Renault Sport déconseille les disques rainurés si l'on met autre chose que de l'origine.
Il préconise expressement les disques pleins pour les les FERODO DS2.11.
Personnellement, j'ai "gondolé" un disque rainuré avec des PFC Z Rated, en principe plus tendres que les 97. Avec les disques pleins, beaucoup moins de problèmes.
J'ai trouvé en anglais les caractéristiques des différents composants des PFC. Du plus dur au moins dur :
07 compound PFC’s latest high bite and torque compound has been designed for the GT and rally market and has gained immediate favour with factory teams due to its unsurpassed performance. 07 has higher initial bite and higher average torque than any other PFC compound. 07 will have some friction rise with temperature and handle the most severe applications. The release and modulation characteristics are excellent as this compound is favoured for both tarmac and gravel surfaces. 07 gives very low disc wear despite its considerable performance and is still capable of similar wear to 01.
05 compound has higher initial bite with higher average torque than 01 compound and virtually no friction rise with temperature. 05 has excellent release and modulation characteristics and recommended for high grip, high downforce and severe duty applications. This compound demands the most from the vehicle setup and is suitable for tarmac applications.
01 compound has high initial bite and torque with very little torque rise with temperature.
It has less torque scatter at the end of the stop for improved modulation. 01 Compound has good disc conditioning properties with low wear.
01 Compound is one of PFC’s most popular race compounds, and wins more World and National Championships annually than any other brake pad on the market. Recommended for a wide range of competition applications, both tarmac and gravel surfaces.
06 compound has been designed as an endurance / sprint compound and is very similar to PFC 01 for both bite and torque, with excellent release and control with very low wear and very easy on brake discs. 06 pads are an excellent alternative to other brands of endurance compounds but give a much higher performance. This compound works well in both motorsport and OE type calipers even when ABS systems are retained.
08 compound is one of PFC’s newest and has gained immediate favour in extended Endurance Sportscar, and GT racing due to its performance in applications where smooth initial bite is a must. 08 has a slight friction rise with temperature, excellent release and modulation characteristics. Very low disc wear, similar to 01. Despite its considerable performance, 08 has the lowest wear rate of all PFC compounds and can easily match the wear characteristics of the other competitor’s materials but with much higher bite.
97 compound has less initial bite and average torque than 08. It has great modulation, a very flat torque curve, and enhanced release characteristics. 97 is recommended as a generalpurpose pad for Club Racing and Track Day events. This compound also works well in the rear when a higher torque front pad is chosen but a very stable consistent low torque rear pad is required. 97 compound can produce higher levels of dust at elevated temperatures.
Z-Rated .10/.11 - This compound has been designed for fast road / trackday applications. It gives more stopping power and increased fade resistance over the OE materials but retains the good qualities or the road pad i.e., low dusting and noise along with low wear rate.
• High performance compound, gained through competition pad developments
• Compound designed for low dusting qualities
• Several built in noise suppression technologies
• Excellent disc conditioning, giving even transfer layer on disc to reduce uneven pad deposits.

Pour information, voici ce que pense des FERODO DS2.11 (achetées chez Renault Sport - Référence Renault Sport : 7711163979) un ami du forum qui participe aux JPRS en M3RS Trophy - groupe noir :
"les FERODO DS2.11, c'est mon deuxième jeu.
Avec j'ai fait une longue journée d'entrainement libre à Folembray et la JPRS du Castellet en 2012 ainsi qu'une session au Mans 2013.
J'ai mis un nouveau jeu au Mans et je vais les utiliser à Spa.
Je ne les ai pas ménagées et je pense que vous connaissez ma manière "assez tardive" de freiner. Je pense qu'il est possible de faire 3 circuits avec.
Certes elles sont chères (~360€) mais je les trouve plus efficaces et constantes que l'origine, un excellent feeling qui procure une assurance dans les freinages appuyés.
Concernant les UNO, je ne connais pas leur efficacité.
Mais vu le niveau de prix des UNO et l'écart avec les DS2.11 d'origine RST, je n'engagerai pas 300€ pour essayer.
Pour moi pour la M3RS, il y a deux valeurs sures : l'origine RENAUT et les DS2.11 préconisées par RST (Laurent HURGON a participé a la validation de cette référence)."
