Lightweight 15" wheel/tire recommendation

I have '19 SI. MAperformance has a small brake kit that says it will allow the SI to have 15" wheels. Tirerack recommends 15x6.5 wheel with a 215/60R15 tire. The stock 19" tire width is 9.3" vs 8.5" of the 15". Will that hurt the handling a lot? Could anyone here suggest affordable lightweight 15" wheels/tires? Thanks!

Sorry I don't have any actual useful input but why do you want to run such a small wheel on the Si?

It's my daily driver, I want the weight savings, cheaper tires and better ride quality.

17” wheels are pretty light, a good set of 17” wheels with 235/45/17 tire should be 38-40lb.

A curious solution to a problem I didn't know existed. Most of the time, folks are looking for larger brakes to better handle heat or for appearance. But you've decided to go the other way. In fact, the only reason I could see why folks would want this is if they are building a "drag car".. small brakes.. small light wheels for acceleration, but you seem to simply want to improve your street ride.

Of note, 60+ series tires will make the car handle less crisply.
Of note, narrower tires (215 vs the OEM 235) will also make the car handle less crisply.

I would likely consider lightweight 17" wheels and keep the OEM width/offset.
