I'm strongly leaning towards a 128i M-Sport Coupe to replace my 335i M-Sport Coupe when my lease is up. This time around, I want to remove the stock wheels and runflats when the car is new, store them and put 'em back on for the lease return. My primary goals are to improve ride quality and lose some unsprung weight. A little extra grip/balance is a bonus.

I've come up with a few replacement options (please see chart). I'm thinking it might be a good idea to go with the first option (18x8" and 225/40-18 all around) because it would give me a little more front end bite and I don't need as much beef in the back with the N52 engine. I also threw in two staggered options derived from Tire Rack's site.

I'm open to all suggestions and advice. Thanks in advance!
