Picture for representational purposes only. Actual product may vary slightly.EBC Racing 2021 BMW M3/M4 (G80/G82), M5/M8 (F9X) RP-X Race Front Brake Pads
- RP-X™ also boasts a flat friction response and is capable of operating at temperatures of up to 8500C without brake fade, yet has a slightly higher average friction of 0.55mu. RP-X™’s higher friction level provides a stronger initial bite and more power under braking, all for a reduced pedal effort compared to RP-1™.
-
If you’ve experienced some of the leading track/race compounds from EBC’s competitors (such as Pagid RS29, Ferodo DS 1.11 or Endless ME20) then RP-X™ will feel very similar in its response characteristic. The higher friction level and higher initial bite mean RP-X™ is well suited to under-servo’d vehicles (for example: R35 Nissan GT-R and Porsche GT models).
-
On these inherently under-servo’d vehicles the brake system is naturally more progressive and feelsome, therefore a more aggressive pad material such as RP-X™ is preferable to keep pedal travel within the optimum displacement range. However, the extra power served up by RP-X™ isn’t at the expense of exceptional feel during the braking phase, with the material still allowing the driver to modulate the brake pedal with ease and explore the limits in each and every braking zone.
-
Similarly, dedicated track/race cars that employ aftermarket master cylinders, sway bars and bias adjusters would also be well suited to running RP-X™, since these components allow the driver to fine tune the brake bias to permit the use of a naturally more aggressive pad material.

The perfect sock!
Size: 6-10, Color: Halo Gray/Assorted
The only socks that I can wear with my hey dudes. They stay on my ankles and never slid down into the shoe. I will forever order these as long as they are available. They are comfy too!

Good option, especially in warmer weather
Size: 6-10, Color: Black
High quality socks and very durable. Nice touch adding the grip on the back of the ankle so the sock stays up. Size is a true fit to the size of your foot as well.

Love these socks!
Size: 6-10, Color: White
Comfortable, no show, and most importantly The Do No Slip!!!! I keep coming back to add to my supply because they have become the only sock I wear. I’ve been using them for a couple years now and they hold to great to washing, bleaching and the dryer. Highly recommended.

The only socks I will buy
Size: 6-10, Color: Halo Gray/Assorted
These are hands down my favorite socks to wear with tennis shoes. Bought my original 6 pack in the store, liked them so much I went buy more and they were gone. These don't slip on your heel like most socks do. Come up high enough on the top of your foot to protect from tongue rubbing (I giggled when I wrote that) and they come in fun colors. Love they are ultra no show and provide padding but people can't see them with shoes on. Five stars!
