Clutch slipping or srm?
 

Got a little issue guys. My car is having trouble shifting at the track, especially from 2nd to 3rd. When I hit redline at 2nd, the car doesnt always fully engage into 3rd. You can see the rpm stay up for a sec or I have to do a quick lift to get 3rd to re-engage. I get the same problem from 3 to 4 from time to time too. I just want to see if this is a srm issue or my clutch is going or could it be hydraulics? Thanks. I have 29k miles

i would doubt it is SRM most likely a clutch disc or hydraulics issue. i would bet on a contaiminated, burned or worn disc if it is getting worse

try doing a clutch fluid change if its really black that could be your issue.

I always complain about the stock flywheel being too heavy, I feel like I am waiting forever between upshifts.

It's not SRM. Is ur clutch adjusted to FSM spec? Fluid nice and clean?
Mods of the drivetrain?
