The rack spacers kits move the rack up as far as possible. Sheet metal prevents further raising. The ERP bump steer kit replaces the tie rod end with one that spaces it out, leveling the tie rod. You can use the two kits in combination.

As for your alignment woes, I'd suggest you find someone who is experienced with 911 suspension alignments. Experience makes all the difference here. A knowledgable person can do a few tricks that the manuals don't tell you about, and get much more range especially on the rear.

It's possible you have a bent trailing arm, but highly unlikely that both are bent. That your guy can't either side in spec is an indicator that the problem may not be a bent arm. The rear adjustment technique is particularly perplexing to the average alignment shop guy.

There are no aftermarket trailing arms. If you have a bent one, source a replacement from a pcar boneyard.
