These are amazing pads - really big upgrade in stopping power. And as others mentioned, it’s per pair. So one of each. Tdotperformance is reliable, I use it specifically for pads and rotors for not just my vt but other cars I have worked on. Great service and vehicle confirmation.
The yellow stuff pads are also Canadian winter friend. They have similar biting power to the reds but better for cold bite. Only downfall with the yellows is brake dust is fairly high. My wheels get very dirty. High maintenance for cleanliness.
