What did you do to your Hellcat today?

"Balanced" does NOT mean "round"

You need both...

Hello everyone, I wanted to ask if your customized aftermarket wheels are all DOT-T certified? The set of wheels I installed doesn’t seem to have DOT-T certification, and now when driving on the highway (at around 75 mph), I experience intermittent shaking. Could it be an issue with the wheels (the ET changed from -2.5 to -5)? Or the tires (305 changed to 315)? Or maybe because of a previous impact that caused deformation in my right front wheel knuckle?

I have 2 pairs of 10.5" Factory Reproductions, I have had both over 185. Smooth as silk. But like Jimmy said, you need RFV balancing by someone who actually knows how to use the machine. Not as easy as it sounds. And quality
tires!

Were they correctly balanced on a machine with road force capabilities, and that was recently calibrated, plus operated by a competent person? If "yes" to those question, was the Smart Weight function turned off?

If even a single one was a "no", all bets are off and I would expect vibrations.

Yes, all four wheels underwent Hunter Road Force tests and the data was perfect. However, after the installation was completed, the technician noticed excessive vibration in the hub when he struck the wheel spokes with his fist.

I never go on the cheap when it comes to wheels..or tires..(on any of my vehicles..ever)

Yes, I think so too. I originally wanted the wheel style from Jimmy's profile picture on the forum, but the repair shop told me that model has been discontinued and is unavailable, so I opted for a custom one instead.
