Hey Im kinda new here was wondering if there was any way I could get my hands on some headers for my z4M. My front suspension needs replacement as well. any help would be most apreciatd. !

Are you looking for aftermarket headers or OEM? What is wrong with our front suspension that it requires replacing?

[Z4-VILLA]

looking for aftermarket someone said any headers for an M3 will work on a Z4MR granted the M3 had an s54 e46 engine. Also my front suspension suffered some while I drove quite spiritedly across a railroad crossing. The brief air I caught was exhilarating but the supension has me wanting replacement. I get bad vibration after 60 + mph.

Any e46 M3 headers will work on the Z4M Coupe/Roadster. As far as your suspension how do you know its the shocks/springs? Because its a vibration I would almost for sure assume it is not the shocks/springs. More likely alignment, unbalanced tires or maybe the hard landing or train tracks damaged one of the belts in the tires. Could also be control arms, control arm bushings.

hmmm I have to say I just recieved more help here in just five minutes than from my dealership. Im gonna have to look more in depth. And thank you for the clarification on the m3 header deal. I just wonder why so many aftermarket labels will say they have "designed" a header for the Z4MR like its something like "ooh" special when its the same as an e46 M3? Definitely feel like I would have been had by say supersprint or one of those places. you know? but thanks so much. As of right now I still am looking for after market headers though. So if anyone can help my budget is 1300.00
I will wait as long as it takes Im patient till I see a good price. THankx

but honestly I bet would go for SS headers if I had Loot like that :-)

Try the OEM M3 CSL headers, they say they are the best but cosy mucho $$$$....The next best alternative are the Active Autowerke Gen IV headers and they also cost lots of $$$. Wait it out until you can get a good deal.

[F360C]

You can pick up alot of headers for you budget or well below your budget. Here are a couple options you can go with prices. The prices might not be totally exact down to the dollar as I am going off the top of my head.

JVT (ebay headers.. what I run): $100-200
Bimmerworld: $699
Bavauto: $700
Agency Power: $900
Active Autowerke: $1300
SuperSprint non-stepped: $1100-1400
SuperSprint stepped: $1800-2400

Yea AA headers are the same design as the CSL, only difference is the welding and thickness of the metal (as well as have secondary o2 and egt bungs welded already)

Some of those prices are a little wrong, bav auto and bimmerworlds are basically ebay headers. AA headers cost more then that, the SS stepped headers will be less (once they are complete with this new revision). and the non step are more.

<Nevermind>That jolt could have broken your passenger-side motor mount bracket as well (common failure point on ///M coupes).</Nevermind>
Your avatar is a coupe but I missed your auto description which lists roadster. To my knowledge, this problem hasn't affected roadsters.

[Z4-VILLA]

thanks so much for the info. Very useful indeed.

[Z4-VILLA]

I am definitely going to wait for something good as far as headers go. However the Agency power headers for th 99-05 m3 seem to be quite good. As I recall my buddy had this on his M3 combined with an eisennman catback exhaust and it was impressive in regards to sound and power

Dealership opinions are a hit and miss. You might run into a tech who knows what he is talking about, or into one who is fairly clueless and is guessing. In the latter case, their recommendation can cost you significant $. There is a chance you might have bent a rim considering the impact. A simple test would be to swap in some wheels you know are straight and true and see if the vibration goes away.

[Z4-VILLA]

this I will do.
