Using

12.16 at 110.66 mph. I don't think my conservative street tune will crack the 11's without installing the headers and PSRI I have in waiting so you stock block Florida guys are safe for now
If there is a wobble something is WRONG. I have run 17-18psi w/ a trap of 117mph with no wobble. I have spoken to dozens of other who run the same MT and all have reported no wobble with traps up to 130mph.
Are you using the MTT-3786R ET Street Radial 305/45R18?
IF so figure out what is wrong, bent wheel, square tire, bad track, improper mounting on hub, etc.
