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
- 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

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 about 2mm difference!

Indicator roundels: £8.99

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.

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)

Price: £13.29

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

Price: Roughly £50

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

Price: Roughly £20

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

8. Removed wheels to clean, polish and seal to bring them back to "as new" condition. They have absolutely no marks whatsoever.

To do: (in no particular order)
- Alignment - done!
- Cruise control retrofit - done!
- Wheel balancing - done!
- Wrap interior in high gloss carbon fibre
- Eibach suspension
- Ram air scoop
- Flush & change engine oil (inspection 2 has recently been done, but I'd like to have extra peace of mind!)
- Change transmission fluid
- Change differential fluid
- Royals wheel refurb
- Renew engine parts
- High flow air filter
- Dyno mapping
- Change all bulbs to LED's
- Replace tired xenons with new
- Update maps DVD
- Replace GPS antenna (lost GPS signal )
- Change to clear 3rd brake light
- Carbon boot spoiler lip
- Paint brake callipers
- Change brake pads to Brembos
- Change brake discs to upgraded ones
- Change brake lines to braided ones
- De-badge 3.0si side badges
- Change to ///M front bumper
- Change to gloss black kidney grills to match gloss black roof & lower lip bumper (currently matt black)

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.

Been thinking about wrapping my front bumper but wasn't sure... looks good here

Thanks guys

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

10. Cruise control retrofitted!

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.
