TCochrane92's Z4 Coupe Progress Thread

Post by Tcochrane92 » Wed Apr 19, 2017 6:25 pm

So I've had my E86 for about a month now and thought it might be nice to have a thread to show my progress. Hopefully containing some useful information for someone too!

Previous to the Coupe, I had a pre-facelift titan silver 3.0i manual roadster. Loved everything about it, but just really fancied a coupe.

So the car is:
Model: Z4 Coupe
Trim: Sport
Colour: Silbergrau
Transmission: Auto
Factory extas:
- Sport package (seats & suspension)
- MFSW
- Parking sensors
- Satnav
- 10 speaker system with DSP
- Xenons
- Cup holders
- Electric folding mirrors

Aftermarket extras done before me:
- Wheels: Lenso ESG - https://www.wheelbasealloys.com/alloy-w ... wider-rear
- Stubby aerial :poke:
- Sound gen mod
- White LED numberplate lights


1. First thing I did was get the Ducklakeview exhaust mod done. Sounds absolutely amazing, how BMW should have made it sound from factory in my opinion!
Info: viewtopic.php?f=2&t=89154
Price: £250
Video: https://www.youtube.com/watch?v=MgTLOlomKec

2. Changed all badges to carbon black ones.
Bonnet, wheels, steering wheel & boot: £16.99

Unfortunately the wheel badges didn't fit the Lenso wheels :thumbsdown: about 2mm difference!

Indicator roundels: £8.99

3. Changed halo sidelights to white LED's. They're about the same brightness as the standard 10w halogen bulbs, but give a nicer modern look. I jacked the car up, removed the wheel and got access from the back. You remove the sidelight assembly with a torx screwdriver, yank out the out bulb and use a small file to allow fitment of the new LED.

Price: £3.65

4. Changed foglights to LED's. You can change these in about 5 mins total, by rotating wheels to full lock. These look really nice with the white halo sidelights in my opinion (I use them as DRL's)

5. Next I wrapped the roof in gloss black vinyl.

6. The lower lip on the front bumper was quite heavily stone chipped, so I covered this in black vinyl too. Also think it looks quite cool :thumbsup:

7. Here I cleaned, clayed, polished and waxed every body panel. Untreated panels felt like running your hand over gravel in comparison to the glass-like finished panel! No swirl marks or scratches, damn near showroom condition IMO

- Royals wheel refurb
- Renew engine parts
- High flow air filter
- Dyno mapping
- Change all bulbs to LED's
- Replace tired xenons with new

- Change to clear 3rd brake light
- Carbon boot spoiler lip
- Paint brake callipers
- Change brake pads to Brembos
- Change brake discs to upgraded ones

Very nice, some tasteful mods you've done. I like the 2 tone black and silver thing you've got going on too. I'm definitely going to look into changing the angel eyes as you've done, looks great.

Not bad for a month.

It's a good thing you've got springs on your list as I'm pretty sure someone has replaced your rears (that very commonly snap) with non M Sport ones given the disparity in ride height.

The pictures are deceiving, its parked on a hill and sits back on the handbrake, relaxing the rear suspension. It looks very different on level ground

Really great thread. I like the roof wrapping and badges, looking awesome on the silver grey.

9. Alignment
As suspected, the toe angle was very wrong, simple alignment and all fixed! :oops:

Looked at your list, you can't get clear rear brake for coupe, not from BMW anyway.

I think you should add LSD to your list, literally the best mod I've done, that and suspension refresh really make it handle well.
I can help you out with the LED conversions and coding.
