Type R pistons, for people who support animal cruelty.
but they really aren't the best for you.. Why? because we don't know your budget or goals.. Do you even have a way to tune this.
We can recommend them, but if you are looking at all out N/A the higher the piston compression the better off you are(to a point) as long as you can run the right octane fuel, have it tuned and have the appropriate headwork and bottom end work done to support the revs necessary.
