Installed my progress rear sway bar today.. WOW.. body roll is massively reduced... you can commit to fast sweeping corners so much more.. do yourself a favor and install one .. even though its not a performance mod and it will add a extra couple of kgs.. but the handling will never be the same.. you can put down power earlier as you exit the corner.. that favorite corner that you take day in day out on your way to work.. it will put a smile on your face : ) i got mine from ebay seller 240ish delivered.. took 2 a bit weeks. pm me if you want the seller.. install was super easy.. my advice take one wheel off..
