    I heard that post-90 spec beams were "beefier". What does that mean? I might have found a rear beam for my Mk3 but it's from an '86 Mk2 - will it bolt up OK? Is it just a bit heavier?

    ive never seen any solid evidence or info to show what the differences are between different beams, it should fit fine as long as the rear brake bias valve fits/works with your car

    G60s have a thicker anti-roll bar than GTIs.

    so ring up VW breakers and ask for a corrado g60 rear beam

    I know this is an old thread but i have had a 90 spec beam next to pre 90 spec beam. The differences between the two are;

    90 spec has more gussetting around the trailing arms and is therefore more beefie.

    90 spec also runs the solid break lines in a slightly different way.

    Both of the beam have the same mounting points and are both fully interchangable between 90 spec and pre-90 models.

    I know this because i helped my brother strip a rusty 90 spec valver that had a polybushed beam, we then moved the beam over to his 89 model and realised the beefiness of the 90 spec beam.

    No pics and it was about a year ago. Both beams are on cars ATM.
