If you plan on going coil over in the future why not use a tall, drop spindle?
This will give you the drop you want, the added height will correct the geometry, and you'll have a head start on the coil over project (later you can just add upper and lower control arms with coil overs and be done).
The only thing you'll want to watch is that you don't reach ball joint bind using a tall spindle and the stock arms.
If you need to replace the OE shocks you can use our new RQ mono tube dampers that have a 1,000,001 mile warranty.
