lowering a new but not new new beetle

[Danny8]

hi guys, this is my first thread apart from in the newbie area so be nice. ive spent a couple of hours searching and reading and still felt i needed to ask here.

the car is a 2002 beetle.

before i go further ill say that coilovers are not an option.

want it to go as low as possible and ive read some issues about the front sway bar causing issues if you try to go to low.

from what ive found i have 3 easy choices.

eibach pro kit with an estimated drop of 30mm for $350 for the set

h&r list three part numbers which will i think all fit the beetle
29489-3.....29489-2....and 29489 for $460 a set

the other option is low king springs for about $300 a set.

the question i have is....

is there any difference in quality from the euro stuff to the kings? does anyone have first hand experience of which will be the lowest?

will any one brand be stiffer or affect ride comfort over any other?

i have king super lows in my corolla so i understand how stiff the ride can be.

what do you guys think?
