Im thinking about a centro just because my home track is a carpet outdoor track. And rear motor is just terrible out there no matter what.
Not sold on mm on dirt as one of the guys I race with had a x factory car. My local indoor is too small for a mid motor to shine in corner speed because its alot of hairpins on this current layout.
Granted on a bigger track were you can carry alot more speed through the corners I think a mid motor would be awesome espically for stock!
