Lowered the bird an inch...
I was on lunch break today and started doing some reading on third gen. Came across the "lowering 101" thread and realized that I had my car lowered an inch and saw that I should install the adjustable panhard bar, LCA relocation brackets, and an adjustable torque arm.
Is this important if I only put in the eibach pro kit? (1") I haven't really noticed and unusual tire wear or ride.

Re: Lowered the bird an inch...
It's my daily driver. Like I said, no unusual tire wear or anything. I had it on a lift the other week and figured I'd spin the tires and check for anything out of the ordinary. Lowered it a little over a year ago.

Re: Lowered the bird an inch...
Might need the adj panhard bar - a 1" drop can move the axle towards the pass side some - just have to look and see if your pass tire sticks out farther than you driver side. No need for toque arm or LCA's. Other than that, there's nothing in the rear to get aligned. If all you did was springs without changing tie rod ends or centerlink, no need for an alignment. But like you said, no bad tire wear so your golden.

Re: Lowered the bird an inch...
For a lowered car I would suggest adjustable shocks, rear adj.LCAs/brackets, adj.PHB, and alignment. That is, of course, if your doing things correctly. You may not feel you need the control arms, but once you get some really nasty wheelhop you may change your mind

Re: Lowered the bird an inch...
Yeah, I prefer to keep my rubber on my rims rather than on the pavement, so no wheelhop here. Some see tire spinning as fun, I see it as a waste of power and a loss of the race. Now on a strip car that's a whole different story. But redlight to redlight makes no difference on a mild engine car.
