Mod # 60, Boost Gauge

     I relocated the boost gauge for better visibility. I ran the wires and vacuum line through the dash. I fabricated a small aluminum bracket to position the gauge. Next I will fabricate a rear cover to hide the wiring.

Mod # 56 + 65, Scangauge + Bracket

     After using the Scangauge for quite a while and finding it very useful I decided to replace my broken OEM driver's side cupholder with a small aluminum bracket I fabricated to mount the Scangauge. This also cleaned up the OBDII cable by hiding it inside the dash and routing it through the bracket.

Mod # 54, Ultimate Cupholders

     Ultimate Cupholders rule! They are cheap, durable, ideally located and fit pretty much every cup and bottle known to man.

Mod # 50, Added Homelink

     I added a Homelink module from the E39 5 Series, so I could open my garage doors. There are less expensive products on the market, but I preferred the OEM look. Tom at EAS helped me with the wiring.

Mod # 49, Pedal Covers

     These MRTM pedals were originally designed at BMS. Since the first prototype the designer has purchased rights to the design, started his own company (MRTM Design Inc) and refined the pedal design. The pedal covers are machined aluminum and have no rubber inserts. Contrary to popular belief, rubber insert do NOT increase traction between the pedal and driving shoe. I've tested these pedals with dry and wet shoes and in both cases traction was improved noticeably vs. stock. Best of all, the more rigid aluminum dramatically increases pedal feel.

Mod # 39, Removed Emergency Trunk Handle

     This annoying piece of white glow-in-the-dark plastic has a habit of presenting a strong glare in one's rear view mirror. I can be dangerously distracting, so I removed it. You can still open the trunk from inside by pulling the metal cable.

Mod # 34, Removed Sun Visor Warning Labels

     I used Goof Off, not to be confused with Goo Gone or any other similar product. I strongly recommend removing the visors before applying Goof Off. Also, re-hydrate the visors with an appropriate conditioner after removing the labels. I used Lexol's Vinylex.

Mod # 29, First Aid Boxes

     I got these for miscellaneous storage, not specifically to store BMW's first aid kit. They are pretty light and add a lot of storage to the small Z4. They retail for about $30.

Mod # 28, Seatbelt Guides

     I am not a fan of the stock BMW Z4 M seatbelt guides, they guide the seatbelt to rub my neck. So I got some screws, nuts and rubber doorstops from Home Depot. The resulting construct allows me to keep the seatbelt from riding up the BMW guides.

Mod # 22, BMW Cargo Net

     I thought that the Z4 M trunk really needs a cargo net, and after the BMS battery tray mod (see Mod #13, below) the trunk was square. I got eye bolts from Home Depot and a BMW E36 cargo net. I carefully measured the hole placement, then drilled and tapped the holes. The I secured the net hooks to the eye bolts. The small nuts keep the eye bolts from rotating. Please excuse the in-progress pictures below, I had not yet gotten new trunk panels made to finish the BMS battery tray mod.

Mod # 19, Aluminum Roundel Stickers

     My M Coupe has brushed aluminum trim, fitting as there is a lot of aluminum used throughout the car. Because of this I opted for Bimmian's brushed aluminum roundel stickers instead of the more common carbon fiber stickers. I like the look and the individuality of the brushed aluminum.

Mod # 15, CG-Lock

     I find this product does a decent job of holding one's lower torso in place during hard cornering. It's not as effective as a real harness, but it's not as expensive or as cumbersome to use. Buckling up does take a little getting used to compared to the stock BMW buckles, but it's relatively easy.

Mod # 14, DVD player

     This mod was installed to work through BMW's OEM tv tuner (see Mod # 9, below). It allows me to watch DVDs on my Nav screen through an Aux input harness. I also wired up a switch so I can power up the DVD player and switch DVDs while the car is off. Typically on long trips it is convenient to switch DVDs during fuelups.

Mod # 13, BMS Battery Tray

     This mod was done to save weight and increase space in the Z4 M Coupe trunk. It started with the Odyssey 680 battery, which is strong enough for the BMW Z4 but can lose its charge more quickly than the stock battery. Then BMS designed and machined a billet aluminum battery tray and clamp. After installing the tray and battery I examined the space and determined that the M Mobility kit foam canister would fit above the battery. So I fabricated a bracket for it. I then made mock-up replacement trunk panels out of cardboard and later, carpet. I designed the left and right sides as flaps so that I could use the interior spaces for storage of the DVD player (see mod # 14), BMW Z4 Owner's Manual and BMW Z4 tool kit. They also allow me to access the rear shocks' rebound adjustment screws. A shop in Costa Mesa fabricated my trunk panels, but they are not good enough quality to sell to customers, which is why this whole kit is not available from BMS. The battery tray is produced and for sale, if you want to keep the stock battery cover or you are building a race car.
     Note: The M$RP below reflects the cost of the BMS battery tray, Battery, custom trunk panels and material for the IMS bracket. The Install Time is an estimate of the time necessary to install the finished components.

Mod # 12, Imola Red MkIV Armrest

     I love the MkIV armrest. It installs very easily, holds small objects very securely, and greatly reduces driver fatigue over long distances.

Mod # 12, Imola Red Shift Boot

     I bought this to compliment the other Imola leather in my cockpit. As with all their BMW products LeatherZ only uses BMW hides, so you know it will exactly match your existing leather.

Mod # 9, Nav TV

     This mod was a collaboration of multiple components. First was an OEM BMW tv tuner. This installs easily into the Z4 M bulkhead. The BMW antenna wires and boosters get mounted inside the rear bumper (the most time-consuming step of the mod). The BMW wire loom and video block mount in the right rear of the trunk. I also got a TV-In-Motion harness to fool the BMW computer into allowing TV viewing over 3mph.

Mod # 5B, iPod Mount

     This holds my iPod in a very accessible location and does not black any BMW controls.

Mod # 5, Monster iPod Cable

     I use this to charge my iPod and, with a 3mm wire I picked up at Radio Shack, to plug into the stock BMW Aux Input.

Mod # 3, Calculator

     Not a big deal, but technically it's a mod. I keep a precise fuel log and as such have found it useful to always have a calculator in each of my vehicles. I velcro'd this one inside the BMW storage compartment cover.
