Who Is Tracking Their S550 GT500? I'm Looking For Someone Fast & Knows The Mods Inside And Out

Myself and my track buddy have run ours hard for 4 years on track with the normal DCT factory fill level. I checked mine in year 2 to see if it was underfilled from the factory and it was good. GM has so many DCT procedures partly because it shares fluid with the rear diff in that transaxle. They require more frequent fluid changes, overfill etc. By the manual the GT500 needs nothing, just run it. I will filter/fluid mine this year probably, but it has over 10k of almost all track miles and still works great.

Best thing you can do is go to the best brake fluid you can find. The gain there is less frequent bleeding required - I use AP R4 - do small bleeds every 5 track days or so. Stock pads work great, buit will start to fade when they get thin. You can replace them cheap from rock auto, and turn the rotors 2-3 times easily as they get worn.

Several guys on GT500 board that have tracked upwards of once a month since new (20/21), and this is the first I've heard of over filling.
Always up for new info, but not overfilling does not seem to have any detriment.
