Did anyone using hub centric ring on aftermarket wheels?

I see, managed to get my problem fixed.

The center cone is essential to aftermarket wheel, because before when I replaced my wheel, I didn't use it so I got steering vibration when I drive it about 100km/h.

With center cone, it was smooth all the way and had lesser noise also when slow driving. Damage was RM80 include installation, advice not to skip it.

Is there any ultra racing owner here? I wanna ask does the ultra racing bar help on lowered down the cabin vibration or noise on idle?

Ouch, then I probably should stick back for more soundproofing, and take note on the mounting parts. Because light sound proofing is difficult to address the low frequency or engine vibrations that conducted or amplified in the cabin.
