I actually just got back from Costco and they told me my hub rings on the Enkei's are causing the vibrations at high speed. They said there's lots of play and they're probably the wrong size which is strange because I bought the same ones from Tire Rack that came with the set initially.
Also as a PSA, never buy Enkei's. The finish on them is complete trash. While the finish was wearing off before, I noticed a few bubbles by the centercaps when putting them back on. Just ordered some new hub rings from amazon before I decide on new ramz. I'll drop the $10 before $1200+.
The Rav just has the 2.5. Trans is kinda meh. There is some jerkiness here and there that reviewers have mentioned. The engine also sounds pretty bad but it's really just an appliance.
One thing that really triggers me for some reason is that only the drivers window lights up on the drivers door. Lock/Unlock, mirrors, and the other windows do not light up at night.
