So no, I don't believe that is possible because what you are trying to tell me that rock can shoot forward from under the car and so I should worry about the car behind shooting rocks at my bumper.

I think we have enough to worry about lol

It is one thing to have legit concern but it is a different thing to make up scenarios that not quite physically valid.

That was me. One drove too far into a curb. The other was driving down I5. Both had engine failures. Both were M3s.

What you're doing is discounting all of the variables that are involved. Doesn't matter that a tire is spinning unless the tire grabs onto the rock and pulls it in the direction it's spinning. If, however, it rolls over the rock on its edge it will simply pinch it and shoot it off.

I would guess that someone who installs the skid plate will also likely install the front grill guards, but there is still rational in your question.

If you puncture your oil cooler under the car, you can blow your engine in .5miles or less. This is proven.

When I punctured my radiator I drove home for an unknown amount of time and got no warning. Then the next time I started my car I got a "low coolant" warning. I just topped off the coooent and drove 30 miles to work looking at the temp. It wasn't until I visually saw the coolant pooling that I realized there was something wrong.

In other words, a punctured radiator is much more forgiving, and therefore isn't as high a priority.

This is exactly the difference, the oil cooler is not at all forgiving, the cooling system will take a small puncture and you get plenty of warning - maybe

Picture a cold day and a broken radiator, you get low coolant way before high temp. What is the status of your engine? Keeping in mind that you may not get a timely high temp because the temperature sensor is normally submerged but now is not. How long for engine heat to soak the sensor?

For the rock to shot forward, something need to give it force in that direction.
Sure if the rock is shape like a triangle and then you drop the M2 on top of that, yeah, I can see that.

But a spinning tire that is on the ground? If what you said would happen, our factory assembly lines where convey belts and sorting wheels is going to have more problem than jamming.
Imagine all the stuff that could fling out in the reverse direction. lol

Keep in mind with Newton 3rd law is the reaction force. The ground goes backward in relative to the car going forward. Your rock is part of the ground, even though it is loose, but does not mean that wheel can send it forward.

Personally not a fan of the Zunsport look; has anyone installed the Stradale Design oil and/or radiator gaurds? Any thoughts?

Does just doing the under oil cooler provide enough protection? Not a fan of the front protection look. Also is just an under one sold seperate?

Each protector protects a different thing. The one in this thread is discussing protection for the oil cooler from underside impact.

I’m like you and only ordered the bottom skid plate. All are sold separately, whichever brand you choose.

Mind you, some folks go for the front protection because we had a member who had his radiator punctured, so he was losing coolant. That requires front grilles.

I got the Zunsport front grill and only putting on the center piece just simply because I hate seeing full size leaves getting in and just sitting there. I don't think it provide much "protection" to the front radiator. Just don't like leaves getting in lol

Ok take it off and observe the opening. Reinstall and observe the opening. Im not at all sure what you are seeing. Not much protection is the status of it being uncovered. Maybe check your prescription or you failed basic physics lol. It will be deflecting far more than it not being covered. A member posted here he has seen a Zunsport screen survive and protect a deer impact. What more do you want.

"protect a deer impact"? what does that mean?

All I know it kept almost 99% leaves out so mission accomplished for me. I don't think I want any of this deer impact thing. I rather drive around that.

[Carefree]

Here’s a radical suggestion. Add extra protection if you choose. Otherwise, don’t. Apologize ahead for the extreme idea.

Now you are just trying to radicalize me with extremes

Found a video on the install for the center radiator; it looks pretty straight-forward, but haven’t found anything on the sides or the oil cooler.

However he mentioned manuals have some protection, curious how much and if I will even need this then? Maybe just the oil cooler guard.
