Track pads might not be great on a road car. They are often very hard and need to get up to temperature before they work .. so an emergency stop on a cold morning soon after leaving home might require a change on underwear.
I fitted Ferodo Performance pads to my 156 and along with braided hoses and Castrol Performance brake fluid transformed the stopping power .. to think I'd put up with "adequate" for over 12 years!!
I later fitted MTech drilled discs which made a difference on long downhill braking as they didn't overheat.
