Upgrade rear sway bar
 

What is the diameter of a stock sway bar on a 2011 T5 with auto transmission? What would the next step up be? Does a R-Design have a larger rear bar? --TIA

IPD sells a C30 rear bar upgrade kit thats 25mm from what I recall - check that out as well as their install PDF. I used their kit on an 850 and it was a great add.
