Does the tuft-testing reveal any hope for an extended decklid ? Should it be flat or raised at a certain angle as some have suggested ?
For some reason, I want to try and mimic the Renault Logan eco2, with perhaps a slightly extended version of that spoiler. The combination of VGs and that decklid seems like a good idea on a 3-box car. My Echo has a somewhat similar design all-around and it could benefit from it. The detached airflow in the middle of the rear glass needs to re-attach more smoothly for an extended decklid to be efficient. Am I wrong ?
