In a word, NO. Great question though...
While a radical drop in ride height can cause the pinion angle change, the 4 bar setup we have doesn't allow a large change. So, as stated, you don't need them, however, you could benefit by tweaking the pinion angle...that is if you spend a lot of time on the 1320. And if you are dropping it, I'm guessing you don't. Otherwise, I wouldn't bother.
Nonetheless, if you don't have LCAs, I'd highly recommend em, for street, strip, auto-x or anything in between.
Don't bother with the bumb steer kit, get the Motorsport ball joint kit instead. As far as I can tell, unless you are doing straight drag you never need to change the rear upper arms out, just replace the rubber bushings when they get old. A nice set of lower arms wouldn't be a bad idea however.
They also recommend replacing the stock bushings in the uppers. I am just getting the MM uppers(basically FRPP ones with MM bushings).Great answer...
UCA's are actually going to make your handling even worse since the stiff bushings dont allow correct articulation of the axle & they cause sever bind...If u check out Maximum Motorsports website, they recommend sticking with the factory uppers unless u switch over to a torque arm. Aftermarket LCA's have also been known to damage upper torque boxes too... LCA's would be a great upgrade to make....
if you get a torque arm and a PHB you can remove your UCA's, cant you?
This is what I want to do....
