I have always heard that MKIV GTI does have a front sway bar, but NOT a rear one. However, if you go to http://www.vw.com/gti/tech.htm you'll see that both 1.8T and VR6 have a rear stabilizer bar, 1.8T with an integrated one (whatever that means) and VR6 with 18mm one.
So, my question is, what's the difference between a stabilizer bar and an aftermarket sway bar? Don't they have the same effect? If we put a sway bar, should we take the other stabilizer out?
