Will I need an adjustable panhard bar? I'm going with the roush rear springs and I already have an adjustable UCA and fixed LCA...

 

you wont need anything at all. i have the roush rear springs only and you'll be fine.

 

+1 Roush springs

 

No adj panhard needed. Unless you are **** or have oversized
tires and they just clear the fenders before the 3/4" drop.

44" long panhard bar at 2 degrees to the axle tubes OEM.
Now lower it 3/4" and do the math. Its less than 0.100
thousands of an inch shift to the drivers side.
Math is your friend.

 

Thanks for the information guys. Will I need Relocation Brackets for the LCA's? I have an adjustable UCA...

 

for that drop and having an adj UCA.....IMO no you will not need the relocation brackets. Check your pinion angle before and after to be sure but TacoBill did not need the brackets for a 1.25 inch drop.

 

Thanks mygt500...so leveling out the car by lowering the rear...would I get any more performance advantages?

 

Yes, its kinda like LCA relocation brackets but without the brackets.
You bring the front LCA mounts closer to the ground than the rear
LCA mounts on the axle tubes with the installation of lowering springs.
The difference is slight but there is a difference and its for the better.
The axle is now pushing the vehicle more forward instead of upwards
as with the OEM rear ride height.
