This post will serve as a continually updated place where I discuss my current (public) modifications list. From time to time I’m under NDA for certain parts, so they may not be reflected. Overall, this should be current. Broken down into engine, drivetrain, suspension, and safety sections.

Additional Equipment

Other Information
– I run Carbotech 1521 pads on the street – and for light duty events such as Track Night in America, I typically stick with the 1521’s on the rear while only changing the front.
– The MXm pulls from the CanBus for the power train.
– I’ve got an exhaust valve controller installed so that I can do quiet early morning startups.
– I use spring rubbers to fine tune the rates of my springs. While towing, I use a set of hard rubbers in the rear to re-enforce the rear suspension. These are simple to install/remove, and they are legal for Tuner 2 (as of 2020 rules for SCCA)
– My front brake ‘scoops’ have been extended down by about 2 inches, which has *greatly* improved airflow on higher speed tracks.
Next Steps:
– JXB Spherical kit (Soon!)
– Front Aero (Soon!)
– Unitronic Stage 2 OLOA tune (Soon!)
– Rear Aero (with a spare damaged trunk lid that I have, Timing TBD)
– Custom built half-cage (2021/2022 off season project)

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?
