1M versus M3 stock suspension settings
I searched and it appears the 1M front camber is either the same as the 135 or maybe dialed a little more negative (one posting said about half a degree to a degree and a half negative, I think the half degree would be close to a 135 but a degree and a half would be a lot for a stock 135). I'm wondering how that compares to a stock M3. Anybody know? Can a stock M3 be set more negative than a degree and a half?
It seems like this might be part of the reason for the 1M being slower on larger tracks or it might just be wind resistance and more hp for the M3. Jim

The 1m loses out to the m3 on long straights due to m3 having more hp and better aero. 1m is actually faster than the m3 in the turns. Could it be even quicker in the turns with more camber? Absolutely.

I did some searching and came up with theses facts.
I compared a 1M and an e92 M3 ( both w/18" wheels) (both w/o active steering) for a 1M these are the Factory specs: Ride Height (front)...........600mm +40mm or -20mm Ride Height (Rear)...........592mm +40mm or -20mm Rear Camber...................-1*45' +0*12' or -0*12' toe (left or right)..............0*05' +0*03' or -0*03' Front Camber...................-1*20' +0*12' or -0*12' toe (left or right)...............0*05' +0*03' or -0*03' total toe..........................0*10' +0*05' or -0*05' The only difference for the M3 is the following front camber is..................-1*10' +0*20' or -0*20' The above numbers are in Degrees and Minutes *= degrees, ' = minutes everything else is the same.. what you shoud really compare are power to weight / track / total weight etc etc etc.. this is where the magic is..

Just asking, I am sure you had a technical reason for that choice. |

Question.
What is the maximum Chamber of the stock 1M front and rear can take. I am thinking of doing just springs and then matching the setup similar to my M3. More front camber than rear with 0 toe in front an 1/8 in rear. Thoughts? |

Good question. I've got a stock 1M and I'd like to get more negative camber into it. I'm hoping Vorschlag comes up with plates for the stock suspension since I understand that the stock setup is quite limited in terms of range of alignment.

Per my alignment yesterday I was able to get a max of -1.5 Left, -1.4 right up front stock. If you pull the pins you should be able to get more. If your springs also lower the car you'll get more still.

What tires are you running? I'm rolling over RS3 street tires up front with -1.5 degrees and would prefer more camber. If you run anything halfway sticky it'd seem like you'll be running too little camber, probably both front and rear?

I have the stock tires currently. In general you want more camber in the front than the rear. Most cases on BMW it is a 1 or .5 split.
Sounds like I need chamber plates to do a 2 and 1.5 split then.. |

So, anyone looking to return their car back to OEM specs can simply follow these specs? (Did you do this right after getting the car?)
Is there an official BMW spec sheet somewhere that we can all trust? I want to align my car but my shop (which uses a great 3D machine) doesn't have my car listed. I don't want him aligning it as an M3 or a 135i... (At the end of the day an alignment is an alignment, but I'd like to go back to OEM specs) |

Those alignment machines get updates thru out the year(iF they are paying for updates). So I would go back and see IF they have a 1M now listed now. IF not... I'd go to another shop. You should also be able to ask your local BMW for the alignment specs. I would think someone here would know the answer though.

Thanks Dackel. I checked with him a few days ago and he gave me the brush off: "Oh, we'll just align it as a 135i or an M3, no worries!" and I know I'm being OCD, I'd rather return it to OEM specs while I'm on OEM suspension.
He charges $60 cash vs $230 at the dealer lol. They both use the same machines. At this point I'm almost tempted to pay the difference at the dealer so that I'm not bothered by it.... I'll try giving the dealer a call first though. |

I would ask around. Maybe even see who all the racers go to in your area. Having an alignment done at a dealer is not a bad idea either. So long as you don't get a Tech who works under the motto... "Set the toe and Let her Go"!!! I have see those guys in action. Tell the tech you want a good alignment and you know(and can feel) the difference. A good shop will even let you sit INSIDE your car - as that will affect how the final alignment numbers come out. Thats when you know you have a good shop doing the job. Good Luck, Dackel

Hi
I have a stock 135i e88 2009 and I'm trying to get the alignment done although the places I have contacted want to use the thresholds from e87 and claim its the same for both models. Can anyone confirm this or send me the thresholds settings for the e88. Thanks Len |

Sounds like those shops don't have up to date SW for their alignment machines. Did you contact a BMW and ask them? Would be curious to hear their answer.
