Caliper Clearance + Tire Question

I bought my car with Wilwood brakes including 6 piston calipers on the front and they really don’t impress me in the least. My car has manual brakes but still for the money they are underwhelming. And with Wilwood brakes they have a larger hub thus limiting your wheel choices. Because of the size of my front rotors I have to run 18” wheels.A2D3EA4E-19F1-4F0C-9BCB-7BB52237FF78.jpeg
