use traling with a cut casterblock I use the front hole in the steeringrack. But I'm on inlines shimmed forward about 96.8% of the time.

But to keep the same mechanical Ackerman. You can flip the steeringrack and cut-off the (now) front hole, since it will be rubbing the bulkhead badly. This way you can test and see if you like this setup.
But if you like it, I would strongly advise to make an alu. steeringrack plate. Since it takes a lot of material way of the rack. But its something I've not tried, but its a viable solution.
If your just trying to keep the same "feel" I just would re-adjust your Expo on your transmitter.

On it rubbing shocks, it should be close. But if its really rubbing, you could move the shocktower forward by putting 2 ~ 3 mm shims between the shocktower and bulkhead.
I always use this, but I do it to keep the shocks in the same angle as the arms.
When you keep having problems rubbing your just triing to get some extra steeringlock out of the car . Just shave a bit off the shock location in the arm, so you van shim it forward just slightly. That combined with a moved shocktower gets the shock/arm angle back in the std. position

I allways run the steeringblock low, since you moving your pivot point higher up the hingepin on the arm, that makes the height of your wheelaxle higher than normal anyway. So I want to keep the steeringblock as low as possible.
But rather than cutting the steeringblock, I prefer cutting the arm. I've never had it break in that point even when it has been lowered

Hope this all made any sense......
