Anti-roll bar and poly bushes

Right i'm looking for some help here.

i'm finding the steering on my 98uk 80K miles seems to be a bit sloppy kinda not as crisp and responsive as i think it should be.

I've read that changing the anti-roll bar to a stiffer one and also changing the bushes to
polyurethane will greatly improve the responsiveness.

my questions are:

Will these 2 things alone improve the steering?


How many bushes will i need to replace for best results or do i buy a whole set? (how many in a set?)


Will i experience greater road noise and more vibration on the steering wheel, and if so how much more?

Or do i just replace with new standard anti roll bar and rubber bushes?

I would be grateful for some help here

I would have to say that a good rear sway bar/bushings/endlinks will definetely help, I'm not totally sure about the stiffer front sway bar. I have heard that the front is a little harder to install and it can cause some other problems.

You can probably get some new bushings for the front, and go with something like a Cusco sway bar for the back. You can also get endlinks with bearings in them instead of bushings, and that should reduce noise and should last longer.

Oh another thing to make sure of (at least this is true on my US WRX) make sure if you get new endlinks that they will allow the rear sway bar to clear your exhaust system. That is if you have an aftermarket exhaust.

Hope some of that helps Newie!

If you have play at the steering it could be the knuckle joint from the rack to the bottom of the column which might be the only problem.

Just an idea but I have a look when I see you.

I think Neil is probably right, hopefully you guys can determine what is causing the excess play.

Now I have noticed on my car that the steering is "vague" feeling, like I can turn the steering a little but the car doesn't respond.

Maybe that is what you are feeling? Unfortunately the steering with the US WRX is kinda sloppy, it's not terrible, but it could be MUCH better with something like a quick ratio steering rack. Maybe you should look into that newie? I think rev lab makes them?

newie, if you start to price them let me know what you find. Depending on the price it could be something to save up for. And I'm almost positive a good subie mechanic would have to install the quick rack steering, I wouldn't even attempt that one.

honestly that is one of the very few things I would change about my car, a more crisp steering response. and much less understeer. maybe those two problems could cancel each other out?

leave the bushes as poly bushes can be a real noisy pain in the arse- although they do sharpen things up they've never been high on my list.

leave the ARB as you can dramatically alter / upset the handling of the car.

change the droplinks for solid ones from whiteline- available from http://www.j-w-racing.com/ Easy to fit yourself and will firm things up just nicely.
