Cool. Sounds good. I guess this is because you're taking the bracket into account. Cause IIRC, some people use M3 CAB on their non-Ms... or maybe I have that mistaken for another car. but it appears from what you say that both perform equally. What are the life expectancy on these? And would the fact that these prevent fore-aft movement would that put extra strain on the CA balljoints? Or negligible?
