Just got my new Trinity D4 (1s Short Stack) in the mail and installed it last night. The mounting holes for the motor are only on the "bottom" half of the motor (not 360 degrees around). I guess this thing is geared towards touring cars.
The downside for me (and my 4 gear trans) is that the wire mounts on the motor are now angled pretty significantly toward the rear of the car. Looks like I'll need longer wires....unless there's a way to "clock" the case on the motor, but I don't think that's possible.
