the part that is attached to your front bumper? that bottom plastic piece. does it matter if i take it off since my new bumper does not reach the plastic piece?

 

Yes, taking it off is bad. It serves 2 main purposes, to keep crap out of your engine bay, and it's one of the aerodynamic components that gives the G35 zero lift in the front.

 

thats what i thought.. and i am looking for more ways to create more downforce at high speeds.. guess ill be keeping my stock bumper on then. know of any tricks to help get greater downforce and more control of the vehicle at high speeds?

 

I think you're referring to the same piece that I asked about in this thread ===>

Check out that thread.

 

thanks ^^

 

Unless you regularly travel around at 150MPH+, there really isn't a whole lot you can do to increase downforce short of installing HUGE rear spoilers and front chin spoilers.

 

I have not had mine on for quite some time, and done a few track days. I have noticed zero change to the car.

 

What kind of bumper did you get that doesn't work with the undertray?

 

I just removed mine. Had no problems since.

 

Mine is removed as well.

 

I am going to keep mine on. It helps protect from water and debris.

 

Its designed to aid in cooling and the cooling system is designed and tested with it in place. Sure you can roll without and probably notice no ill effects but why. It also serves as a nice debris shield. Many think that its worthless but it does more then you know. If you ever have the pleasure of something flying up off the road and tearing your belts up and get tangled in the fan like I have then you will learn to appreciate them. Keeps those damn cats out in the cold weather too. You may laugh but I have seen many animals that made a nice home in a warm engine bay in the cold season. Its a mess to clean up!

 

How does it aid in cooling? There are tons of cars out there that do not have the underbody panels (Camrys, Corollas etc) and still on the road.

 

Give me a break people. Underbelly panels? Seriously.

Check your car's manual. I bet you will see a recommendation not to mod your car at all because Infiniti engineers designed it that way and everything on the car "has a purpose".

If the car truly is mechanically perfect why would any of us mod the car in the first place? Infiniti is simply trying to reduce the liability risk of some noob that doesn't even know if it will be a problem to remove plastic panels under the motor from trying to modify their engine or car in the first place!

Just my .02.

 

i got the extreme dimensions bumper.. i think its in my pictures. i painted it OB and everything and it fits fine just doesnt fit that underbelly plastic **** thing
