I just had the Porsche Big Red Stage II package from Eurocar Service installed. It makes a huge difference in braking power on these cars and is a very worthwhile mod on the otherwise weakly-braked UrS4/6. Thanks to UberS4 for turning me on to this package which was a reasonable $1300 and little trouble to install.

Not to mention the fact that Tom at ECS is one of the few tuners out there that's willing to stay on the phone with you and help diagnose a problem without rushing to see what it is that you want to order. 2 "situations" that I did have with the kit is: If you're using the stock wheels, which I do in the winter months, the 5 mm spacers do cause a light vibration and must be mounted with the beveled edge facing inwards. Also, although Porsche brake wear sensors are included with the package, I opted to just loop the circuit, as the soldering tends to come undone after a few hard braking sessions. Besides, I change my pads twice a year, so I don't really need that Autocheck system...it causes more problems than anything else. Other than that, though, I love my setup and wouldn't change it for any BS BIRA setup, monoblock or not. The beauty of the kit is, even if you get the stage II, you can always upgrade to stage III by simply getting the cross-drilled rotors directly from Porsche when it comes time to do so. A word of advice, though: With the hard braking, the stock shocks tend to wear out sooner, just one more reason to fool around with the suspension...God, I love mods! :-)
