Well, they are lug centric, they came with the plastic centering rings. I jacked the car up today, and took the rims off, made sure the centering rings were secure and actually there smile Got to check everything. Double checked that the retaining clips were indeed removed, and they were. Put the wheels back on, torqued them down in the air to 100, and made sure the air pressure was at 32 psi. And the shake has gone down a considerable amout, still there but this time, only very prominent at around 75+. The funny thing is, it comes and goes, starts for a few minutes, goes off for a few minutes, and over and over again. But again, not close to what it was. Should I be torquing them down less/more. More or less air pressure. Or get them balanced again. Any ideas. Thanks.
