Exclamation * How To Fit OEM M3 Parts On A Non-M *

Since a lot of threads pop up about fitting OEM M3 parts on Non-M cars, I figured we might as well have a thread that explains everything. This will be a list, hopefully including part numbers, of everything you'll need to fit OEM M3 parts on a Non-M.

---

Front Bumper:

Difficulty: 4/10
DIY: Maybe.
Installation:
- Coupe: http://www.e46fanatics.com/howto/how...hp?howto_id=40
- Sedan: http://www.e46fanatics.com/howto/how...hp?howto_id=41
Part Numbers:
- Re-Bar: http://www.realoem.com/bmw/showparts...29&hg=51&fg=15
- Bumper: http://www.realoem.com/bmw/showparts...81&hg=51&fg=15

This will fit on okay, but will need some tinkering to fit flush with the stock non-m fenders. Without modification, the bumper sits about an inch and a half forward and the sides flare out an inch or so; on a sedan, it's a slightly bigger gap. To fix this, some people opt for the OEM CF reinforcement bar and stretch the sides in a little bit, while others simply shave down the stock bar to allow the bumper to sit farther back.

Safe Alternatives:
- OEM Mtech2 front bumper (available at your local BMW dealership)
- M3/ CSL replica bumper (available through many of the sponsors here at e46)

---

Front Fenders:

Difficulty: 5/10
DIY: If you're looking to save money, then a DIY would be nice.
Part Numbers:
FRONT LEFT 41357894337 $281.23
FRONT RIGHT 41357894338 $281.23

The OEM M3 Fenders will fit on nicely, but will be wider than the stock coupe front bumper. An M3-fitment front will fit perfectly flush with these.

Safe Alternatives:
- Racing Dynamics Tornado

---

Hood:

Difficulty: 4/10
DIY: Absolutely.
DOES NOT FIT SEDAN!
Part Number:
HOOD 41617894223 $558.00

Minor fender modification is needed for 100% fit. Most people do this by simply spacing the fenders out by using washers.

Safe Alternatives (for coupes/verts ONLY):
- Carbon Fiber (available from many aftermarket companies)
- Vorsteiner GTR
- Hartge-Style

---

Mirrors:

Difficulty: 2/10 (coupe/vert), 4/10 (sedan/wagon)
DIY: Yes.
Installation:
- Coupe: http://www.e46fanatics.com/howto/how...php?howto_id=6
- Sedan:
... Assembly: http://www.e46fanatics.com/howto/how...hp?howto_id=27
... Base Plate Modification: http://www.rogueengineering.com/Merc..._Code=E46M3MIR
Part Numbers:
RIGHT PRIMED EL.EXTER.HEATABLE MIRROR 51167893468 $232.13
LEFT PRIMED EL.EXTERIOR HEATABLE MIRROR 51167893597 $232.13
ACTUATOR LEFT 51167895273 $169.63
ACTUATOR RIGHT 51167895274 $169.63
MIRROR GLASS HEATED PLANE LEFT 51167157247 $46.59
ADAPTER LEAD, MIRROR HEATING 51167836442 $6.58
MIRROR GLASS HEATED CONVEX RIGHT 51167157244 $58.31
ADAPTER LEAD, MIRROR HEATING 51167836442 $6.58

On coupes and convertibles, they're a direct bolt on. For sedans and wagons, the bases have to be modified slightly.

Safe Alternatives:
- M3 Replica Mirrors (M5-look) (available through sponsors)
- Hammann/Hagus (available through sponsors)
- AC-Schnitzer (available through sponsors)
- e36 M3-style (available on ebay)
- Hartge

---

Side Skirts:

Difficulty: 2/10
DIY: Yes.

Direct bolt on. No modifications needed. On sedans and tourings, the skirts will be a couple millimeters too long. No biggie though...

Safe Alternatives:
- Hammann GTR
- Hammann Competition
- OEM Mtech2
- AC-Schnitzer
- OEM Aero Kit (a.k.a. 'Mtech1')

---

Rear Quarter Panels/Fenders:

Difficulty: 9/10
DIY: NO!
Heavy modifications are needed for these to work. In short, a body shop will need to cut your existing quarter panels to smithereens and weld the M3 ones into place. This will require many hours of labor and lots and lots of money. This process is also irreversible. Only do this if you're absolutely certain that your pocket can take the hit.

(Not-so-safe) Alternatives:
- Custom widebody

---

Rear Bumper:

Difficulty: 6/10
DIY: Probably not.
Part Numbers:
- Re-Bar: http://www.realoem.com/bmw/showparts...06&hg=51&fg=15
- Bumper: http://www.realoem.com/bmw/showparts...19&hg=51&fg=15

This has only been tried a handfull of times, but this mod is usually accompanied by a widebody. Since there's such a difference between M and non-M rear fenders, this bumper is a good inch or two too wide. To fit this correctly, you'll either need to do some hardcore molding and reshaping of the bumper, or a custom widebody in the rear. If you can deal with the bumper flexing and creating numerous noticeable gaps, then I guess you could do it without modifying anything (and only stretching the sides of the bumper in). Again, this mod isn't highly recommended unless you're serious about modifying your car.

