Compiling Stock Front Sway bar/RSB size chart

All these rear sway bars should be interchangable. STI bars are said to fit regular imprezas if you bolt them to the outside of the endlinks.
Non-turbo FSBs will fit non-turbo cars.
Turbo FSBs will fit turbo cars.

according to one of the mods, 90-99 Legacy bars do fit 93-07 Imprezas. NA to NA and turbo to turbo, of course.

Many thanks to those who're helping this thread along.

would a legacy bar fit an impreza? I wouldn't think so normally. They have a wider track no? (at least the newer ones do)

Also -- Road Runner. I don't have time to curate this thread anymore. Would it be possible to open editing privledges for the OP to everyone?

i might be headed back to that yard this week and ill try to get pics, the preduction code on the door jam sticker was 4/99 unless this guy had some stuff done to it i thought they were heated and leather...might have just been the overwhelming joy of finding a set of sways front and rear for 30 lol

sorry guess i wasn't clear

was frustrated that there's nothing better than the rallitek 22mm FSB for us NAs. i'd REALLY like a 27mm FSB to go with my cobb 25mm RSB on middle setting. tribeca FSB doesn't seem like the best route to go either, being it's effectively a 22.25mm. :(

anyone have luck using 27mm whiteline bar on an NA with stock headers?

I have a whiteline 22-24 on my N/A RS...

I believe those are still avail...
