These are from the alignment I had my dealer do as part of delivery. I had to type them out because the printout doesn't scan well. Anyway, they are actually generic to the E9x 3 series. The only difference is that you can get more neg camber in the front of an M. Mine is set to -1.3(left) and -1.2(right) with the guide pins in place (incidentally the max I could get from my 335 was -0.5 and -0.7 with the pins out). It handles very well, but I am fairly certain it will scrub the outside tire edge when I autocross and I will end up pulling the pins, going for the max neg. camber (I have read you can get around -1.5) and setting the toe to 0 deg.
Front: Camber = -0.2 to -0.8 Caster = around 7.2 (this appears not to be adjustable) Toe = 0.03 to 0.20 Total toe = 0.07 to 0.40 Steer Ahead = -0.05 Rear: Camber = -1.6 to -2.1 Toe = 0.10 to 0.20 Total Toe = 0.20 to 0.40 Thrust Angle = -0.07 to 0.07 |

I only got -1.3 out of my front end.
So what's the consensus on who to buy from? Dinan TCKline ????? |

The dinan units are not really camber plates as they only add -0.7 degree, which is not nearly enough. |

Then why bother? There is absolutely no reason for more than 1 degree on the street, and unless you go at least -2.5, no reason to bother for the track either.

If you are aligning at a dealer, then no need to print out. If at some other shop, then I would print it out.

Also, if you go with the optimal -3+ for the track then you are likely to get pretty big oversteer, so then you need to adjust the rest of your suspension. I'd guess -1.5 - 2.0 would be neutral handling with significantly lessened shoulder wear.

Great thread!
I am considering the Dinan springs, and wondering if I should have the camber plates installed at the same time since the suspension will be pulled apart anyway. The two sets of tires I've used are worn out bad on the outside. With the extra -.7, one would get pretty close to -2 degrees after the alignment, which would be a pretty good setup I think like jakeo is saying. A couple of questions I can't seem to find answers to: 1. How thick are the Dinan plates? (How much of a reduction in the drop) 2. How much do they weigh? If anyone has installed them, please let me know. I called Dinan, but can't get a hold of anyone there, and my Dinan dealer has not seen any yet, so he doesn't know either. Also, I've read mixed reports on pulling out the pin--if the pin even exists or not on the E9X M3. So, does it exist? And, is the -1.3 max negative camber people are reporting obtained with or without pulling out the pin?

The camber plates are forged aluminum and result in a 1/8" reduction in the drop. They weigh less than a pound. If you max out the stock negative camber setting and add the plates, you'll end up with 2.0-2.1 degrees.