Safe Alternatives:
- Hammann GTR
- Mtech2
- OEM Aero Kit (a.k.a. Mtech1)
- Various rear addons

---

Trunk (including CSL trunks):

Difficulty: 3/10
DIY: Yes.
DOES NOT FIT SEDAN!
Part Numbers:
- M SPOILER REAR, PRIMED 51717893671 $139.50
- TRUNK LID 41627065260 $430.78

Some people (for whatever reason) want OEM trunks on their cars. The trunks are the exact same dimensions for M and non-M cars, therefore this is a direct bolt-on. No biggie.

Safe Alternatives:
- M3 Trunk Lip (yes, it fits fine)
- CSL Replica Trunks (Vorsteiner)
- CSL Addons (eh)
- Bimmain CSL-Style Addons (very nice looking IMO)
- ACS 3-Piece Race Wing
- ACS 3-Piece Trunk Spoiler
- ACS 1-Piece Trunk Spoiler

---

Muffler:
Difficulty: 4/10
DIY: No. (leave it to any reputable muffler shop)

Despite what many people think, this mod isn't very hard to do. Here's what you'll need to do:
- Either cut the spare tire well ($100ish) or get an OEM M3 one put on ($150ish) in order to allow room for the muffler box.
- Get a new rear bumper to accomodate the sexy, center-exiting, quad tailpipes.
- Go to a muffler shop and have them weld it on. Just the welding and bracketry shouldn't cost more than $100 in total.

Safe Alternatives:
- Custom quad exhausts
- Remus/Eisenmann quad exhausts

---

Wheels/Tires:

Difficulty: 4/10
DIY: Sure.

To get a set of four to fit, you will need to do some hardcore fender rolling and buy some smaller tires. To ensure proper fitment and to avoid a headache, I'd probably just find a set of four front wheels. These will fit just fine with no rubbing or modifications or anything.

Safe Alternatives:
- Anything

---

Gauges/Instrument Cluster:

Difficulty: ?/10
DIY: ?
Part Number: INSTRUMENTS COMBINATION UNCODED MPH 62117837972 $504.43

This has not been successfully done yet. People have plugged these in, and here are the results:

WORKS 100%:
- MPH
- RPM
- OnBoard Computer Functions
- Lights
- Indicators
- Engine Temp.
- Gas Info

DOES NOT WORK:
- Oil Temp. Needle
- RPM Warmup Lights
- Little orange ODO Tamper Light comes on...which is bad

This is a DIRECT PLUG AND PLAY, but will not work 100%. You be the judge...

Safe Alternatives:
- Bimmian M3-Style Gauges
- UUC Whiteface Gauges
- Silver Gauge Rings w/ Red Sharpie'd Needles

---

Steering Wheel:

Difficulty: 3/10
DIY: Yes
Part Number: M SPORTS STEER.-WHEEL, AIRBAG, LEATHER, BICOLOR 32348022322 $700.29

As long as you have the round airbag, this will be a direct bolt-on. The airbag, horn, radio buttons, cruise control, and everything else will work. Yay!!

---

More to be added later....

Alright, here are just a couple little things..

TAIL LIGHTS:
- DO NOT FIT SEDAN
- Totally interchangeable between M and non-M coupes, or M and non-M verts (however, coupe tails are different than vert tails so they are not interchangeable between body styles).
- No modifications necessary.

HEADLIGHTS/FRONT CORNERS:
- DO NOT FIT SEDAN AS-IS (see below)
- Headlights and corners are totally interchangeable between all coupes and verts.
- Headlights can be fitted to sedan if the lenses and headlight trim pieces are swapped.

FRONT KIDNEY GRILLES:
- DO NOT FIT SEDAN.
- Fully interchangeable for all coupes/verts.

REARVIEW MIRROR:

- Fits all e46 without modification.

SUSPENSION:
- SHOCKS/STRUTS: Possible, but not worth it (minimal performance/aesthetic gains)
- SWAYS: Nope.
- RSM's: Yes.
- STRUT BAR: Yes.

BRAKES:
- No modifications needed except for custom caliper carriers to support the bigger calipers and rotors.

Any idea if the Clubsport Splitters will fit on the E46 325Ci (2003) bumper?
Some of the dealer parts departments I checked with "thought" they would fit, but no definite answers.

Thanks for the write-ups

Not without custom work... they're designed for the Mtech2 front bumper.

I'm pretty sure the M3 springs will require modification to fit a non-M..


I'd look here for used suspensions: http://forum.e46fanatics.com/forumdisplay.php?f=35

^ Whatever fits your budget.

You should probably write that headlights/corners/grills are all interchangable for the non-facelift....just in case people forget or something

Great compilation of info and previous DIYs Alec!
You might consider to make a few notations/additions or possible changes for people who might not know.
*The early coupes have clip-in front turn signals. These will not swap with the screw-in type holders of other later model M3 coupes.
*One should get two more rear upper side clips for the M3 sideskirt retrofit as the non-M3 doesn't have them and it'll stick out.
"SAFE ALTERNATIVES" to the M3 rear lip spolier for Sedan would be the M-tech sedan rear lip spoiler (aka sedan ZHP rear lip spoiler #51717894050 $147.31). The trunks did change somewhat on the models, the trunk handle(over the LP) was much longer on facelifted years.
*And although the M3 Oval rear view mirror will retrofit without mods, to have all functions work might require some rewiring.

What if you don't have the round airbag? Is there a way to purchase one from the dealer and make everything work?

Yes, you just buy the round airbag (~$400) and plug it in. All e46 steering wheels are compatible with their corresponding airbags.

Not necessarily plug & play, but pretty damn close. There are a few retrofit kits out there... Search the forums for "Paddleshift Retrofit".
