I use to autocross my 2018 M3. We recently traded it for the Highland 3P. I had completely built the suspension for ASP class. The season is starting so I wanted to get these parts listed for sale. You will notice that since of the arms/links have wheel weights. This was me attempting to stay within the spirit of the rules and make these parts weigh the same as the stock parts. They come off, I just don't have the time.
