Full M3 parts list with part numbers

[SHeap]

The following is a list of all the components that are interchangeable from an E9x M3 onto our E8x's.

This list may come in useful for anyone who plans on doing a 'full' M3 suspension change at some point...

Obviously when it comes to ARB (FSB) it's up to you whether you go E92 OR E93 you don't need both, they're both listed to show you the available options.

If this list helps just one person and/or prevents another "what parts" thread then it's been worth while

(Please note I have included a couple part numbers etc for fixings but there are more, you can always re-use your originals but if you're replacing everything else why not do the lot :P )

If I have missed any parts please feel free to let me know

Nicely done!
That's pretty much exactly what I bought for my car (except I didn't do the rear).

Pretty sure you only need one headlight adjuster rod (37142283867) though.

You might, I don't have xenons (atm ) so don't need one and as such haven't looked into them too much.

I take it it's just one rod that works both headlamp adjustments electronically then and not one rod per side?

Yupp, only need 1.

heaps of rear parts

i'll grab the numbers and post them here :/

i'm pretty sure HPA used to sell a complete kit for it... rear camber link is one, that needs an M lower shock mount.

Yeah there are a few parts I've intentionally left off to prevent confusion etc.

The rear camber/toe link doesn't fit unless you have M3 shocks. HPA and a couple of other companies do their own version though which do fit when running standard shocks or a suspension set up designed for e8x chassis.

if you were to install the M3 lower shock mount you'd need to find shocks for an M3 not E8x, I'm not sure if that'd be a good move :S

Also whats it like length wise compared to standard baring in mind drive shafts etc...

still worth listing (maybe separate heading?) as well as the 'direct fit' parts

but nah, HPA just offers the m3 lower shock mounts in the package for their coilovers.

nah, if you have coilovers, you just need the lower mounts (they screw on to most decent brands)... $120 for both for me! haha (BC racing's)

length wise identical, you can bolt on M3 driveshaft to stock hubs BUT i think the diff side is different (but the diff will bolt to the M3 subframe which bolts to the chassis fine )

it's all the same length down there TAKING INTO ACCOUNT the new mount... track on M3/1M is achieved through wheel offset, give them identical offset to non-m and track is the same, therefore DS length/shock length etc.

rack and pinion? strut brace?

Yeah true, I'll do some parts searching and do a non direct parts section as well.

I'm sure I saw HPA sell toe links, maybe not as part of a package.

This was really meant as a quick reference list for anyone wanting to do a M3 suspension overhaul hence only the main parts but I'll add any others people feel appropriate.

The list is not limited to suspension components if people want I can add the numbers etc for things like E46 Transmission mounts, F20 brake backing plates...

Reference coilovers etc and lower mounts aren't the bottom fixings on rear shocks different though? E9x have a bolt which runs parallel with the car through the bottom of the shock and carrier where as E8x rear shocks bolt vertically down through the carrier?

sorry if i'm over complicating it but just want to be certain so I can add it to the list and that if I do I can explain whats needed to do it properly.

I know pretty much everything is interchangeable but if you were to go as far as doing the M3 subframe you may aswell go M3 diff etc and do an entire rear subsection.

Has anyone actually done this complete conversion? - whats the damage? $$$

[Mr Kleen]

Unless you do the install yourself, figure at least one full day of labor charges. Plus you'll need a four wheel alignment immediately after. While you're doing the suspension you should also upgrade the springs and shocks so figure that into your price as well.

Wondering this as well (not including labor, just for the parts)

[flinchy]

off the top of my head, $1500-$2k.

[uberschnell]

Not a great idea to upgrade your rear ARB with an open diff. In general I don't think the E82 really needs a stiffer rear ARB. Better off going with higher rate springs.

for what it's worth I've done:

Front ARB (m3) ($312)
Front tension and wishbone (m3) ($590)
Front strut brace (modified M3 from HPA) ($400)
Meyle HD ARB links ($50)
rear Wishbone and Guide rod (m3) ($440 ECS)
rear toe link (Megan) ($200)
rear subframe bushings (prothane) ($175 and DIY install)

Dinan fixed camber plates ($200)
Wavetrac LSD ($1700 w/ install)
AST Coilovers / Swift Springs ($2300)

oh, and Brembo GT 355mm BBK ($3500)

I think my car handles as well as I would want it to. You can save a few $$ by going with alternatives (the rear links from ECS are TRW and OEM specs but cheaper) and the prothane bushings feel just as good as the M3 ones I had on my previous car but a fraction of the price and DIY install.

M rack and pinion is 1600 and another 1000 for install and alignment. Really worth it?

You can pick one up from a junk yard for $400 or $800-1000 for remanufactered unit. $1000 for install if you goto a dealer. I can have it installed for $100.

[SHeap]

First post updated with all parts and numbers as listed.

sfValley335i - Can you confirm whether a new power steering pump will be required?

Flinchy - can you provide a link to the rear shock mounts you are on about I am struggling to find them :|

"
This catalog entry is for the rear E9X M3 lighter weight aluminum camber links, all the necessary nuts and bolts, and the correct headlight leveling brackets needed for a complete conversion. These parts repalce the heavier steel camber links used in the E82/E9x non-M cars. One of the main advantages for switching to the M3 setup, besides the lower weight and greater strength, is the rear shock mounting style. The non-M setup captures the lower shock pin in a rubber bushing, which means less direct feel and slower reaction times. The M3 setup uses a lower eye mount on the rear shock, which a bolt attaching it to the camber link. This allows the shock to react more quickly to changing road conditions, it removes a potential failure point (aged, cracked rubber), and is lighter weight and stronger by design.


(E9X non-M on the left, E9X M3 on the right)
Note: Standard E82/E9X non-M rear shocks will not work with these camber links!"

[SHeap]

Just thinking out loud but if you were to do M3 camber links/ lower shock mounts would you not just need to get 1M coilovers instead of standard 135i coilovers as these would have the appropriate bottom connection?

Also as the 1M and 135i are in essence the same vehicle structurally and weight-wise the shock settings and spring stiffness would be correct (assuming non adjustable coil overs)?

[yawn]

Ah yeah, another thing too if you decide to fit M3 camber links to a 135i, not only do you need modified/M3 rear shocks, but looks like toe arms might need changing too. Ask me how I know lol...

[Greg FEightytwo]

33322283549 this part number on tunermotorsport.com says wont work with e82 non m? Can anyone confirm this?
