Thanks for keeping this updated. My '19 Sportwagen is set up pretty similarly and I can't believe I never commented on this thread. is38, IE downpipe, MST intake, Golf R springs, Koni SAs, Golf R rear bar. I have a 6MT with an Audi TTRS clutch. My brake 'upgrade' was the 312mm rotors that are stock on the AllTrack. I just love the car - maybe because it's so good despite being so cheap ($22,300 OTD + $6kish in parts).
I'm at 60k miles and the only problems have been the ubiquitous thermostat housing leak (to my great shame, I recently paid someone to swap it because my 360 is stuck on the lift) and a bad balljoint. I have done nothing else but fluid changes and one set of plugs since the modifications at 7k miles.
I've been wondering what kind of lifespan to expect from this thing, given it's nearly 2X HP increase. Your results give me hope.

In reply to mfennell :
Glad to hear the thread's been helpful! Your build thread was actually what started me down this rabbit hole in the first place, and I'm glad to see yours is still holding up so well.
To your point, I can't think of many other vehicles that deliver the mix of performance, practicality, and comfort that these cars do at the price point. Really, my only gripe is that it's so competent, it's almost boring. Even with the (likely) mechatronics failure that mine just experienced, I still love the car and am looking forward to getting it back on the road. Just wishing I had a 6mt car at the moment lol
I need to get on getting an IS38 installed on mine now. Been stalling because of having to do the clutch at the same time.
I got the Golf R Estate suspension with the Koni SA's installed on mine over the weekend. Just need to get the ECS's installed on the OZ wheels and my diesel geek short shifter. I'll post some pictures but this has been a great thread to get ideas too.

Back in action*! And on the summer wheels now
Replacing the mech unit fixed it. Life's been wild, so I had the shop take care of it. The bill made me miss the days of DD'ing a manual ALH, but driving the car again made me remember why I put up with this stuff sometimes. Jon showed me that the cannon plug had cracked on the old mech, allowing fluid to get into the connection and short out the speed sensor. After installing the new mech and doing a DSG service, Jon had to bring the car to the local VW dealership to unlock it, since these have Component Protection. Maybe one day there will be a cracked version of ODIS, similar to VCDS. I can dream at least.
*The car still can't really be driven since the new TCU doesn't have the DSG tune applied to it. Don't wanna toast my clutches after all of this. I've got an appointment with the local APR dealer on Tuesday for this.
