Hello everyone. Let me start by saying I got my 2016 Camaro SS a couple years ago, and this site has been a valuable resource for me for all things camaro related so thanks to everyone who contributes. This is the first time I have posted. My car is a bone stock SS manual. I have done many street pulls in Mexico and never experienced anything like what happened this past weekend at the track. So first I get there and air my rear tires down to 26 psi. They are BF Goodrich Sport Comp 2 AS. I know these are not the best tires, but its my daily year round so all seasons are the most practical for me. They work well enough for my HP level on the street. Anyway, I air them down, double tap the TC to go into competitive mode, drive around the water box, and stage. I was worried about potentially snapping an axle and not having car to get to work the next day so I left pretty conservatively. The car dead hooks and bogged so I'm able to mat the gas. The prep seemed pretty good and the car is hooked and pulling, but not as hard as it does on the street surprisingly. I get about 60 feet out mid way through 1st gear and the car violently starts shaking and there is a loud thunk thunk thunk sound coming from the rear of the car. I felt like it was coming from the diff/driveshaft/cradle area. I mean violent to the point I thought I broke something and got out of it. Once I realized it was ok I got back in it and it starts again. I made several more passes experimenting with every drive mode/traction control setting combination and all were the same way. Even put air back in the tires. Hooks, then shakes hard 60 feet out and pretty much the rest of the way down the 1/8 mile. It doesn't even feel like it's spinning to me to be honest. Just makes that loud thunking sound, shakes, and pulls power/stutters. By the way, I get the same thunk sound every time I no lift shift, but only once each time I release the clutch. Not repeatedly and never mid pull in a gear. Its always done thos and I assumed that was normal. I have a dragy device and my times on the track were WAY slower then I have ever had on the street even on the worst of roads. Car feels like its down 70 hp. You can see from the dragy pictures that it is significantly slower and these pulls were on the same day. Look at the acceleration G. The faster one is on the street. My questions are this:

1) Would wheel hop happen down track at stock power levels?

2) Would a more grippy bias ply drag tire make the situation better or worse since this has never happened with street levels of grip?

3) If it is wheel hop, does the car's ecu have some sort of wheel hop protection and pull power or does torque management intervene even with all nannies off?
