My 16's still rub
 

For those who have asked about tire rub issues with 16's..... Well, I have a set of 245/45/16's on the rear of an 84 gsl and as you might expect, they rub. The stock springs looked pretty bad so I decided today to swap them with a pair of RB springs that I had. The bad news is, they still rub. In fact, they are worse than before. They dont hit as hard but they hit more often, if that makes sense. They rub on smaller bumps that they didnt rub on before. Just wanted to let you know what the outcome was for me in case someone is planning on trying it themselves.

You have 8" wide back wheels? That would do it.
