You don't have to remove the calipers or rotors, only the soft line to the rear firewall, remove, the parking brake cables, the 2 shocks, springs and the bolts from the trailing arms...that's all.

twin pretty much covered it, but dont forget the driveshaft u-joint straps too! sway bar end links to the body will have to be removed (but probably will brake, dont worry, they're cheap to replace) as well

Re: 9 bolt rear removal
Is there a special way to remove the springs with out doing it with a spring comPressor also I was looking at a to get a new pan hard bar an track brace bar but no one sells a aftermarket track brace bar it's the bar that's above the pan hard that bolts into the frame by 3 bolts on the drivers side quarter panel

Re: 9 bolt rear removal
stick with the stock track bar brace, no need to upgrade. also, there have been some fit issues with certain "upgrades". upgraded panhard's not a bad idea if your bushings are shot in the factory piece; go with an adjustable one if you plan on lowering at any point in the future.
as for springs, TTop350 covered that - no compressor needed. Put the jack under that side and lower the axle slowly after removing the shock and the spring should fall right out.

I figure the situation in this manner: If the piece was a worthwhile upgrade, companies such as Spohn, UMI, and BMR would have already jumped on the bandwagon.

Re: 9 bolt rear removal
Yea this is true Ive been on plenty of aftermarket web sites to try an find the track brace bar but no one does it so I'll just stick with the stock one for the pan hard bar an rear lower control arms I saw a link on here for founders performance ones that are also adjustable how would u guys rate these of a scale of one to ten on performance an cost wise
