I have the TA relocation bracket and have it set around where it was in the stock position. I have no idea what the pinion angle is right now. Which hole position will give a -2 pinion angle? Thanks

 

The holes are slotted to allow adjustment to set the proper pinion angle. You need to use an angle finder (available at Home Depot or Sears) to determine your pinion angle. It's the difference in angles of your transmission relative to you pinion gear. Here's a good read: http://buickperformance.com/Pinion.htm

 

does TA relocators make your camaro's cab noisier?

 

Yes.
