I like how these are very E90 M3 like wheels. I haven't seen these particular wheels on a 335i and was curious how rare is this setup from the factory? I'm not in a situation to buy now but eventually would like a 335i in this configuration. How common is it?

403M is common on F3/4 series. there's peeps selling them in the classifieds below, all the time. they're a bit heavy.

[Stopsign32v]

Good news, thank you! Anyone know what their weight is and size?

find your wheel and convert kilograms to lbs

18x8 +36, 28.9lbs and 18x8.5 +47, 29.2 lbs. tires are 24lbs and28lbs. 53lbs, 57lbs total weight.

While they are common in these forums, they're pretty rare to see out in the wild. I think they're about 5 lbs heavier on each corner which is more significant because it's unsprung rotational mass. In general 19" wheels aren't common on the 3 series.

The most common M Sport wheels by far are the 400m wheels. I almost prefer the sport line wheels (397) because those are machines and have their bolts hidden a little. However the 397 are even (much) more common than the 400m wheels.

5lbs extra per wheel is significant. But I do like the look of them!

19" 403M wheels look great but are quite heavy. 19" 401 Style wheels are even heavier at 30 lbs each. I still have a set of 4 401 Style wheels with winter Pirelli Sottozero tires for sale.

These 403m's have come on almost every M Sport F30 since it's release. Either 403m or 442m. 403m had many too spokes for me, sold em

[bimmer456]

I have 19s not sure how much they weigh.

[Stopsign32v]

Since I want to go 19 inch wheels maybe these make sense. Good winter wheels/tires and spares.

While we are on the topic...

What is considered a "decent weight" for a wheel on the F30?

NOT ultra expensive aluminum wheels... just your run of the mill, OEM or similar wheel.

Im beginning to wonder if mine are considered "heavy" as well but a little unsure of what the definition is.

I realize this is subjective/variable depending on many factors but... more interested in peoples opinion for our platform.

As mentioned those are the 403m wheels. They were the optional 19” upgrade wheels, not part of the standard m-package. I don’t think I’d go so far as to say they’re on practically every m-sport car since release since they were a separate option. I almost never see them on the road, although YMMV.

Here’s a closeup of mine - IMHO they look great with m-sport brakes and EBII paint.

20-25lbs is average for 18-19 inch wheels. Anything sub 20lbs is "light weight".

Damn, 405m are 24lbs and 20" in size.

[cfm56d7b]

20" 405M wheels are one of lighter BMW OEM wheels: only 20 lbs.

Nice link!

Looks like Im rolling with 52.51 lbs on all four corners... good info to have when making decisions on wheels and tires in the future.

Would definitely be interesting to see if a set up in the mid to high 40's would actually make my car faster. Both literally and feeling wise.

it does...that's why i'm on 18" volk g25 with continental extremecontact sport. my wheels/tires are 42lbs and 45 lbs.

light tires have the greatest impact because it lies farthest from the hub. next is the barrel being either forged or rotary forged, then the wheel face with low materiel(i.e. thin spokes) tapering narrower furthest from the hub and also proper widths and offsets to avoid having extra material.

kinda anal, but i consider this in addition to appearance. the bottom line is it costs to have it light and strong.

I have the exact same tires but DWS 06. They are 25lbs a piece. Sounds like the Sports a bit lighter. Assuming because they are a summer versus the all season DWS 06.

Ahhh.... the benefits of a year round warm/hot climate!

Love my Conti's and will definitely look into the Sports when I am able to afford a dedicated summer set up!

Car and Driver had an interesting test of a mustang with CF wheels and compared results to standard wheels. The results are pretty eye-opening and worth a read for anyone who thinks about the weight of their wheels.

That car is priced high too. Little to no options other than M-Sport it appears.

I always try to aim for wheels that are no more than +2 lbs from the diameter. Of course it depends on the width, but my forged 18s are 18lbs each. I wouldn't go over 20lbs on 18s and 21lbs on 19s.

Appreciate the insight.

Are there any OEM 18's that you are aware of that fit this bill?

That's ultimately what Id like. Very happy with my current OEM 18's but they weight 27.5 lbs each.

20lbs might be a dream but I would love to be in the low 20s with my next set.
