The stock EVO rear sway bar is 22mm diameter, the RRE rear bar is 25mm diameter. It includes new brackets and urethane bushings. You will re-use the stock end links, they are a ball joint type. The holes in the ends of the bar give three adjustment positions for fine tuning your handling.
This rear sway will make your car handle better by making it more "neutral". Stock, the factory gives you a car that "understeers" some. When you have the car all leaned over at the limits of adhesion, the front tires have a little less grip. The front end "pushes" some and does not turn enough. From instinct, you let off the gas because the car is not turning enough. This makes the weight transfer to the front of the car. The front end gets a little more grip and the rear a little less, your car rotates and you make the corner fine. All is good.
All is good except this is not the fast way to drive, having to let of the gas to make the car turn. It would be much faster around a corner if you could keep a nice steady throttle through the corner, gradually feeding in more throttle as you pass the apex and straighten out. The car would drift all four wheels evenly. Nice small inputs from the throttle transfer weight to the front or rear depending on where you want the car to be. A little more gas transfers the weight to the rear and the car goes wide, let off slightly and it sharpens up the corner. This is a neutral handling car. By installing a thicker rear sway bar (and leaving the front bar stock) you will make the car more neutral.
The down side, you need to be careful of what you wish for. If your car is nice and neutral, when you chop off the throttle suddenly the car can kick the tail out. The rear bar is made with a street car in mind. It is not a crazy stiff bar, it is even adjustable. There are three adjustment positions. It will make the car more neutral though and you need to keep this in mind. If you add a front bar, the car will corner flatter and give you a false sense of better handling. Also the bigger front bar will lift the inside front tire when cornering hard. This will give you less traction just when you need it most. We do not offer a front sway bar.
|The stock rear sway bar bracketry limits the diameter that that you can go if you retain the stock bracket. we use a completely new reinforced bracket.|
|Unbolt the stock sway bar from the end links using two 14mm wrenches. If you live in the wetter areas of the country, you may find this difficult if not impossible. Soak the threads liberally with a WD-40 type lube over night. If you cant get these nuts loose, you may need to buy new end links. Try loosening these first before you get in too deep. If possible, try loosening them even before you get the bar to see what you are up against.|

|Check the clearance between the bar and the aluminum crossmember. You will need to adjust the bar so that it sits right in the middle of the crossmember.|
|Once you get the clearance that you need, tighten all four bushing bolts.|
|The bar is adjustable. By moving the end links to the more forward holes, you make the bar softer. Moving the end links towards the rear holes, you will make the bar stiffer and the car will be more neutral. Play with the car on your favorite road in the softer settings first. Then cautiously adjust it stiffer if you like.|
