Has anyone installed one of these?
I have one of my F56 lower arms a little bent.

I have the NM Adjustable control arms installed. I don't know if I'd trust those eBay models. They look like they're one size fits all and I don't believe that's the case. I remember when shopping /researching for mine I wanted to go with the Helix version, but their 3rd Gen arms were still in development. They were different from the 1st and 2nd Gen or they would have sold me a set they had on hand. On the NM site the R56 and F56 have different part numbers.

Just out of curiosity, how the heck did you bend a control arm?

We've been using the Megans as they are very cost effective and fit great.
