I aren't a fan of Tarox brakes.
Or Hi-Spec/Wilwood/Bremsport etc.
You get what you pay for with brakes. They should ideally carry the name 'Brembo' or 'AP'. Full stop!
But, on topic, 4-pots are more than enough. Mine feel like the rear wheels lift off the ground if you stand on them! That's with standard drums on the rear!
