Many others as well as myself have had horrible experiences.

I thought I was immune.

IF they are NST? You've been Warned!!

Don’t buy/install NST pulley

Thanks for the update! I will look into a better made pulley.

If you not going to be doing anything serous I would just keep it stock.

I would look to check IF the alternator pulley has been also replaced they are normally a set to get the max hp from NST's combo.

If it has? You'll need to change both pulleys, And the belt IF you want to convert back to stock.

The only alternatives are Stillen which only comes with the crank pulley, And the more expensive ATI crank only pulley.

I DD the car with no track use. I can’t say for sure if I plan to SC or TT at this point in time but going back to stock would be ideal. I will check to see if the alternator pulley was also aftermarket but it just seemed to be that one pulley when glanced at. I am wondering why it was installed honestly.

AMS also does a lightweight crank pulley (stock diameter) that I've had for 10k miles now on my SC'd Z. It's made it through 2 autocross events in that time and still works fine!
