Silver S2k4

My car is lowered and supercharged and I am on my 2nd diff and now there is a very hard banging sound and feel when I press the gas. I am guessing my driveshaft or diff is goin up.

I want to replace everything but also get spacers when I do to make sure nothing breaks again. Theres driveshaft spacers (trans to diff) and axle spacers, (diff to axle).

Would I need both? Which does the most?

There are different applications for race and street use, anyone know the difference?

Thanks for the feedback.

If you have an AP2, you don't need it.
