Read my post from 5/1/2023. Tried everything vibration would not go away. The stock (I said stock) Z suspension control arms with rubber bushing were designed for max 28lbs -30lbs tire air pressure on narrow tires. You're probably running a wider tire with a manufacturer suggested air pressure of 32lbs or 36lbs.
I don't race but have been told most car drivers will reduce air pressure on the track. So just reduce your air pressure to 24lbs in the fronts and 24lbs in the rear and see if the vibration goes away. If so, begin to add pressure 2lbs at a time to find the tipping point with the tire pressure / suspension and the vibration.
I'm running 25lbs fronts and 26lbs in rears on the street (15 60 205), no vibration. Is the car harder to steer at low speeds, yes but the steering wheel is much more enjoyable at driving speeds.
Took it a step further and had the wheels (rim), tire, hub and rotor dynamically balanced (single wheel dyno) on the car. Downside, wheel must remain in the same position on the car, mark on the hub and no rotation.
Good luck.
