I tried searching for this but I didn't find the answer. Will a RSB from an 05 STi fit on a 02 WRX WAGON? I found a nice price. I know the endlinks will not fit. If it will fit what is the diameter of the STi stock RSB and will I be able to use my stock endlinks until I get some upgraded ones?
The endlinks would not be a problem. You'll need to swap the mounting brackets from an 04+ wrx/sti. You can use you're endlinks, but the bar will need to go on the outside of them rather than inside, and could eventually snap them in half. The sti rsb is 20mm I think.
Only 20mm? I was looking for a sedan RSB as a cheap alternative to what I really want. I eventually will get 25.4 mm front and rear bars. I can get a 02-03 Sedan bar that is 20mm and use the stock brackets so that may be the best budget solution out there.
