You need to get your Ducks in a Row.
Start by figuring out what you want to do with your car.
Sometimes all you'll really need is good shocks and bushings, a proper alignment and a set of average swaybars (PST ,ADDCO,) and you'll be happy.
Before you consider the Hotchkis UCA make sure your foundation is sound, Start with your Ball joints and bushings, Shocks, Then Subframe connectors, then Start the Hotchkis ball rolling,
Front and rear swaybars,
Strut bars,
Torsion bars ,
Upper control arms.
Now your into better brakes
and finish it off with Better tires and rims.
Good luck
