Part numbers for the arms are B31.10.8.053.331 and 332

It's quite hard to tell if the Dinan ball joints were worth it actually. Because I did a bunch of changes together it's impossible to tell if they've made the steering better or worse. In hindsight I wouldn't have done it, and would have only done the drop and the arms and then reviewed.

I did consider the Dinan rear suspension link kit too originally but the feedback from my suspension guys was that it wasn't particularly impactful on this platform.

So unless I got lucky, the control arms that come on the LCI Competition are the MINUS. My car getting ready for this track season and I decided to make this mod and ordered the MINUS. Turns out the MINUS is already on the car.

Where are you for camber and what do you recommend? I am at -1.5 front on a 2018 Base, lowered with H&R M5 springs. Should I try the “minus” arms? All street driving so far but I should have time this year to get on the track.

I’ll let you know the final camber number Friday still waiting on tires to mount the new wheels. We were shooting for -2.0 so hoping that happens. I track pretty heavy and I felt camber was alway lacking and one of the biggest down falls for my set up; along with rotors. Check the part number of your current upper arm and if it’s not the same I would do it.

Good info thanks

I was about to order the MINUS arms, but will check the part number on my car. 2021 Comp.

I seem to remember my stock front camber was around - 1.3 degs....so perhaps I don't have the MINUS arms. Interestingly the alignment printout shows the range of -0.5 to -1.5 degs

The ones on the car have the same part number printed on them, and the same offset rearward and inward as the camber correcting arms I ordered from BMW. I also been over 160 numerous times and didn’t get the M package for the governor taken off.

I doubt BMW just hooked me up so maybe the LCI Comp came with a little extra

Before I flash tuned, I saw 164 indicated on my 2018 non-Comp. At around 100, GPS and the speedo are within 1-2 mph, but maybe the speedo becomes more optimistic at higher speeds. I have read that the limit for sustained speed is lower than for the peak. Maybe I peaked at a real 162 with 164 indicated.
