What brake pad compound is used? Carbon fiber metallic
How much dust do the brake pads create? Medium high dusting
What's the difference between track day and track day spec? Track day spec is designed for strict track duty and not recommended for the street. Regular track day can be used for both but doesn’t have quite the same bite that Spec pads offer.
How hard are they to install? Varies by application, but removal of calipers is required. Having a caliper piston compressing tool is very helpful. Remove some fluid from your brake fluid reservoir to prevent overflowing. Fresh fluid and flush is recommended.
Are they loud, or do they produce noise? Noise when cold is not uncommon given the nature of the higher coefficient of friction found in these track pads. Once up to temp, they are typically quiet.
