Dont believe everything you read. The ST170 engine is just a 2.0 zetec, which runs a solid flywheel. The DMF merely reduces vibration.
The ST170 can be made to go quite well. But in standard form they are not up to much at all. I have both a 2.0 and st170 focus, and if it wasnt for the vct in the ST170 it would have been sold long ago.
