Default 22mm vs. 22-24mm adjustable front sway bar

I'm thinking about adding a new front sway bar to my 2.5RS and I have a question - is the adjustable 22-24mm front sway bar worth the extra money? I have a 2002 model that I run in GS on Kumho E700s.

The cost difference between the 22mm bar and the adjustable 22-24mm is about the same as a set of mud flaps. It snowed again today and my doors look like terrible covered in all the black slushy goo.

Thanks for the help.

Chris

I don't have experience with the adjustable bar. Also, I have a '99 2.5RS, so my results might not be of help.

I run the 22mm MRT front bar. I like it quite a bit. I'm not sure I would need anymore though.

There's been a lot of debate about the use of a front sway bar in the Suspension forum. The problem is that Imprezas understeer pretty badly. Most people correct this with a rear sway bar. Adding the front sway bar(assuming you have a rear bar) could make the car understeer again, only flatter.

If you have a rear sway bar, you probably won't need the adjustable bar.

Unfortunately, changing the rear sway bar is not an option if I want to stay in Stock. I understand that understeer could be an issue but right now my biggest problem is the wallowing of the front end (the other guys in the region call my car the S.S. Impreza - I've had people get car sick when riding along during a run) so I'm willing to risk that in order to increase the responsiveness to turn inputs and reduce some of the front roll.

A larger front bar will nonetheless induce copious amonts of understeer when you need it least...

Go with the cheaper bar since you probably won't have it on for long...

With my G-Stock setup on my '99 2.5RS, I did not find any increase in understeer when going from the 19mm to the 22mm front bar. By keeping the car flatter, there is less camber loss during hard cornering, letting the tires work a bit better.

In fact, I found turn-in sharpened up a bit, and the car actually came off the corners with a bit less on throttle push. This is not to say I don't have some understeer, but with proper tire pressures, shock settings and rear toe settings, I have learned to dial a lot of this out.

I was mildly competitive last year on the national scene in G-stock with what I consider to be a very basic setup with off-the-shelf parts.

I am currently, and have been running for over a year on a 25mm front and 24mm rear sway bar settup. I have NO understeer. As a matter of fact it is quite easy to induce throttle oversteer with this settup. There is also a local Legacy driver who has had fantastic results with a 25mm front bar and 22mm rear. I also know of several other Imprezas with 22mm on the front that they are extremely happy with.

This is on a MY00 2.5 RS.

I even had the rear sway bar mounts break once during an autocross and didn't know it until the event was over. Even then the car was only mildly pushing.

Our best guess as to why this is, is that the larger front bar keeps the mass, and therefore the weight, from transferring outward in the turn.
