Below Speed Limit - you might want to edit your original post - pretty sure the half inch wider thing is wrong per my post above, and since most aren't going to read the whole thread, this is going to further that misinformation.

Unless of course this half inch is verified somewhere?

What is interesting, though, is that the 601M wheels use a different offset in the front - they use a 32mm offset, rather than the 34 the 343M uses - so the CP front wheel pokes out 2mm compared to non CP.

I agree with B-1, I think 601M's are equal in appearance appeal to 343M, I just personally like the 343M's a bit better since they were the launch wheel for the F10 M5.

I don't know if anyone here has ever picked up a 343M with a tire on it, but jeezus is it heavy. The 343M's may be forged but they aren't exactly light either. The weight of the 601M's makes it a little worse, it's true, but as other have pointed out you are not going to notice a 23lbs weight difference on the street, and maybe if you were Randy Pobst or Chris Harris, you'd notice the difference on the track.

The last thing I will say, again which others have pointed out already, is the longevity and durability of a cast wheel, especially on M cars. I don't know the long history of every single wheel ever specifically designed for an M car, but I'd guess that the majority of them were cast wheels. I have only known a handful of people who actually cracked their stock OEM Cast M wheel, and in 99% of those cases, they hit an extremely bad pothole extremely hard. So just avoid potholes and you'll be fine with the 601M's.
You won't notice the weight difference, but that's besides the point. The same can be told for the 15hp or the extended torque in the rpm band, but we still pay for it don't we It's all about paying more for a $7,300 package and getting something inferior. Usually when companies come up with these expensive packages, they are considered "upgrades". These wheels are not upgrades.

Let me turn the question around and ask this, if both of these wheels were offered 2 years ago with the first M5, one being $1200 wheel and other being $800 wheel, and all the information in this thread was known back then (one is forged, one is cast, one is 5.5 lbs heavier, etc), do you think all these people who now have the 601Ms would still go with these wheels? I highly doubt. I'd say 90% wouldn't, nobody in their right mind would, unless you are seriously into the style of it. The reason why people go for these wheels now are two fold : a) They don't know all of this and they assume because it's the competition wheels, they are better or b) They get it because they want everyone else to know they have the competition package, the latest and greatest.

Competition in its name implies faster/better/stronger, and these wheels are complete opposite of that.

The fact that they won't be as durable is secondary. You are right, BMW's cast wheels are not terrible, but then I don't think they made 20" cast wheels until now. For all intents and purposes, these wheels have been in use for the past 6 months, not 3-4 years. We don't know how durable they will be.

Also remember that it's not just cracks, but the balancing problems that I worry the most. Cast wheels are a lot easier to get out of balance than forge wheels because they are softer and not as rigid.
I went with the 601s because I preferred the look.
I went with the CP because of the better steering feel and exhaust note.
I made the decision with my eyes wide open, and it does irritate the hell out of me knowing that the 601s aren't forged. BMW should indeed charge less to those who opt for the 601s.
I called BMW to complain and BBS to inquire. BMW confirmed 343Ms are forged and 601Ms are cast.
BBS confirmed that they manufacture the 343Ms via e-mail I believe (as they had to research it).

I want the best so it was very hard for me to forgo both 343Ms and CCBs.
But in the end we are talking about a large, heavy luxury sedan and not a race car so I went with what I liked the best and made most economic sense (standard brakes).

Early on I hated the 343M wheels but now appreciate the rawness of them. They seem to more consistently "match the M5s design DNA" (to steal these words from a fellow forum member whom so eloquently described the 343Ms in an older post).

Here's the real Question:
Drive CP M5 with 343Ms and CCBs for half a day...
And drive CP M5 with 601s and standard brakes for other half of day.
Under NORMAL yet aggressive driving is there a discernible and valuable difference in overall handling between the two cars?

Time will tell the durability of the 601Ms. As I've said in another post, I had 20" cast Style 32 wheels on my '06 750i that I drove daily for 3 years (hit many, many nasty potholes) without out any bending/balancing issues.

Correct me if I'm wrong, but aren't the 343's a no cost option with the Competition Package whereas they are normally a $1200 charge without the CP? I am not just saying this because I have the CP, but I believe there are several tuning and upgrades that collectively make the CP worth the $7300 and above all else I like that it is a factory tuning option. I have the 343's - but mainly because I preferred the look over the 601's.

