GT12 Atom Rear Q Foam 35Sh - 48mm

Q foam offers more performance than A foam in most conditions. It does however have higher wear rates so needs to be replaced slightly more often than A. It works great on ETS type carpet. Compared with T foam it is capable of matching T foams performance on lap time, although it has a tendency to lose some of its performance throughout the race when using all non-oil type additives such as SXT3.0 or Nosram Carpet.
