    I'm looking to upgrade the rear roll bar on my 2003 spec c. It came with 20mm from the factory.

    What is the stiffest factory subaru roll bar that will fit?

    The STI pink is 21mm
    The rb320 is 21mm with two adjustment settings.

    Which is the better of the two?

    And is it worth it the bother for 1mm change?

    Does your car have rear pink arms ? The roll bar options are limited if you do as the arb is significantly shorter. The STi pink bar comes in S202 and normal STi fitment and the RB320 bar is slightly longer again. :)
