    I assume this is off the gas? Take some compression out of your rr shock.

        Can you drop the gas pressure some? If not, I know it sounds backwards, but what happens if you lower the j bar a half or 3/4" on frame? It may actually help the car roll a bit.

            Those cars typically struggle with a tight in the center condition and judging by your description of tire wear it sounds like you may be slinging the car a bit on entry and over working the RR tire.

            How is the car on entry? Is this a track where you enter on the fuel?

              "Those cars typically struggle with a tight in the center condition"

              Sooo very true.... running the rear end to the right of the Current Rocket recommended baseline will help this known problem.

                Have you kept an eye on RF shock travel? And is the engine just up 1/2" or is it up and to the right? The suggestions given are good advice, but from personal experience with an 04 black front car, with a heavier engine we had bottoming out problems on the RF. Make sure you are running a 12" spring too because a 10" will coil bind. If it bottoms out or coil binds it will cause a loose in center condition. So it might be something to take a look at.

                Later,

                    No one thinks the LS weight is to high?

                      No sir. I think most people don't run enough.

                        I have a hunch your too tight on entry.
