Haha very true. So one more detail that I want to make sure I get right. The outer grill slots are recessed quite a bit compared to the center one. I'm assuming I still want the outer sensors pointing straight ahead, but should I avoid being too close to the inner edge? Or will the center sensor pick up the slack there?

I agree with RR about just inward a smidge on the green (maybe a head length or so), however, with your install and the recent picture you sent the real key is you need to make sure the heads DO NOT follow the drastic curvature of the front end of the car. That can be tricky, but they (all 3 heads) should be pointed directly ahead, with none following the contour of the front end.


For the outer most heads this means the outer edge of those will be sticking out further then the interior (none of the head -especially the bubble-should ever be recessed under/behind the bumper). There was an old saying (not sure if you kids use it anymore): Stealth the ride, not the install. Thankfully the ALP heads are tiny, so it's not a big issue like it would be with a wider head.

I ran into a lot off issues getting access to those lower outside mesh grilles so ended up settling for a two sensor install for now. When I find the time to take the bumper off I'll go for the 3 sensor install based roughly on the green positions. But for now here's what it looks like...



It's hard to tell from the pictures but I've got them pointing straight ahead (maybe off by a few degrees) and level parallel to the ground.
