Just pointing out that perhaps previous pads may feel different on this car. It may be worth it.
There is more than just the pads to the feel. A big part of the feel would be the brake lines. Once you get some heat into the brakes, then its onto the fluid, and boiling the fluid.
The HPS are a good street pad. Light duty. Nice cold bite. Good for drag race guys, street car guys. Doesn't handle a ton of heat. Hawk has a HPP that is more aggressive(100F-800F). From there you can go up to a brake pad that will handle more heat like a DTC 30(100-1200F) , 60(400-1600F), or 70(400-1600F).
When you install new brake pads you also need to make sure you follow a proper bedding procedure. If you don't bed them correctly, you can glaze the pads, and you will not have good braking performance.
