Do you plan on doing any road racing ? When ever you lower or raise a car it effects
the handling greatly. Usually lowering for the better raising not so good,but you have to
consider ground clearances and the area you drive in. If I were to lower mine two inches
and the roads I drive I'd be in real trouble . Anyway adjustable is better if it is a quaility peice.

If you want to adjust pinion angle, you'll need adjustable upper control arms. Dropping the car 2" will change the pinion angle....
