Alignment pins: to pull or not to pull
Im about to install Swift springs on my ZCP E92 M3's factory EDC shocks, and considering removing the alignment pins. I had my car aligned back in August and the front camber specs are -1.6 left and -1.3 right (completely stock ZCP suspension). The car also has a very slight right drift that the alignment guys weren't able to correct saying the front camber is not adjustable.
My M3 is my only car but I don't have a daily commute so I'm not that concerned about front tire wear and would like having better turn in since I plan to start doing HPDE. So should I pull the pins or would I possibly end up with too much negative front camber for a street car? Im also assuming the slight drop from the Swift springs would also add some neg camber? Thanks

If you are going to be doing HPDE and are already messing with the suspension, just get camber plates. They'll pay for themselves in fewer tire purchases. That alone is worth it. It will also give you a ton more grip in the front and make turn in much better too.

Pull the pins. Its easy. You wont end up with too much negative camber even with lowering springs. I think I have -1.6 with pulled pins and the mild H&R springs. Never had any excess inside tire wear.

Pair your springs with camber plates since the suspension is already coming out, as mentioned. Pull the pins, obviously, too, and get a nice alignment and sticky tires. Big smiles after.

Get camber plates when you decide to get coilovers in the future. (Also getting camber plates now may not be the right size for coilovers in the future) |

+1 on camber plates. Negative camber -2.8F is perfect for our cars.
You can change camber yourself before and after your events.

If I pull the pins how much more negative camber will I gain atop of my current camber? Currently -1.6 left and -1.3 right And do the camber plates reduce/negate the drop of the lowering springs?

Pull the pins if you track. Don't if you don't track.
I pulled the pins and got -2 degrees camber. This resulted in excessive inside edge wear during daily driving (Mich PSS). I readjusted to -1.5 and only plan to run more -ve camber for track. |

FYI I pulled the pins and have Swift Spec R springs. I'm at -1.8 front camber. That's perfectly fine for a street car and while not optimal, isn't the worst for track use.

Swift springs installed will usually give you near some negative camber just from the car being lower. |

I have mine pulled on stock suspension.
If I were you, I'd definitely pull them, if nothing else when you get the car aligned you can use the adjustment to make the camber even on both sides, just because the pins are removed, you aren't forced to max the camber, although I would because I think you'll still barely get to -2.0. If you set your toe to 0.0 or close to it, you will not see excessive inside tire wear. Cheers, Jeff |

Why don't you go to the track first before doing anything. Then, if you like it and want to go back, you can do the Swift Springs and camber plates. If you don't like it, do the Swift Springs and optionally pull the pins.

Nope. With the pins pulled, there is some leeway to move the strut top mounts around a bit for a bit of camber adjustment.

Would be hard pressed to say that getting -.3-.5 more neg camber is something you would be able to feel by pulling the pins. You start feeling a difference once you subtract at least another -1 and the chassis is very happy at -2.8-3.0. I keep mine there for daily driving as well. Also you want both fronts to have the same negative camber..much easier to achieve with camber plates.

A little late to the party, but anytime you adjust camber, it directly affects your toe setting. When you add negative camber, you make the toe adjustment move OUT. This is why you possibly could get some "camber" wear when it's actually a bad toe alignment. It's a small amount of negative camber to be honest.
