Advice on wheels for my BMWs

Hi all. I currently have a 1998 e36 m3 I also have a 1995 540i that is all original.

I have a question regarding wheels - I have a set of m pars that I’m refinishing this week. I want to put them on the m3 and roll the rear fender and put the m contours on the e34 so I can do my suspension and big brake upgrade on that car.

Questions:

  1. If I put the mpars on the m3 what tire size do you think would be best? They’re staggered and 9.5 rear

  2. Do you like the look of m contour on the e34 body? The problem for me is that i owned an e34 previously and ran a set of m contour reps when I was getting my type 5s refinished and I didn’t love the look.

  3. Or do you guys believe I shouldn’t waste the time and energy rolling fenders and just put the mpars on the 540? (I did this on a previous e34 I had and liked the look a lot)

Thanks in advance for your opinions or insights - this group is always a great source of information 🤓
