Vibration Problem

I would try to find a place that can spin balance the wheels on the car.Sounds like the new brakes are out of balance.
Good luck

Before you have the wheels balanced I’d check that the wheels are turning true (no wobble). They may not have the top hats on the rotors seated correctly. The other thing to check is that Panteras use hub centric wheels. Depending on the top hats used the hub may not be mating to the wheel correctly. Also some kits come with a couple of speed nuts that go over the wheel studs to hold the top hat. These can misalign the wheel. I assume the vibration is not just under braking.

Hopefully you had a Pantera vendor install the brakes and you can just take the car back to them. On the other hand if it was a Pantera vendor they should have done a test drive before returning the car to you.

Thanks for the information!

This could be something minor to an absolute catastrophe waiting to happen.

Depending on how the brake upgrade is set up (external hats?) it could be a number of things; stud shoulders not allowing wheel seating, hats, calipers etc. If the rotors were replaced all round then the rear hubs came apart, could be just the half shafts or something far more serious.

Please, please get the car transported straight back to the brake upgrade installer for a thorough inspection and correction.

Thanks again. But the shop I brought my car to caused this problem. I need to find a shop in the Tampa FL area that I can trust
