The new generation 15 compound is becoming very popular due to its excellent braking characteristics. Very good in all conditions and excellent when running at high temperatures. Its easy control and release are appreciated by engineers and drivers. Gentle on discs and low wear rate are other excellent virtues. 15 is a great compound winner in different GT3/GT4 races or open wheel categories such as US F3, F3 and Indy Lights. It has better cold bite than 11 or 13. The 15 is one of the most complete PFC compounds. 15 works very well with modern racing ABS.
