My thread is so lonely. Show it some love!

 

...I bought a 20mm R off a guy that had an older than 02 sedan...I'm pretty sure it was the stock one from that car, I replaced the 17mm one that came on my 05 wagon and it measured correctly with my calipers, so I think the sedans before the bug eyes might have come with 20mm rears...

 

Mine's 25mm ******! :P

 

is this outside of the USDM market?

I've had multiple peopel tell me that usdm 97-01 cars are 13R.

 

04 Forester XT:
20mm Front/ 17mm Rear

20mm STi rear bar will fit on a SG Forester.

 

Updated data.
