This would suggest that the rear drop is indeed a fair bit more than the front and its not just our imagination. I was under the impression that the drop would be equal all round?

All points towards there being a technical reason why the front is not dropped the same amount on an xDrive. At a guess, BMW had to increase ride height to get to the Lobro joint 'sweet spot'. Who cares as long as it rides OK?

Would bother me a little if it was ass down, would prefer the front\rear balance to remain close to stock but lower. Perhaps tweaking the springs to raise the rear by 10mm or so might give a nicer look, although I wouldn't sacrifice handling improvements for that.

Forged wheels or engine upgrade?
Quote:
I realise they would improve overall handling, braking, cornering, provide less wear and tear on suspension system, stronger, look better ( personal preference I know ), lighter by at least 18Kg overall compared to the equivalent cast alloys by AC so therefore improve performance. Including theoretically, better power transference to the road from the engine also. The science boffins at AC also talk about reduced gyroscopic forces multiply this reduced weight effect further improving performance. AC Germany don't provide exact figures and I can't find anyone else who does. But i did notice the difference in performance just with the springs, sharper, more zippy, as though the car had lightened considerable..so.... The question is, How much difference would you feel? And how much more is the weight saving over the standard M Sport 335d F30 wheels we all have opted for? More than 18kg I would think as they look as though they have substantially more metal on them. Engine upgrade with AC or their forged wheels? Any thoughts please? |

@Lorcan - what's the view on spacers? I'm hoping to fit mine this week for cosmetic reasons but should I expect handling difference with the springs setup?

We don't sell spacers for use with standard wheels so I can't really comment on them. |

Lorcan, thinking of having the springs fitted and wondering which dealer you would suggest around West Yorkshire. Bought the car from Sandal at Wakefield, so would probably go to them unless you have a better recommendation.

They are happy to do it, Sandal Wakefield quoted 620 all in.

However, BMW actually use quite light wheels these days, and the M405 (for example) are flow formed and very light for their size. Probably better bang for buck than ACS wheels? If you are going down the wheel weight route, then make sure you get serious about choosing light weight tyres too, which means ditching Run flats. |

At this I'm moment trying to get actual weights of the current wheels 19' M star spoke style 402M almost all of us have on our 335d from BMW UK. The local dealer/service dept could not help. I prefer run flats due to the safety aspect, but i'm aware of weight and comfort benefits returning to non run flats. I don't really wish to go up to 20" Double spoke style 405M as all reports I have heard say they look great, but the ride is very hard. Which I don't want. Otherwise I would probably go for them as I would get some discount from the dealer also. Would be interesting to see what they weigh though compared to the ACS ones. We will see :-) |

Thanks Lorcan, rang today and just my luck Lee on hols for the next couple of weeks. Had a quote sent through which was more than the £620 quoted to Ozwol but I am sure they will come down lower.
Ozwol, many thanks for the heads up on cost. Presume the £620 included VAT? Did you have it done? |

I decided against in the end as (for me) the car is absolutly fine with stock suspension. Tbh if i didnt know from the forum it had se suspension i would never have known from the ride. |
