What sizes are the proper CSL wheels?

I guess you'll need 4 fronts as the M rears have a different offset to the non m cars and will rub (assuming the e90 is broadly similar to the e46). Photoshop them on to see if the max power side of you is right :P
Never quite sure with pics how things look in the flesh. May need to lean on a CSL owning mate to try it out
My car is sparkling graphite not silver though, and I don't have the msport body kit this dude has.
p.s. that looks like a normal CSL rear to me since it has the dish to it. These aren't photoshops btw.

More than welcome to pop round and try it. My wheels are a bit dirtier than that though
ps. awesome pics in the profile!

Might take you up on that. Barge needs it's legs stretched. Its a bit slow unfortunately
Definitely needs bigger wheels too I think. Bit worried about ruining the ride though which would rather undermine the purpose in buying this car to supplement the RS!
p.s. Not what they said in the pork forum
Apparently I've overcorrected. Funny, I thought I was heading for the turn in point of the next corner Anyway best sideways pics I've got so far, and what a surprise, taken by a friend, not the useless on track photographers! Edited by DanH on Thursday 28th December 23:11

What are they on there at the moment? 18s? If they fit over my brakes you could always take the car round the block with my wheels on - be interesting to see what you think of worn cup tyres in these conditions too :P
Hmm thats a good point. Only 17s so I guess they wouldn't fit over your brakes. Thought you had 2 sets of wheels for some reason.
I've experienced worn trackday tyres in this weather. Not great in standing water and I experienced a slight puckering when I unintentionally drifted up a slip road onto a motorway. This is why its good to have a practical car too. Heated seats are where it's at!

Dan, from the 3 E90s I've driven, you'd be right to have concerns over murdering the ride quality by fitting 19's.............
I drove a 330D Sport with the 18s on, it looked great but the ride was (to put it mildly) abysmal.
The same dealer rang me a few weeks later to say they had a demo car which had 17's on (the 18's had been put on another car) I used it for the day and was gobsmacked by the difference in ride quality.
The steering response wasn't quite as crisp, (but that actually made the car more relaxing to drive) The same dealer had two demos with Schnitzer 19's on, they looked superb, but two people who had driven the cars said they were "horrible" to drive !
You pays yor money and...............

Ride's pretty good at the moment, although after 18 months of only having an RS to drive around in (well also borrowed a e46 330ci a bit), anything feels comfy in comparison.
It does have the runflats, but by all accounts these no longer bugger things up as the e90 was designed around them, and on the 17s at least it rides fine. The geo seems to be out on the car though, so trying to get that remedied by the supplying dealer. Either that or e90s are meant to be camber following floaty and hard to place bastards. With the RS I just relax and let the wheel do its thing and whilst it moves around a lot, it tracks straight. The e90 tracks around less but actually trys to go for the hedge! Geo definitely not right...
So I guess I need to try some 19s on for size before committing! Looks really girly on the 17s though. I wonder if my speedo will end up wrong if I put the 19s on too? Not convinced that I can run the same rolling radius on 19s and have tyres with sidewalls.
Neil - yep, got the car in the end. The dealers were a complete pain, and its arrived with paintwork damage from the transport, geo out, and needing brake fluid changing in a month but apart from that I really like the car. Very comfy. Only downer is the styling is a bit anonymous in the flesh and it didn't have any uprated hifi in it, so I've bought a gin palace with a shit stereo
Need to rectify that! Hopefully the dealer will sort out my list of probs too as I don't think any of them are on. I spoke to BMW cust serv about the brake fluid required in feb and they said there was only a guideline of no servicing needed for 4k miles with an AUC car, apparently no guideline for fixed interval items. Which is ludicrous imho. Anyway see what the dealer says before I get too vexxed. Edited by DanH on Saturday 30th December 01:30

I've no experience with the e90 but I would be astonished if fitting 19's didn't ruin the car's behaviour. Surely comfort was the purpose of this beast, not style?
If you don't get the same rolling radius you'll knock the speedo out and affect gearing. washy said:

If you don't get the same rolling radius you'll knock the speedo out and affect gearing. Yeah it would accelerate faster though
I'm not willing to ruin the ride so definitely need to test this all out before doing anything.

Dan, I run my E46 330 D Sport on 17" wheels rather than the original equipment 18" MVs. The ride is way better, and driving at speed down poorly surfaced and badly repaired A and B roads the car is soooo much more planted and is bereft of all the tramlining nonsense that afflicted it with the 18s. The steering is also more weighty which I think improves it's feedback.
To get a feel for what the 19s WILL inevitably do to your car, ask to try an E90 330i Sport on the 18" runflats immediatley after driving your 17" equipped car. The difference is shocking IMO. I shudder to think what the 19s would do ..........
I agree the E90 does look a bit "limp" and undertyred with the 17s on, but that seems a small price to pay for the increase in ride quality and the ability to drive your car along what pass for roads in this country, without having to watch out for (and avoid) every pothole.
Apart from the ability to mount larger brakes inside them, the larger wheel diameters are undoubtedly the bean counters and stylists way of extracting more hard earned cash out of us (IMO). On the CSL and GT3 the 18/19s are a necessity, whereas on an everyday saloon they're a styling indulgence!!

Isn't it odd that modern 3s demand larger wheels to not look miss proportioned yet the dynamics don't support them. How do Jag XKs ride as they all seem to have 20" blingers.
Acres of rubber bushing no doubt helped in the old XKs !!
BMW seem to have firmed their suspension settings up at the introduction of every model. The best compromise I've driven was my old E46 328i SE Auto Saloon, It came with factory Sport suspension option (and seats) but with the standard 16" wheels. It rode superbly and handled excellently.
I definite case of the car being designed around 16" wheels originally and its dynamics benefitting from sticking with them as opposed to fitting the "fashionable" bigger diameter 17s or 18s IMO
