I'm confused. The OEM RSB is 13mm. You want to go with a 20mm bar? Or you want to go bigger than 20 because you already have a 20mm on there?

If you want an 18-20mm bar, go with the WRX or STI bar. You can get one with bushings and brackets for $40-$60 shipped.

If you want to go bigger, try Whiteline, Rallitek or Cobb Tuning.

Cool thanks alot. What do you know about strut bars? :)
+1 for the RSB. I just put a 20mm on my WRX wagon(wagons came with a 17mm) and even a 3mm increase was a big difference. You will love what extra mm's will do for ya. Anyways, alot of people will say that a rear strut bar is better and that a front is useless. While doing the rear is a good improvement, IMO, the front is a worthwhile mod too. I had a Cusco front strut bar on my RS, and I could tell a difference immediately after installing it. Now, dont expect anything drastic, but overall, turn-in seemed better, and the car just felt more together.

PLEASE PLEASE search the forums before posting. There are a LOT of threads on swaybars; it's one of the most common modifications, and this forum's been around a long time. The math is inevitable. :)

Here's a Sticky from the top of this very forum, with some helpful info:
