07 M8 I know stick with stock Pistons but what is better the 10up ones or stick with the 07-09 ones? Tried the search but only found to use stockers and no aftermarket.

Thanks

You can use either piston, but I like to use the 07-09 pistons on the 07-09 crank and the 10 plus on the 10 plus crank. The piston weights are designed to work with the crank and you will have better results this way. I don't see a performance increase for your application, so I would recommend using the correct year piston for your sled.
