Did you even read the thread? I don't want to come off as an asshole, but I answered this question on the first page.

Of course they will fit.


As a matter of fact, these two headlights are the exact same thing and are completely interchangeable; they just have different lenses, inner trim, and corners.

The only issue would be electronic, and all you have to do is reprogram your LCM (the light switch in the car) to accept xenons. Again, a dealership or anyone else with GT1 diagnostic tools can do this for you. If your car is early enough, it might require a newer LCM that can be programmed over, which isn't too much of a stretch either.

also the car would not have the autoleveling of the lights that factory ones have. so one would have to also get the frt/rr sensors and wiring looms to get them to perform like factory. but yes, they'll bolt in and light up.

Went through all the pages does anyone have a pic of a M3 bumper on a facelift sedan? Pic with no modifications just put on there and then pics of what it looks like when adjusted to fit?
Thanks
Max

M3 suspension, shocks, struts, springs...

now I know Alec isn't fond of this. But i've done the swap a few times.

#1 an M3 suspension is slightly taughter than the sport, but also, will ride slightly higher. My rationale. In the past now. 328ci, with 75k miles on it, sport susp. And for 150 bucks got M3 susp with under 10k on it.

Swapped well, was about 1/2 taller in front and 1/4 taller in rear (probably half that difference was the aging of the suspension). Car definitely handled better.

#2 Bought a 325i with stock suspension. i was getting seasick driving this thing. Swapped to M3 suspension. Lowered by about 1/2 inch front and rear, and much, much tighter. Handling was crisper as well as rebound was 1000% better. No floating, just nice firm M3.

My recommendations. If you have sport suspension and it's not worn out, or the M3 susp you can get is of similar milage, don't do it. If you have high miles on your sport susp and a low mile M3...will be worth it. If you've got a non sport susp - get the M3 susp, provided you can get it cheap. Remember you do have to get car aligned after this.

The technical issues.
1. Rear - direct bolt in. Hopefully you can purchase with top mounts too as they are much better than stock 3 series. The spring slips in and the shock bolts right in. Nothing to worry about.

2. Front - this is where the issue lies. The strut hat or top mount is M3 specific and your stock one won't work. So you need the entire strut, with spring and top eccentric mount from the M3 to make it work. Guys that have gone to coilovers will have removed this part, others with simple strut upgrades may not have. Without this part, the suspension is useless to you, and the part is i believe 90 bucks each at stealer...so unless you get the front hats don't buy the M3 suspension.

Now for the install, there is a trick, the eccentric top mount has an arrow that's supposed to face forward, with right on right and left on left. If you turn it (3 holes) so that the arrow is pointing towards the motor (inward) the alignment will be easy and more or less right on without any significant adjustments.

So yes after reading through this thread, and not seeing this info I thought it worthwhile to give you my experience. I do have an M3 (vert), and while the susp is not as balanced (lacking sways) in these other cars....it was definitely worth it...having purchased my sets for 150 bucks each.

Joe

^ Thanks for the input, I'm sure it will help lots of people. I'm still going to maintain the idea that it's just not worth it for the time/money spent. I bought my H&R Race springs for $140 and my car on those and blown non-sport shocks was absolutely on rails. I'm all about using OEM parts when possible, but I'm still not convinced that the M3 suspension is even an upgrade for stock non-sport non-M cars.

I'm sure with race springs it was tight, but have to imagine the ride was terrible. I can honestly say the improvement over a 'used' sport was very mild; however, the improvement over the non sport was quite impressive.

Actually it rode fine, extremely similar to my KWs, the only noticeable difference is high speed stability (and height, obviously.)

My Ride: 2000 328ci
M3 front

Hello
I've recently bought a 328 ci and wanted to give it a more aggressive look. Was thinking about the m3 front bumper. After doing some research on the matter i found that its not a direct fit. So i though about changing the whole front end of the car..... m3 fenders, bumper, and hood. The only thing about that is, seeing how the m3 has wider rear fenders on it. i imagined it would look odd to have wide fender on the front, and regular 3 fenders in the back.... with that said, i would like to know has anyone seen this done? and if so, does it look odd?(it would be great if you could post some pics of one that has gone through this) also, what is a alternative to this...in other words anyone know of a rear and front apron that will give my 3 a more agressive/sporty look. Thanks in advance for you replies.

Question, can you place M3 Eibach springs with non-M3 E46 Eibach dampners, on a 325Ci convertible? All parts are for 2001 E46.

Yes, it will fit. Here are the mods that need to be done.

- M3 transmission
- M3 engine
- M3 DME
- M3 cluster
- M3 LCM
- M3 shifter parts
- M3 engine harness
- M3 body harness, adapted for non-M sedan (rear windows (???), sport button, etc.)
- Traction control??
- Speed sensors?
- all necessary brackets, etc. etc.


All of which, you have to find and do yourself. Your best bet would be to find a wrecked (in the rear) M3, strip both cars down, and swap all the M3 parts into the 325... we're talking every single part here. This will end up costing you a fortune of money and time, especially on the research end of things.

Eibach M3 springs will probably raise a 325 sport. M3 is a heavier car. Either way, not worth it at all as there are much better and 'worry-free' options for your money.

Everyone should really read or search the thread before asking questions!!!! =/
