When is an aftermarket TA, PHB, and LCAs needed? I am looking into starting my build of my 94 Z, and was wondering at what point will aftermarket suspension pieces such as a new Torque Arm, LCAs, or PHB be needed? It will be a street/strip Daily driver through college, and will have a Eibach Pro-kit with Bilsteins in the near future. Thanks.

i did lca's and a phb with only a lid and catback. the wheel hop was ridiculous. problem solved.
if it's a mostly stock car and you don't have any wheel hop issues, then i wouldn't spend the money unless it's itching to be spent.

* Adjustable LCAs allow you to adjust the rear axle forward/aft/diagonally.
* Adjustable PHB allows you to adjust the rear axle left/right.
* With both you can adjust the rear axle in all horizontal directions (left/right/forward/aft/diagonally) to center it under the car.
* Ajustable PHB isnt necessary for stock right hide, but is necessary when the ride height is changed (ex: lowering the car).
That being said....
I have stock right height, but I do have adjustable Spohn rod/poly PHB and LCAs. My rear was a bit off with the stock parts and is all straight now with the adjustables. I had it aligned by the tech during a 4-wheel alignment. It took some convincing to get him to do it. He insisted that there wasn't anything adjustable back there. I had to walk him over and show him.
When I say centered, I mean with the running gear (during an alignment) and not just visually.
