H&R Touring Cup Kit Questions

[Bucky]

I recently ordered an H&R touring cup kit for my 2003 Golf. I have been reading that some of the earlier models 99.5-2002 need a front lower sway bar, but not for later models. Also i read this on the H&R site When lowering the chassis more than 1.4”, and your vehicle has a 42mm or larger drive shaft you must use one of H&R’s Volkswagen front sway bars to accomplish adequate drive shaft clearance. As i'm a total NOOB i have no idea what my drive shaft length is. Not sure if this applies to all MKIV's . Just seeing if anybody has installed this kit and have had any problems or what problems could possibly arise.

All input is greatly appreciated.
