I just installed lowering spring and the back is at 27.25 inches. Are adjustable LCA needed? I may get a new driveshaft adn want o to make sure the pinion angle doesnt need to be changed. I have a V6 also.

 

what springs were they? how big of a drop is it? anything over an inch usually requires an adjustment. I installed BMR springs over the weekend, I still need to install my adj. upper control arm, adj. panhard rod and lower control arms with relocation brackets. I'm going to do it friday and get a full alignment saturday

 

eibach pro kit about 1.5"

 

mine dropped 1.75 in the back. I would jus get the adjustable control arms, this way you can always adjust it. I'm pretty sure that 1.5 will throw the pinion angle off

 

You can drive the stock drive shaft and Eibach-Pro without adjusting Pinion. It will be fine. If you put in a one-piece DS in future you will want either adjustable Upper or Lower arms at that time.

 

You can really get LCA Relocation Brackets if you have just fixed LCA's prolly and get an adjustable upper if further needed. Correct?

 

relocation brackets just re-adjust the angle of the lower control arms to get rid of wheel hop. The adj. upper control arm is for adjusting pinion angle on the driveshaft

 

I already have a 1 piece drive shaft. I have the V6 mustang with the stock shaft.

 

What he is referring to is the aftermarket aluminum drive shaft like the Shaftmasters, not the stock V6 drive shaft where you can see the slip joint easily. Everyone refers tothe aluminumas "one piece" when talking about the aluminum - you can really see the 2 pieces of the GT because of the center section that is exposed on that one.