I have 601's... They look much better in person and make the car stand out from other m5's ... After looking at 343's in person after having the comp wheels, I'm very happy I chose the 601's... I'm pretty sure all that nonsense of forged vs cast is a bunch of incorrect info... Makes no sense they would change the materials on wheels that are made for this car...Make sure you have seen the 601's in person before you make stupid comments...

I read most of this before I purchased but decided on the 601s as I had a 13' 550 msport and always loved the 343 but they look very similar to the 351m on the msport and wanted something different. The dealer had one identical to mine on the lot with CP and 343 I couldn't decide so he ended up finding one with 601 that was still on it's way over he could get so I had my choice but would have to wait a few weeks for the 601 car.

When I picked up my car they were sitting side by side and once I saw them in person I was very happy with my choice and do not regret it forged extra weight and all

So i was in the same dilemma with which wheels to choose. if the 601's were indeed a half inch wider at 9.5 and 10.5 i would've sacrificed the forged wheels for wider wheels. if they weren't wider i wanted the forged wheels. so here are the 2014 order guides it appears that both 343's and 601's are 9.5 and 10.5 at least if you order black 343's, the light color 343's are 9 and 10. so confusing


and the m6 order guide

I don't know if there are differences between US orders and EU / German orders but here in Germany all wheels for the M5 are definitely 9 X 20 and 10 x 20.
(for all M6: 9,5 x 20 and 10,5 x 20).

I suspect a misprint in the US catalogue.

The 433M's are CAST wheels!

9,5JX20 ET:31 36112284450 2 14.100 kg 811,96 €
10,5JX20 ET:19 36112284451 2 14.900 kg 901,50 €

BTW, these wheels are only for M6 and not allowed (by BMW) for the M5 because of the bigger width and different ET (Offset) ! (I know because I wanted them to put me the 433M on my M5. It was not possible.)

This is an excerpt of the German M5 catalogue.
We only have 9.0 and 10.0 !

And on the wheels you find the same numbers.

Are there really differences between German and US original BMW wheels ??

Anybody?

Not at all !

A good decision in my opinion. When I saw mine for the first time, I loved them at once. And believe me, you will, too !! The design is gorgeous !

But as always, everything is a matter of taste...

Also I am sure it is an optical illusion or maybe offsets? but for some reason CP with 601 appears to sit lower than CP with 343 IMO

You won't regret the 601 for sure

haha.. your not the first to change their mind on features and options on this car. sometimes voicing your concerns "aloud' on the forum is the best way to fully vet your assumptions.

You are going to love the car whichever way you go.

I have both sets. The 601 CP wheels as a winter setup and the 343's for summer.
Like most euro boys, I prefer the OEM look, so I'm perfectly happy with both sets.

Obviously, the comp pack wheels should be forged. But the roads are well maintained where I live and seriously: who can tell the weight difference in non-track conditions?

The wheels pictured here are mine.

The cracks, and that's definitely what they are as you can stick your finger nail in them and a pin in about a 1/2 inch) are NOT cracks caused by use. The cracks are a manufacturing defect, most likely shrinkage on casting.

I specifically asked BMW UK if the 601M wheels were cast or forged before placing my order, this was before much was known about 601Ms. I said that if they were cast then I would order the 343Ms, but if forged then I preferred the look of the 601Ms and they are the most visible aspect of the CP. The answer came back that they were forged. Having removed them to fit my winter wheels it was obvious that they were cats and not forged so I raised a dispute. BMW UK still insisted that they were forged so I asked them to get conformation from Germany. The answer eventually came back from Germany that the wheels are cast. BMW are now supplying me with a set of 343Ms.

The figures quoted by the OP are correct, the 343M wheels are about 22lb lighter than the 601Ms and should be considerably stronger. I find it extraordinary that the CP wheels are inferior to the 343M wheels in every way and that you can choose at the time of order either at the same cost when the cost of the wheels themselves is significantly different.

The 22lb difference in weight is more significant than you might imagine, it's not like having a 22lb weight in the car, this is rotating unsprung mass. 22lb will make a difference to ride quality and acceleration, probably at least as much as having an adult passenger in the car.

When ordering the car, do yourself a favour, get the 343M wheels. If you want 601Ms just buy the wheels from the parts department and sell the much more valuable 353Ms!

The 6 series 434Ms are even heavier than the 601Ms and are also cast.

Why is nobody considering the 345Ms? How much heavier are they? Esthetically I still like them the best (wondering if BMW every will come out with a black version).
