Is Four-C worth it?

Hello Forum, I have read the entry-level thread to Four-C, but wanted to get a current opinion of you: I’m basically concerned with the unsightly effect that with my D5 (163PS) the traction on the front wheels leaves a lot to be desired when speeding up. Now I think for my next V70 (with 185PS or 2.5T) about ordering with four wheel and / or four-C to eliminate this effect, among other things. Thanks for your tips, Sebi70
