I was wondering if anyone had done much experimenting between 3 hole and 4 hole pistons. I know a lot of racers are using the 4 hole pistons now and I was wondering what the main advantages were? |

Additional question. What would the difference be between for example 4 hole and 400 oil compared to 3 hole and 350 oil? |

More or bigger holes decreases unwanted "pack" as the car drives over bumps. The car is less responsive, and the roll is easier to control. The T4 seems to work better with 4 than 3 hole pistons - the CG is lower than on previous platforms - and a softer damping therefore seems to work well, mainly for carpet. |
