30/19 means front is 30mm and rear is 19 mm

I always wanted to say that, lol

Nope.... SS's, 1LE's (all but '93's) and WS6's have 32/19's. Only '93 1LE's had 32/21's stock and that's because they kept the stock rear springs and upped the front rates. Later year 1LE's upped the rear spring rates and kept the standard rear bar instead.

My bad. Sorry. I knew the front was 32 though. And I knew the rears on regular Z28s and Trans Ams was 19. Didn't realize it was that way on the WS6s and SSs. My mistake. You should go 35/22 anyway

Not a problem. Most folks think that, then if kind of just spreads (probably how you figured it).

Yes, Like I said, 30/19 is the answer to the original question.

SS just upgrade the front sway to 32mm like Strano said.
