Uprated antiroll bars for B4/BE legacys?

[Optical]

I see a whiteline fixed 20mm and a cusco adjustable 18mm available in NZ.

What other options are there?

If its for the Prova car would custom machined ones be out of the question? Zerosports will probly do some horribly over priced jobs too.

Yes prova legacy, dont know about getting custom ones... sounds like a drama

stock BE bar is 17mm so anything will be an upgrade and impreza bars dont fit

[PhatRS]

Custom ones can be heated and bent at places like George Stock & co down here or you can get a bar splined and mounts for the links put on. I dont think its too much work although you might need to know what size you want to go to or have them made up adjustable.

Probly not much around for the BE as they are the only models with multi link rear suspension arent they?

[funkytown]

the front of a GC mounts up to the BE front end i thought?

the rear like Jonno said is multi link - but afaik the BP / BL have the same arrangement which is then shared with the 2007 sti so maybe see if they are similar or the same?

Im pretty sure whiteline do a 20mm adjustable - isn't the stock one a mere 16mm ?

Symms, Laile, STi ??

I know of a few other japan brands, but weather they still stock them nowdays is the question.

how about making your own "Torsion bar swaybar" setup like the WRC cars?

Why do you want to change them? Bigger is not always better. If you go too big on the front you will understeer more. You need to change antiroll bars either up or down depending on the tendency to over or understeer. Just going bigger in the front will not allow you to corner any harder, if a 20mm bar made the car handle better Subaru would have made it that size. Anyway if you must go bigger make sure you do something with the back end too.

To an extent I agree with your statement on the changes experienced when changing anti roll bars around.

However it is not strictly true that an item fitted by a manufacturer must be or is better simply because it was fitted as standard especially when the benefit or detrimental effect is negligible when compared to cost when it comes to OE fitted equipment as manufacturers tend to put alot of weight on cost savings...

a 20mm bar may have cost more (probably does over a 16mm bar), so savings talks when building cars... They would have RnD'd to the point where they could dial out any worries via other easily changeable and cost effective ways that would have saved them a motsa over fitting the bigger bars...

i.e. $0.10 savings over 200 000 cars = $20 000.00...

I think it depends entirely on the current handling/setup of the car and what you are trying to get out of it. I doubt that Optical doesn't realise the implications of going to bigger bars and at a guess, the Prova Legacy is a wee way off being a standard car anyway.

Bit of an understatement.

ah whoops i should clarify im talking about the rear bar only, front is ok for now/less important.

Impreza bars do fit the front but the rear bar is very different.

Interesting thought about the GRB bars, might be hard to find one to test fit...

Couldnt see anything applicable on 41auto, might just have to go for the whiteline one

There are a few slightly larger ones in the US but shipping would be prohibitive.
