Did the people making recommendations to you about brake pads know what you meant? Looks like you bought a pad that is intended to be a good compromise between lighter track use and street use, that is not suggested by the manufacturer for street use. You are likely getting high heat tolerance you don't need in exchange for poorer cold behavior.
For autocross use, you want a feel and friction coefficient you like, and you want that to be consistent from room temp up to something above what is generated in a highway panic stop.
Track use is totally different. At a race track, high heat tolerance is critical, and wear/friction coefficient when cold is almost irrelevant. That highway panic stop temperature is where the graph starts for grip vs temperature. Some track pads give decent braking cold, but via an abrasion mode which is murderous to rotors (which doesn't matter because the brakes work cold, and cold application is infrequent). Some just don't really work cold, or give horrible feedback/feel while warming up. Most have very steep friction vs temperature curves at low temps in exchange for consistent and higher fade limits and/or progressive fade.
An excellent street pad is always a decent autocross pad. An excellent autocross pad is usually a decent street pad. Any pad that is a good or better track pad is going to be a lousy autocross pad (at least on a powerful car). Most excellent track pads make downright horrible/dangerous street/autocross pads.
