The Dynalite is not currently used on any FM brake kits, but it was the mainstay of the NA/NB kits for years. It's also quite popular with other vendors.
Kits since early 2014 have used the Dynapro caliper . They're easy to tell apart, the Dynapro has a big W shaped pin retaining the pads while the Dynalite has a single pin in the middle. Please look at the diagram of the pad design to ensure you are buying the correct pads.
If you would like a pad from a different pad manufacturer, ask for Wilwood plate 7112 for the four piston.
We have several brake pad options available for this caliper.
The BP-10 is a street compound. It's quiet and doesn't dust much and is fairly consistent through the temperature range. It is a medium friction pad with smooth engagement and a low to medium wear rate. As it gets hot, it will wear more quickly. This is the standard pad for Dynapro applications.
The BP-20X is the newest compound here. It's quiet enough for street use but will hold up well to track use. There's a chance of some squeaking with light street use, but it's the closest thing we've seen to a pad that can do everything.
The BP-40 is a track pad. It's what we use on our V8 track cars. High friction even when cold, nice smooth response, and good wear characteristics.
