I’m looking for a pad that can handle everything from commuting during the week to “spirited” canyon runs and a few casual track days just for fun. Since my main track vehicle is an S2000, the goal is to find a pad that works well enough to avoid having to swap pads for the few track days the car will see during the year. The problem is that the car doesn’t see enough track time to warrant running track pads full time, as they will trash the rotors faster than I really want. Plus, potentially noisy track pad aren’t what you want on the car if you’re taking your wife, girlfriend, boss or others out in your car. This leads me to stay with an aggressive street pad or “hybrid” pad (Ferodo DS2500 is probably the most recognized in the category), but there are very few hybrid compounds that have the potential of handling a good driver using the stock calipers on a racetrack.
About Endless MX72
Endless MX72 was one of the first compounds that came to mind when thinking of the best pad for this type of use. It is one of the most versatile compounds- essentially being a street pad that possesses some race pad characteristics. The description from Endless reads, “Ceramic is known to be one of the most vital and essential compounds which influence braking capacity. Every material has been carefully chosen for the MX72 in order to produce minimal noise and dust while producing high brake capacity during lower temperatures. Braking stability was also improved under higher temperatures while decreasing rotor wear. Pedal feel, which is typically great in semi-metallic material pads, was further improved upon.” Perhaps the best way to think of the Endless MX72 is a better Ferodo DS2500.
On paper the MX72 compound shakes down like this:
Usable temperature range 0-700*C (~1,300*F… Roughly the same MOT as Pagid RS29 endurance race pad!)
Coefficient of friction ratings vary from manufacture to manufacture since there is no universal, consistent way to test but Endless publishes .37-.47 through its temp range, which is plenty even for aggressive street tires. This is very impressive for a street pad- Figure the average OEM pad has an MOT of roughly 700*F and a coefficient of friction around .35, that number drops dramatically when the pad is operating in the higher end of its temperature range.
Who would benefit from Endless MX72?
-Anyone who daily drives their car, tracks a few times per year and doesn’t want to swap pads for track days or have the drawbacks of track pads on the street
-Anyone who thinks they might take the car to the track but doesn’t know if their current street pads would be up to the challenge.
-Anyone who simply enjoys driving more aggressively on the street, on twisty canyon/mountain roads for example.
-Anyone who is picky about the characteristics of their pads (strong but smooth initial bite, good midrange torque, modulation, release and pedal feel/feedback).
-Anyone simply looking for a more aggressive pad that will still be civilized on the street and work flawlessly in the cold.
Possible group buy
I looked into them more and talked to the director of Speed Freaks, LLC to see if it would be possible to get them in the pad shapes Audi uses on the B8 S4. The good news is they can have them made but the bad news is they aren't exactly cheap. I guess you have to pay to play. I was thinking about doing a group buy since they are phenomenal pads and it would be a great way to get the price down a bit but I’m not sure how many people would be interested. For those interested- list price on the pads is $370 per axle set, so $740 for the complete set plus shipping, taxes ect. Depending on how many people would want in we could get that down to roughly $650 or so shipped, maybe less.
If you guys don't know much about Endless, they are a top tier pad manufacture who makes some of the best pads from super low dust street pads to some of the best sprint and endurance race pads known to man. Endless makes products that are used in pretty much every form of professional motorsport from WRC all the way to F1. They are starting to gain more popularity with European cars now that they are making their compounds more available. I know that in 2011 the top 5 cars that placed in the 24 hours of Nurburgring were using Endless ES88G and by 2013 40 cars were using Endless ES88G and ES99G over Pagid RS29 and PFC 08.
I think its worth mentioning that these are the go-to pads for many Nissan GT-R owners, which says a lot since those cars are so brutal on brakes. I think its also relevant since they are similar to the A4/S4 and A5/S5 in that they are heavy, fast vehicles that demand great pads and the owners tend to be more picky about noise and dust from street pads. I think if a few Audi owners gave them a shot they would gain popularity quickly.
Since this is more of a feeler thread please post up if you would be interested. Im placing an order in a week or so regardless if anyone else is interested or not, just wanted to present an opportunity for everyone to get a better price
Thanks.
