You can improve things greatly by installing better pads up front (skim the discs, too) and making sure the rear drums are in proper adjustment - MOST CARS' ARE NOT. The next step is 'Bolt-on' upgrades such as using the Type 3's larger rear drums and front callipers (over your non-vented Beetle front discs) which is what many of us have had over the years on Beetles used for circuit sprints etc. Still not enough? Then fit better-quality brake linings in the rear drums (plus machine them) - that will cost you another $100 or so and works really well. Rear discs will cost you around $1000. I installed vented front discs (and rear solid discs) to my Beetle as part of a kit I have been developing for a while now

and the bill was more than double that and although they work sensaish, they are almost "overkill" engineering for the street
