Love your articles and appreciate your improvements. Have done much the same mods to my 2015 S3. Pretty much everything from 034 Motorsports. Installing the Wavetrac over next few weeks – did you have make any adjustments via OBD11 or VCDS?

Hey Scott! Thanks for the comment and feedback!
Take a look at the XDS settings. With the front wavetrac you’ll likely want “weak” or “off” so that it doesn’t righty against the built in traction control. You’ll need to play between weak or off depending on how well your car rotates. Good luck!

Hey Rob! I see you have Girodisc rotors and an awesome pic of them glowing in a turn. I just got 034 rotors, and after 3 track days managed to crack both of them. Have you ever had this issue w/the Girodiscs?

Hey AJ, unfortunately I’ve been starting to hear that the metal that 034 used simply cannot withstand the track use that we are throwing at it.
I’ve certainly cracked girodisc, but it took 18 days of extremely hard use before they even started to show signs of cracking, and the cracks were not “all the way” just to the edge (which is close enough for me!)
For a “normal” track user, I would expect 25-30 days of track use before a replacement of rings is necessary.
What pads are you currently using?
