Lowered car... uper control arm question

My 97 Thunderbird has been lowered using Eibach springs. I brought my car in for repairs after haveing some front end problems and the mechanic told me I need upper ball joints/control arms. He also said because the car was lowered I will need longer upper control arms to stop the front wheels from tilting inward.

Is this true?
Is there a part available that solves this problem?
OR
Is there another way to stop the wheels from tilting?

I did search the forum and I didnt see much about this issue any help whould be greatly appreciated...

You probly do need new ball joints, but that mechanic is an idiot. The wheel wont ever tilt in or out (unless your way out of alignment spec). Buy new Moog upper arms and you will be fine.

You mechanic is correct, however you don't need larger or longer control arms. What you need to buy is a camber kit from eibach to fix the inward pointing of the tire. Whenever a vehicle is lowered or raised you should always get a camber kit to keep your tires from going bad quickly. Without a camber kit you will wear down the inside of the tire because the wheel will sit at an angle. On another note, it is a good handling practice to have some camber and it will definitely help out on the turns. If you lowered the car more than an inch and a half or you just daily drive the car get the camber kit!! Save yourself money and time down the road.

You don't need a "camber kit". There's enough range on the stock camber adjusting bolt on the inner LCA to compensate for a lowered car. My SC has been lowered 2" for 15 years......

If you lower it 1 1/2 inches, and there is not enough adjustment on the lower control arm, them you most likely have worn parts. If lowering 2 inches or more, you most likely will exceed the limits of the adjusters. If so, read this.

I had my bird lowered 3" and there still was room for adjustment. No new parts required unless you have worn out components, which you should replace anyway.

My interpretation of all this is that the mechanic is trying to tell you that by lowering the car, you have now setup a situation where you will have negative camber gain as the suspension compresses. I looked at this on my car a while ago, but do not remember the details. At stock ride height, I think I recall the suspension produces mild positive camber gain before going negative. On a lowered car, the suspension starts out with negative camber gain. This is not necessarily bad. You want some negative gain so the tires lean into a turn. Some cars have been purposely modified to do this. You don't want too much though. This should definitely not be a problem with any of the lowering springs available on the market, so don't worry about it.

Hello

What is this camber kit? I could use more camber.
Where does it affect camber on a Thunderbird?

Front & rear kits?

The link 392bird posted is the only "camber kit" you'll find, and it's just a modification rather than a kit.

Needs more stall.
