Camber Settings for Track
I just purchased a new set of Pilot Sport Cup+ for the stock 19 Inch wheels. I intend to track the car and not too sure if I need to set some negative camber in the car for these tires. After adjusting Camber, will it affect Toe? Do I need to do a wheel alignment?
Can I just set negative camber on the car without camber plates? Can this be done easily (DIY) or mechanic? If I need camber plates for front and rear, any recommendations? Thanx for the help!

there is not much room on the stock setup and to get the PCUPS to work properly you will need to run negative camber.
I think if you're staying with the stock suspension you can use the Dinan top perches to max it out a little bit more. I think you need negative 2-2.2 for those tires The rear I'm not sure anything is available yet but companies are going to being producing some camber arms You will need to align everything |

The dealer said they have to remove my front bumper to line up the lasers for an alignment on my lowered M3. If I take it to another shop is there specs somewhere I can have them set the camber to?

I could get -1.2 on the front both side without the pins removed. My BMW service refused to remove the pins since " it is not recommended by BMW". I feel some change, mainly because i was running neutral and positive on one side!! as a factory setup. Would like to find an independent shop to pull the pins out and max - camber.
I am not convinced by the Dinan camber plates. An extra -0.5 degree for $500??!!! |

Regarding the Dinan camber plates they are only $250, not $500 (unless that was with labor), and they add -0.7 degrees. They are not adjustable (and will slightly raise the cars front ride height, but are a fairly common way to cheaply add negative camber.

My understanding is that pulling the pins simply provides more "potential" movement. In order to realize that potential, you need to unbolt and slide the mounts, so alignment seems necessary after that is done as that is not exactly a precise operation, but someone should confirm this.

My mistake, I thought Dinan is selling not a pair but a single plate for $250!
I would not pull the pins and adjust the camber without realignment. |

The alignment pin in the shock tower support plate needs to be removed to get maximum camber. Just to be clear, this should be doable from within the engine bay by loosening the 3 suspension bolts on each side and pulling the pin out. No need to pull the suspension assembly out. Is this correct? On a seperate note, I am also planning to have the shop fit my Schroth 4-point harness in the M3. I have the E46 quick fit kit (from my old E46) but Schroth does not make a E90 quick fit kit yet. The plan is to use the E46 kit and use one of the front seats attachment bolts. Hope it works!

It's not turning out to be as big of a problem as I thought. If you run higher pressures (40psi back in the paddock), rotate, and flip once, you get reasonable life out of a set of NT01s (4 DE days). The camber curve is much improved on the E90 over the E46. Rear can easily do -2 degrees, which also seems to be fine.

I have -1.75 in the rear, and that proved to be too negative. Both rear tires were hotter on the insides than the rest of the tire (outside and mid sections were even). That's with about 41-42 psi hot on BFGs. I will have that dialed back. I have -1.95 up front with the camber plates, and that worked well with even temps across both front tires.

I just had springs installed and when they set the camber settings during allignment I ended up with -1.2 in front and, if I recall correctly, -1.7 in the rear.

Lucid, are you running this on the street? If I recall correctly, you are not running a square set up on the track. By not being square, does this have any effect?

I asked it in a different thread but more of topic here:
Does anyone running Dinan camber plates with the stock springs?? Is that lift up the front? Is it worth getting the Dinan springs?? I mean, for the track. |

-1.75 rear was too much. I was heating up the inside edges of both tires, and lost some grip, but that might have been a pressure issue. I had that dialed back to -1.4.
