17" to 18" on e92 335i xDrive - Worth it? (functional, not looks)

I have an e92 335i xDrive coupe that came with the sport package, but only the 17" wheels. I've been toying with upgrading to the 189 18" wheels. While I do agree that the look will be much better, I haven't seen any threads discussing the 17" to 18" jump in terms of performance.

Also, I would be running Michelin Pilot Super Sports (non-RFT) on whatever I choose as my current Hankook V12's will be done for next summer.

The cost difference is about $230 for the tires alone. Factor in a used set of 189's for around $600 to $1000 depending on condition, shipping, and any straightening that may need to be done.

Bottom line, will I noticed that much improved handling and cornering for $830 to $1230 upgrade? Most discussions on this forum are about 18" to 19" jumps. I'd rather spend that kind of money on a new OEM M-sport front bumper, or an aftermarket oil cooler (car didn't come with one) + used Cobb AP.
