Benefits of  the Carbotech ceramic - Kevlar based brake pad

• Much lower dusting than comparable carbon-metallic pads. What dust they do make is very light colored and not as destructive to your wheel's finish.
• The frequency that the ceramic material vibrates at is beyond the range of human hearing so you will notice relatively lower noise with even the most aggressive Carbotech race compounds.
• The slight compressibilty of the Kevlar material gives Carbotech's their legendary modulation and release characteristics. No on/off switch!
• Using Kevlar instead of steel strings makes a stronger pad, able to withstand greater abuse
• Ceramic gives the flat torque curve these pads are known for. Note the very small difference between cold and hot friction levels in the chart
• Ceramic gives equal friction to a carbon iron based pad but much less rotor wear. Carbon and iron when heated creates carbide, what cutting tools are made of!

Choosing the right compound

The 1521 compound is direct OE replacement pad yet offers better bite and a higher maximum operating temperature.

With ABS  we recommend using the same compound front and rear.

Without ABS If you do not have ABS, you can use a lower friction rear pad to improve brake balance for competition use. Mixing compounds is not neccesary for the street.

 You ideally want your fronts to lock just before your rears on smooth pavement in a straight line. The AX6 can be used for the track but only on lighter, llower powered cars with intermediate level drivers. If you are above 2600# total with driver and above 150whp or and advanced driver, you will probably be happier with at least XP8's in the front. For reference, the fastest Spec Miata's use XP10's in front and XP8's in rear.

If you wish to switch your XP pads out for trackdays, AX6's should be your street pad. The 1521 transfer layer is not compatible with Xp series pads.

Compound guide

READ THIS!

Carbotech brakes require their own, uncontaminated transfer layer made by Carbotech pads or a similar ceramic-kevlar compound like the dealer installed OE Akebono's. If this is not done, you will not experience the full potential of the ceramic-kevlar compound.

You will need to do one of the following:

• Resurface your old rotors
• Completely remove the old transfer layer with a steel wire brush/flapper disc on a drill/grinder
• New rotors
