I'm on stock diff. I ran the IS350 Diff for a little while NA, but never with the supercharger. You'll be well into 7th Gear at the end with the 350 Diff, which Idk if it's a good idea or not. I'm pretty sure I hit at least 140 with that diff before though, so it'll probably be fine.

Yea, there's gotta be something. I've been wondering myself. I can always try the IS350 or GS Diff I guess. The IS350 Diff helped a lot NA, but idk how it would do supercharged.

Did you hit 140 with the same DR setup?

No, I did it on street tires, but shouldn't make a difference. Tire speed would be the same at the track, I was more worried about driveshaft and trans speed, but I think it'll be ok. I may try the GS diff, it's like 3.77 a little less extreme than the 4.08 and I think I might be able to finish in 6th.
