i have a 2004 M3 and have been recently thinking about lowering it just a little bit. i looked into H&R's and found the sport spring which lowers it 1.2 front and 0.5 rear which sounds about right for me. i was wondering what kind of effects, negative and positive, these springs would have on my car. i'm doing it mostly for the look since the suspension is already amazing, but would that slight of a drop make a huge difference in ride quality as far as comfort level goes? will it effect the performance of my shocks at all? i have 18" ///M rims and definately do not want them to rub. i know M3 wheel arches are huge, but does anyone know if they would rub after lowering? thanx to anyone that can help me out!!!
I have an e46 Alpina, with which I put 19" on. The 9" front ok but the
rear 10" have been a nightmare. I have had arches rolled to their
absolute max but still catch under race mode (ha ha !!!)
Anyway to answer your question, my car is already lowered at the alpina factory
not sure on what spec they are lowered to but look pretty tight. To lower
your meaty M3 would, I reckon look mean and I reckon they wont catch just lowering a little because the archers are already bigger on the M3.
Any way if they do, just get them rolled its not expensive and that would
def sought because mine was really catching bad before the rolling...
and its ok now for most driving conditions. Anyway hope this been helpfull
give me a shout if you want any more info. also got some nice pics if like!!!
Rolling the arch..... basically the inner lip inside your wheel arch
is rolled gradually upwards, creating more space between the tyre
wall and the arch. If you put your hand under the arch you can
feel this lip.
The tool that is used to roll the arch is custom made, and to acheive the rolling
it is necessary to remove a wheel and attach the tool to the wheel hub.
On the tool there is a strong plastic wheel attached to an arm, which is placed on the inner lip.
It is then moved from side to side of the wheel arch, each time having pressure
applied as it goes from one side to the other. Thus forcing the inner lip upwards. This is usually done also with the help
of a heat gun to prevent paint cracking (not usually a problem with beemers
because of flexy paint.... so I was told!!)
It sounds all a bit drastic but is quite simple.
As i mentioned before my arches on the rear needed that much rolling,
they are just about flat to the body!!!! Even to the extent of forcing the body
out a fraction!!!
Anyway hope you understand all that.
I put a pic in but since... I put some better mirrors on, those standard
