Kyle's B8 S4 Build List
When I first started college, I remember seeing for the first time a B8 S4. I just stared at it and thought to myself "what do I have to do to own one of these?" Then i had the the pleasure of going to lunch with one of my professors who just happened to have a v10 s6. I was instantly in love with the car. So here we are years later and I now own both a b8 s4 and a c6 s6. May not be the smartest life decision to own two "S" cars, but my drives are never boring about two years ago, I was browsing b8 s4s. I had one on my watch list that was dropped in price. However, it was about 10 hours away in the middle of Virginia. I made a call, went down the next day and traded in my Jetta TDi for the S4.
As for my Audi S6, I was able to find one local to me that was a one owner car and pretty well taken care of. The previous owner had already installed a Milltek exhaust which makes the v10 absolutely scream. The torque the car provides in combination with the sound is just an amazing experience. As far as modding it, I only plan on getting some wheels for it. So far it has he lightweight crank pulley from JHM, EBs red stuff pads and upgraded plugs and coils from NGK. At some point the car may get lowered but that is a ways off
