Which of these would you install on your car if you had both?

Jim M.

Correct me if I'm wrong but the M27 is front protection only and the M45 is front and rear. If correct then it's a no brainer. I got nailed about a year ago from the rear.

Jim, I'm sorry, but you left the door open and I had to go through it: "I got nailed about a year ago from the rear" Did you squeal like a pig?

Jim M.

Paul, you dirty old man! I got caught speeding with laser from the rear. He was parked on an on ramp when I went by.

OK, you stick to that story. Although I do not utilize this term, out of respect to the law enforcement community, some might say a "pig" was involved, right? I stand by my earlier comment.

The M45 is a quad front system with two low and two high.

M27 has two sensors, M45 has 4 sensors, you can put them where you want.

Where do you mount on the front of a 928 since there really isn't a flat place to aim for, close to fog/driving lights?

Okay, assume I install a pair in the rear, where do they go? If the front is hard, then the rear will be almost impossible, right?

Since I have made custom 1/8" x 1" T6061 aluminum brackets for the front grill, I can make or added extension bars as mount points. See picture below.

IIRC AO has a binder on his car. The sensors are mounted on the underside of the top grill opening with custom aluminum brackets. When I finally get around to getting one for myself that's where I plan to mount the front sensors. The rear will go where the license plate lights are with the lights being replaced with a smaller LED light for the plate (maybe in the center between the two sensors).
