    So after some facebook/old forum research, it appears that the 99+ stock rocker is a 1.66 vs the 96-98 being 1.6. I'm not finding a ton of evidence but there is some info here and there. Nothing 100% though. Does anyone here have any info?
    98' GP coupe NIC Pacesetters, E85, FSIC, 2.6, heads, blah
    11.82 @ 118.4 with a 1.8 60ft
    Retired: 99' Regal GS Turbo 11.428 @ 122.61 1.7 60ft.
    Retired: 99 GTP top swap nic setup. 13.37@106

    I'm not convinced there is any difference. It would be interesting to measure an older rocker vs a newer one to actually see.

    That's kind of where I'm at with it. I have a 98 and I've got a set of 04 rockers in the garage.

    I highly doubt there is a difference. However it has been noticed that it depends on where you measure. As the rocker tip is pushed down, you are using more of the edge vs the middle and that's where I believe the difference is found.
    I drink..so consider that when reading my posts.

    Check the part numbers and see if there was a change.

    I may have a spare set of rockers from a 97 I can compare them to. I'll report back here with my findings
