Default Q's about outback FRONT sway bar, and WTB

Does anyone know the stock diameter of a BD outback front sway bar? I want more stiffness in the rear which means i want some thing in the neighborhood of 16-20mm for the front and if i can get away with an outback sway bar that would be cool, and does anyone have one that they would like to get rid of

I too would like to hear the definitive word on the diameter of the BD/BG outback front sway bar.

I have a 20mm rear bar (Whiteline BSR19X) and would like to upgrade the front a little to match (at present the car is a little tail happy). I've heard that the outback front bar is an 18mm item which would be perfect for me I think (based on the assumption that the stock GT bar I have now is a 16mm).

That said I am running rather high spring rates (559f/448r), with stock(ish) spring rates it seems like you may want the front bar larger than the rear to achieve a neutral balance.

Pat? any input on this?

My guess is that the Outback front is the same as the GT front. I think the GT front is 18mm, not 16mm, but I could be wrong. I might still have mine in my garage at home (I'm visiting family now) so I can try to remember to check next weekend.

You would even more so be considered "the man" or at least among people I use the adjective for if you sold your OEM one to me

I finally got around to putting a set of calipers on my front swaybar today...and it measured 20mm.

I'm fairly sure that it is a stock bar, so I'm not sure where I got the idea that it was 16mm.

That said, I guess I need to take the car and push it past the limit to see exactly what the handling is doing. Driving it on the street it seems like the rear bar is a little too stiff for the front but I'm not sure how that could be the case if they are both 20mm (whiteline BSR19X in the rear).

20mm is the stock size.

I asked Subiegal about this when she was clearing out some whiteline products.

I kind of wondered why Whiteline made a 20mm front bar, but depending on the construction, it might be more stout. I remember replacing my stock front bar on my Honda with a same size bar, but I did feel some handling improvement with the better made bar, even though it was the same size.

I got the 22mm front swaybar now, I think it is a worthy upgrade, more so than a front strut tower bar.

I have the 18-20-22 adjustible in the rear, and but have it set to the 20mm setting currently.

Diameter isn't the only factor... the length of the arms from the bolt holes to the centerline of the main shaft makes a difference as well, as is shown in adjustable bars.

?!...wait a minute, if the front sway bar on a GT is 20mm that would mean that the rear is the same size if not bigger right? Or is that why we suffer from understeer?

How about the Outback is that 20mm in the front too? What size is the L series, is that 16mm?

The stock GT rear bar is only 15mm (or maybe 16mm, it's been years since I had a stock rear swaybar). So the front swaybar is definitely bigger than stock.

I could have sworn I had done the 20mm Whiteline bar up front and the stock bushings wouldn't fit, but maybe I have the 22mm. Guess I'll have to measure. I did confirm that my stock front swaybar, which is sitting in my garage still, is 20mm.
