Technical Information
The Enduro kit uses the 9668 variant of the Radi-CAL Pro5000R caliper. It uses the pad shape #CP3558D54 with an increased thickness of 25mm for prolonged durability.
As a result, the caliper is 0.7 lbs heavier and the kit is slightly more expensive.
All kits included tension pads that replace the original AP Racing pad clips.
They are designed and machined to greatly reduced pad movement within the caliper, thus reducing vibrations.
The kits can be optionally spec'ed with Ferodo Racing pads at a bundled, discounted price.
The DS2500 is the ideal dual-duty pad compounds, with the DS1.1 stepping into race pad territory, increasing in friction and durability as you go up to a DS3.12.
In this Special Series, I will document the unboxing, fitment, first impressions and long term review of the AP Racing Competition brake kit on my E46 M3, and a local E92 M3 Clubsport build.
Enjoy,

Been there, done that.
AP Racing’s very first grand prix win with brakes and clutches was the Ferrari 312B driven by Mario Andretti in the South African GP at Kyalami in March.
It wasn't until 1989 that AP Racing developed its first OEM road car brakes for the Lotus Carlton.
AP's presence in BMW M cars is new relative to the company's existence - yet its innovative designs starting with the RadiCal family of calipers, followed by the race derived 5000R have carved a reputation as the benchmark in the market.
I personally run AP on both M3s to great effects, with vastly different kits.
