I'm running Konig Tantrums at 17x7 (~+45), Dayton Daytona 225/45ZR, and stock suspension. With two people in the back, I do get rub occasionally in the rears on really off-camber turns. Other than that, they run fine. Just went on a really twisty-turney mountain run yesterday with the San Diego I-Clubbers and they worked beautifully with no scrub anywhere.
I am getting ready to put in the KYB AGXs with Intrax Sport Springs. They're supposed to drop the car 1.5" overall (right at the KYB max drop limit) but others are reporting only a 1.25 front and 1.0 rear drop so I'll have to wait and see.
