Undertray Yes or No???

Postby ScottyHull » Sun Mar 02, 2014 7:47 pm

Hi,
I am going to service my car myself this week and was thinking about not putting the undertray back on the car as its a pain in the arse to take off and put back on.
Is this a good idea or should i put the undertray back on, does it help anything structurally or not and also does it protect anything from normal driving elements? :?: :?: :?:

Thanks for you help in advance.

I would definitely fit it back ... Just imagine all the dirt that is going to get onto the engine. Besides that it might (although I doubt it) influence aerodynamics slightly but that's about it as far as I know.

Ive been driving mine for about 2 years without one on and its been fine.

I found the undertrays make it harder to tell if you got an oil leak as it collects on there and not the floor.
also if your working under the bonnet and you drop a bolt you have to then take the undertray off to get bolt.

+2

there is an undertray for a reason, not only to make the car more expensive... and it is held by 9 bolt (or less)

I am not fussed about aerodynamics to that slight extent. I don't seem to catch the tops of speed bumps (should I say speed mountains in my case where I live) while it's removed so I think I won't put it back on until I sell it. Thanks for the advice guys.

It's just so much easier without it on. Don't have to take it off the bumper when you need to change bulbs/ oil and filter changes etc. :cool:

You don't have to remove the entire undertray from your bumper when removing from the car when you should change your bulbs ;) Besides there are only 3 10mm bolts underneath, and you do not even spend one minute removing them.

The undertray is there for a reason, and it is not for annoying the owners of the cars ;)

If it's there for a reason what is it besides aerodynamics?

1- if you hit something underneath and you hear it it is hitting your undertray, it will warn you that you are close to your engine, / no undertray, the first thing it will hit is your oil pan,
2- lot of times the air/tires will pick dirt, rocks, water... and will "push" it in your engine bay.
have you noticed when you hit a water how it sprays away , it sprays in both direction (to both sides of each tire) I prefer my engine not being washed by that water.
etc etc....
oh yea, the undertray actually increases the cooling of the engine/radiator then without it.

Thanks for all the info guys. I'll leave it off until next time I service the car.
