Introduction
This is an easy performance upgrade to perform and will run you approximately $175 in parts.

There are a couple different brands you could go with:

Stock: 20 mm front and 13 mm rear
C32: 22 mm front and 16 mm rear
H&R: 26 mm front and 19 mm rear
Evosport: 24 mm front and 19 mm rear
Eibach: 24 mm front and 22 mm rear

I recommend going with a H&R front and a Eibach rear.

Installation Procedure
 
1. Place rear of car on Rhino-Ramps or other suitable device(s). You have a choice whether you want to get under the car and make it a SAFE one. Take no chances with your life (Figure 1).

2. Remove 16mm endlink nuts on both sides while holding the inverted torx bolt on other side with a 12mm wrench (Figure 2).

3. Remove two E12 Inverted Torx bolts on each side (Figure 3).

4. Take car off Rhino-Ramps, jack up right-rear side and remove wheel.

5. Pull Swaybar out through that side (Figure 4). It will take a little while, but dont give up.

6. Put the new swaybar back through the same path. Replace the wheel and tighten the bolts in a star pattern to 100 ft-lb. Place the car back on the Rhino-Ramps (Figure 5).

7. Put swaybar in the endlinks, do not put nuts back on yet .

8. Put the two E12 Inverted Torx bolts back in on each side as shown in Figure 6.

9. Put the two 16mm endlink nuts back in while holding the inverted torx bolt with a 12mm wrench (Figure 7).

10. When installed with the larger rear sway bar, there is a lot less understeer. The car turns a lot stiffer and has less body roll.
