You are completely missing the point I'm attempting to demonstrate, I've already said I don't have first hand experience of VRS set ups. I'm simply making the observation that each vehicle is different and that you shouldn't confidently recommend parts unless you have tried those parts on exactly the same setup. Internet forums are full of well meaning enthusiasts who sometimes fall into believing half truths and forum myth. I'm not suggesting your advice wont work, simply that you state it as if you can guarantee it's the ideal set-up for the OP, I'm simply trying to warn anyone reading this that you can't bolt any part to any set-up and get the same results. As for trolling, have I typed anything that isn't helpful or factually correct? Cutting and pasting, LOL, I am a vehicle engineer with nearly 30 years experience with manufacturers and race teams.

The fact that the OP already has coilovers makes a generic suggestion dubious from the outset. If the OP has the coilovers at a reasonable ride height he's already reduced the body roll with the increased spring rates. Also if he's added a certain degree of rake to the car then this will influence the roll couple distribution. If he's lowered the car massively, has the camber been corrected to suit, what is the dynamic camber arc at his given ride height. Any of these factors means that offering a generic suggestion may not work with his setup. I understand that you are offering your experience to be helpful but if you don't give more detail or qualify your answer then any forum reader runs the risk of buying and fitting an inappropriate part.

Far from trying to embarrass anyone I am actually trying to help the vast majority of readers with only an enthusiasts level of suspension knowledge. Too often I have spoken to people who have spent large amounts of time and money modifying a car based on other peoples suggestions only to be disappointed or at least frustrated with the results. When people make blanket statements about specific components or models it shows a lack of basic understanding of vehicle suspension and dynamics. A suspension system is just like an engine, it's a sum of its parts, not an individual component. In the same way you wouldn't bolt together a random turbo, head and exhaust and expect it to work to it's best potential, neither can you do this with suspension. Things that effect how effective or ineffective an ARB is depends on so many things, tyre width and profile, bushing, spring rate, damper rate, ride height, dynamic and static camber, body rigidity and body configuration. That's just off the top of my head, change any one of these factors and you will alter the results. If you are going to suggest someone spend their time and money based on your opinion then you should be specific about the details, otherwise they could end up at best out of pocket and disappointed, at worst with a dangerous car.

If you or the OP had a proper understanding of the operation of an anti-roll bar and it's influence on handling and interaction with other components you wouldn't have written that post. I used to own a Polo, didn't make me Jari-Matti Latvala. I am not 'right in a sense', I am just right. You cannot compare ARB's based on diameter unless they are made from identical materials, go through an identical heat treatment and have identical bend/blade configurations. I will bow to your personal knowledge of specific bar comparison as I don't have that experience but without qualifying which bars you are referring to your comments could be very costly and misleading.

Hi, I was reading this thread for a friend who's recently bought a VRS and thought I'd just point a couple of things out. You cannot compare ARB's by diameter, even OE bars can be made from different materials making their torsional rigidity disproportional to their diameter. This is just wrong, an anti-roll bar and a sway bar are identical items, Europeans tend to use the term anti-roll bar and our American cousins call them sway bars. Also you can't make blanket statements like 'Every vRS would benefit from a little extra bolstering on the rear' without a full understanding of suspension tuning.
