Thanks again for the ride last weekend! Really enjoyed it!

I can tell you guys, and Brembo will also tell you, this car is fast! 3rd gear was fast enough for me lol. The twisty norwegian roads also add up to it

You almost forget to breath under full acceleration...

Saadie · « **Reply #7 on:** 15-Sep-2009, 13:45:50 »

^ ohh so thats the story behind the 3rd gear story in the other tread

Thamar · « **Reply #8 on:** 15-Sep-2009, 17:30:43 »

To bad we didn't have more racefuel. (and a inboard camera

) You must take a trip back to norway when we have trackday in the vw-audi club.
But you didn't "brake" so hard in the passenger seat that the vacum hose to the ecu did fall of. Some do that you see.. (Brembo ?)
