Dear alfaizal,1. I am a customer of Ultimate and have always found their charges to be reasonable.2. You mentioned that you are using 17" wheels. Are these BM originals or some aftermarket rims? Some aftermarket wheels has a larger centre bore and therefore adding a hub centric ring is required.3. Ultimate also does wheel alignment and balancing.4. Since you have replaced those bushes, my suspision is that you need "on-wheel" balancing. Try doing this first to see if it eliminates your vibration problem.
