My .02 cents?
Unless you're planning on constantly raising and loweing the car for potential road racing or auto crossingg purposes, or corner weighting the car to ensure that its as close to 50/50 weight distribution, its not worth the effort.
Almost all of my friends that drive gasser veedubs use a quality cup kit,h&r makes a very good set. A 60/40 cup kit will be perfectly fine for daily driving giving you a lesser wheel gap and lowering the car a decent amount, however if you want to go even lower, a 60/80 cup kit will satisfy that need.
40,60,80 refer to the millimeter measuerment of drop, and it is a good way to give you that static drop.
If you do eventually get yourself a cupkit and want to break in the springs to get the proper sag, get a 100 pount weight and put it in the passenger seat to balance the weight so the car rides correct after.
And don't forget to upgrade the front control arm bushing! It makes a world of difference when driving with the new suspension!
As an aside, if you want fron chin scraping low, again with h&r, they make the ultra lows, which can dump the car to give you massive wheel tuck to the point where the control arm mounts are almost scraping the ground.
Remember to bank some cash away for oil pans though
