For you guys with Amuse front bumpers, the underneath
 

Liquid G provided a picture of the underside of an Amuse front bumper. I'm in dilemma where I want to change my lip or just just go with a new bumper. I already have a brand new ZSpeed undertray (which if I go Amuse will be up for sale) to go on and am contemplating getting a Shine lip or an Nismo S-Tune, already have an Evo-R 3 piece lip (painted Magnetic black with carbon fiber center section - also will be up for sale) piece now.

My question, how much abuse does the underneath of a Abuse bumper take? Sorry, but I'm kinda anal even about how the underside looks, if after a short time under normal driving conditions these look like the wind blew and the **** flew, I'd rather just avoid going the Amuse bumper route. Car isn't a DD, but I do enjoy driving it when it's nice.

I do plan on lowering the car over the winter with coilsovers if that makes any difference. I've looked thru numerous posts but didn't find anything that dealt with this topic.

First, how are you going to service the car, Aka change the oil?
The other thing is I guarantee you will chew up the lip on that nose and worst if you lower.
I have stock sport suspension on my Z and I did the NISMO front bumper conversion Now I scrape the bottom of lip getting in and out of driveways that I didn't have problems with before.
One old fart to another!

Why would you sell the under tray if you got an Amuse?

To see how much you'll scrape, take every time you have scraped and multiply it by 10, then with lowering multiply that by 5

Right now I am not lowered so how many times have I scraped since I owned it - 8 months and about 7000 miles - zero.

I did another post where I asked about the undertray and didn't get many looks, can the undertray be used in conjuntion with an Amuse bumper?

Damn you then, lol
You will be 10 times more PRONE to scraping with the Amuse bumper then

And the under tray should be useable, no reason it wouldn't be.

I was kinda hoping you would say I wouldn't be able to use it so it would give me more reason to not buy one... This sucks... :)

Looking at that picture. I don't think you can use the Zspeed undertray and that front end together.

I have a stock height Nismo, and I'm getting ready to put on my 3rd black lower piece on my spoiler. When you least expect it. Scrap!

You could add a piece of sheet aluminium to the underside of the bumper, kinda pounded to fit or something. That could help handle the abuse and prevent hard damage to the bumper. I debated doing that on my next lip or bumper setup.

Looks to me like you can just use the hole at the rear of the undertray portion.

Would be a giant PITA if you had to take the fascia off everytime you had to change the oil.

When I raced formula fords we use to have rubbing blocks on the chassis so the frames wouldn't get abused from sitting so low to the ground. We would use a phenolic material

I am planning on running strips of teflon like plastic in strategic locations parallel along the bumper and skirts. Just to 'ease' the kit over low spots! Drilled and counter sunk with rivets to the kit.

you wont be able to run a z speed... and yes oil changes were a pain in the *** with this bumper.... the hole is super small (plus oil cooler thermostatic plate that small hole your screwed)... i ended up making a even bigger hole so oil changes were easier... as for the tray... i can imagine you cutting off the diffuser area but then the whole front bumper would be flimpsy....

disregard my post ^^^^ lol i read this last night and saw liquid G's post and was adding to to... im lowered and the main body of the front diffuser has NEVER scraped.... what will scrap thought is the main lip of mouth area... ive scraped that about maybe 3 times now... the correct way of angling and driving will prolong the underneath of your bumper :D

So if you have to work on the lower engine you will have to remove the front bumper to get to it ?

abcolutely.... it sucks... somtimes....
