For Starters

Basic Mods for the beginner to start with

SA/FB Rx7s responds well to left foot braking, high entry speeds and fients. Power, angle, and hydro for beginners is a crutch. It's a huge crutch that will make you suck later on.

Imho if you weld the diff, and remove steering locks, add some air pressure in rear, PB&J mod the watts and just run it. You will have a solid start that will allow you to learn how to drive. As you progress you can start to add these mods as you grasp your technique and improve to the point you can utilize everything that the car already had.

Rear Axle
How to fix our Cars weakest link

Basic overview of your factory RX-7 Suspension:
Lowered car, factory 4 link suspension with a watts link.

The lower trailing arms are straight, but the uppers angle inwards from the rear end, and are much shorter than the lowers. This causes a few problems. When you lower the car, the axle will pivot and cause extreme wear to the axle pinion and trans tail shaft. Also, when you enter a corner the axle will pivot at an awkward rate and finally hit a point where it will bind up, normally causing snap oversteer. The Watts link is not centered on the diff and the bars are unequal length. This causes the rear end to act slightly differently on either a left or right turn.
