My car has the brake upgrade, I would be afraid of it if it didn't!! Due to my rather 'spirited driving habits', good brakes are essential! I believe that Joe said it best when he said; if you make it fast, make it stop fast also, or sumptin like that. I actually want better brakes than the upgraded ones. Now that the car is going faster, the need to stop has increased 10 fold! Oh by the way, I highly recommend a 2-stage boost control. It allows you to switch to a higher boost when you want, but allows the car to run at a lower boost when you don't, thereby allowng less wear and tear on your vehicle. I believe that alot of the guys run this setup. Cory from tunerfixx was the fellow who I bought it from, good investment, and good guy. He knows the B6T motor and has good input on this forum!
