Would you recommend E or D compound (for Dynalite calipers) for a daily driven SRT-4 that goes to a track day once a month? Or should I stick with the Q pads and just switch to E or D before hitting the track?
The D pad is a great Auto-x pad. Same pad I run in the Pikes Peak car. For cold rotor temps. But I can fade them a bit with too much left foot or turning brake. Excellent for 'right now' braking.
The E pads are the superior pad for modest track use. The upper temp range is better than D and the response is not too bad cold. Better than D for sustained temps.
The BP10 is the newer pad. It is supposed to be the more middle ground and less problematic as Q. (I no longer use Q as I've had way many complaints) Personally I don't feel the BP10 is quite up to the task of either the above pads.
If you're happy with Q and simply need some modest open track parts; E.
If you're happy with Q and simply need some more bite/drags/auto-x; D.
