Default Why Did Subaru Change Rear Sway Bar Size in the WRX?

My understanding is that the 02 and early 03 WRX's had a 20 mm rear bar. Why did Subaru change this to a 17 mm bar?

I am looking to buy a 20 mm bar for my Saab 9-2 and there is someone who is willing to sell me the one off of thier 03 WRX. How can I make sure it is a 20 mm car and not a 17?

Thanks!

to make it more likelly that the front of the car breaks away into understeer than oversteer as the avarage driver copes with understeer better

So I guess there were several accidents causes by excessive oversteer or something that made them change this?

No there were not accidents...

the MAJORITY of the general public cannot handle oversteer

they react better to understeer.

that is all, really.

if you can get the VIN of the wrx the sway is coming off of
pm it to me
and i'll tell you what bar it had originally.

(i work for Subaru and have access to the database)

Thanks for the offer! I may take you up on it.

I just find it strange that they would change it after a year. You would think that Subaru would have thought of this when they released the car. Whatever....

Thanks again for the info.

or the could of changed the veichle weight, or changed suspention componants or geomitry or even just found a better suited material meaning they could use less of it!

likely

it was just easier to make one bar for ALL of the wrx's
rather than 2 different ones...

cheaper and easier production ya think?

It's called "volume discount" in my world of product engineering. It only makes sense for the manufacturer of anything to commonize components.

Whaa? I thought that the sedans all had a 20mm bar... 17mm was only for wagons?

02 USDM WRX sedan's and a very few very ealy 03's-after that all went to a 17mm

There were a few accidents unfortunately (can't say for any certainity if the rear sway bar played any role whatsoever), but a few unlucky folks did post that throttle lift oversteer played a role in some of their accidents. "Playing" on a curvy road is not the the most opportune place to find out about this phenomena.
