blackops

Hello Everyone.....well I was looking at possibly purchasing a RS4 Rear Sway Bar for my '02 A4.
However since I bought the car used I have no idea if it already has a different sway bar other than the stock OEM.
Is there any way to possibly tell if I have the OEM Sway Bar or some other?
I had it up on a lift last week when I was getting my APR chip and rear brake pads replaced and I did see the one that was on there it was black (not like that will help) but I did not bother to look any further. I also know now that the previous owner put the Eibach Pro Kit lower springs on it. So that is what got me to thinking if he may have replaced the sway bar.

Thanks for any advice

Just jack it up and measure it - with calipers is the easiest way - IIRC stock varied from 16-18mm depending on sport package or not. It should be obvious if it's aftermarket if the measurement is greater than that.
