Short length buggy motor?

[sw2kid]

I'm looking for any opinions on a brushless motor. I have very limited space in my buggy so I need a shorter motor, anything under 68mm will be a tight fit but will work. I was looking at some kontroniks stuff and they have some motors within that length. Has anyone ever run something like that in a buggy? The buggy that it will be going in is a mugen mbx6r and will be running on 4s lipo if that helps at all.

Thank you all for the help in advance.
