Too grippy & wide tires for stock power level and staggered tire setup both are wrong if you want to keep character and balance stock had. Best (and also cheapest) bet would be keep using stock sized tires. Tinkering with suspension changes/upgrades .. why fix thing you made worse trying other ways/upgrades instead of reverting that mistake in first place? Imho
this thread is worth reading.
I wouldn't also think that upsizing wheels is right if you care more about handling then looks. Stiffer sidewall tires at right pressure will help more sharper turn ins then one inch bigger wheels. Unless you must have (doubtful for daily driving) big brake kit (many of which fit fine in 17") that is not cleared by 17", there is no reason except looks to change rims to bigger ones, that will be heavier, slightly robbing acceleration, adding weight (i
know that there are few lighter 18" then stock. But 17" of same type will be even lighter anyway), making suspension work harder. Pay to make worse thing you care for?
