I'm interested in getting an aftermarket adjustable rear sway bar and I have few questions.

1) What to choose between different sizes? Stock seems to be 22mm and
popular sizes are 24mm and 25mm. Why 24 or 25?

2) Hotchkis one is 24mm and it's hollow. Except for weight loss, any other advantages? What about the strenght of such bar?

Thanks

Thicker, lighter, same strength on most of them, they make big difference on autox with proper suspension tuning.

I know, that's why I wanna get one because 1st I hate how the car understeers heavily and 2nd I've seen many pics of stock Evos with one wheel in the air.
But in order to make a decision I'd like to find out which one is best

 

I just ordered the Hotchkis due to the positive feedback and the weight. I'll let you know when I get it and put it in (although it'll be a while before I get a chance to install it.)

 

The hollow swaybars are usually made of cromoly tubing which is strong and light weight. The solid bars are made of a more mild steel so they need to be solid to provide stiffness and this makes them heavier.

I just got a Progress Group swaybar today. It's 25mm, solid, and comes with new mounting brackets. I'll have pictures of it tomorrow, and some comments to come. I got a deal on it through a friend at a discount tire, $148.

 

I highly recommend the Hotchkis from GSC Motorsports. Light, strong, great price, great service!

 

I recommend the Cuzco adjustable sway-bar. Adjustable to your taste of driving, and they've been around on Evos for a long time. There is no need for a hollow bar. The weight loss is good for some though, but no performance gain is noticed over standard spring steel.
