AP Racing policy is to use the best materials available.
Two alternative materials are currently offered:-
- Heavy Duty = S3 Material has a good wear rate and high strength and impact resistance. It is particularly suitable for very high speed engines (over 12 000 rpm) such as F1.
- Standard Duty = S1 Material has an exceptionally low wear rate and a lower cost than 02 material, but has a lower strength. This material is the usual choice for all lower speed engines (under 10 000 rpm).
AP Racing can advise on the most suitable Carbon / Carbon material required. This will normally be dependant on application.
