Goin' Down the Z4M Bumper Road ...

Hello Folks ..

I picked up a used bumper last week on Ebay ..
They are few and far between ..And I was lucky to be able to avoid shipping by picking it up myself.
I paid too much cause it came with grills and centre grid.
On closer inspection there was some damage to the centre grid (some of the hexagons are cracked but still lock into position :(
Not to worry ...
Its a project that presents some design and decision making ...A perfect opportunity for me to learn something new ..

All the parts that came with it.


Damage to spoiler...Scuffed and twisted. A Heat Gun worked wonders on any bits out of shape.


To fill a hole or buy the rediculously priced BMW Plastic Bit ? The Body Shop will provide the final answer.



1. Repair or replace ?
I can replace the centre grid or I can fabricate some expanded metal (sold as a replacement grid from a tuner shop) and repair it.
Im leaning towards replacement seeing as the grid is subject to much abuse. Maybe put the expanded metal behind it to protect the radiator.

The Grills are chrome with black. The trim shows some pitting, but I still have the stock chrome with dark gray and the all black ones that Im running now.
Lots of choice there but right now Im leaning towards using the original chrome trim with the black grills.

I need the dreaded reflectors, washer covers and tow hook cover.
This is the most troublesome because I would like to fill in all of those openings.
Ill get an estimate from the body shop first to see if the body work is off the wall on price.
The reflectors present a significant hole and maybe I should just buy the damn things and get them painted ..
Decisions Decisions ..

I have a parts list for all the regular bits required and luckily my friendly neighbour is the Parts Manager at the local Nissan Dealership ...
So he can get me a price advantage there ...
Plus I visited my Ol High school to call in on the Welding Teacher there. He is fabricating some abrasion plates to put under the front spoiler.
He calls them Pedestrian Slicers !
I have extended them about 3/4 of an inch. I might paint them or I also have some 3M Di Noc that I could wrap them to look like carbon fibre
Aluminum, Stainless or mild steel ? ..No problem ? Actually its the same materials that I got from a local fabricator when I was teaching there.
I made the template and the kids cut them to demonstrate Plasma Cutting. A Win Win ....

Im in no hurry to complete this mod ... Full factory warranty till mid May ..
I don't want any hassles during my last service under warranty.

Stay tuned

Cheers

After some consideration of my options:
I decided to do some additional investigation.

First I went the coward's route and took the bumper to a local autobody shop.
When the Chev Malibu was rear ended a few years ago, a completely new bumper installed was $800.
Now to just get a respray on the Z4M (with repair on the scuffed spoiler) ...$985 ...!
Whew ..I now understand that owning BMW puts a target on your back with a dollar sign as the Bulls Eye.

So I did some more thinking and You Tubing and decided I can do all the body work.
Im retired after all, and spent a good portion of my career showing kids how to sand surfaces until they are as smooth as the top of my head.
Even filling in the front reflectors and headlight washer ports would be a learning experience..
What with all the adhesion promoters and flexy primers required in polycarbonate part repair,
Just give it a go.
Presenting a totally prepped bumper for just a respray ought to be more reasonable than $985.

So I know the mounting parts required to do this conversion on the cheap...
A couple of brake duct horns
Two metal brackets that support the 'horns'
The tow hook cover and some sort of related clamp.

I have the parts list , exploded diagram and even a price list, thanks to the various Zed Forums.
Looks like the Brake ducts go for $33.90 each, Brackets add another $16.75 a piece, and the tow hook Eye Flap adds another $12.39 .
I'm expecting some inflation, shipping etc ..But the starting point of $115 seems like SWMBO won't even notice.

My Ace in the Hole ..
My neighbour is a Parts Manager at the local Datsun Dealership.
And he is my discounted source for parts ...
I just have to pick them up and pay cash, while pretending to be a Datsun employee retrieving items for the body shop.
I've done that to save a buck or two.

I Email him my order and beg for a favour ..
No problem ...
A day later he sends me a reply / confirmation before he places the order sending me into my Datsun Disguise...
OMG ..Stealership Bandits ..
They want $289. plus tax ..
And this apparently already includes a 28% discount !!!!

So now I am back in Reconsider Mode...
Like how come the price on those bits of plastic and bent metal are so out of whack
And now I understand why your M Style Z4M Bumper Kit has suddenly inflated prices.

My question after all this ?
Like what gives?

Confused Bumpy

ps ...If Euro Prices are accurate ..I know what Im shopping for while on our Euro Splendor Summer Tour.
 
wow im looking for a M bumper myself at the moment so ill be keeping a close eye on this thread! keep us updated with plenty pictures of how you get on!
 
Hey srhutch ...
You get my email ?
Wing insert is black and back says RH #7033066
Black part looks perfect
Lens is orange and also looks perfect.
Rondel has minor damage, although I could live with it.
A small scuff by the B and a chrome bubble on the M

Lemme know if you need it ...

Cheers
