19s vs 20s
If you're trying to avoid the thin sidewall, you could run a 255/35 up front and a 275/30 in back without throwing codes. I don't know if a 285/30 would fit in back.
1. Get forged rims over cast. Cast rims are heavy, and can crack a lot easier than forged. If you get cast...your car will be slower and you will notice.
2. Try to avoid running 25 series tires on the car. You will feel the road much more (depends upon tire type and compound), and every bump or pothole will make you cringe. You can't avoid them all, I sure couldn't and had 2 cracked rims. In half. I am back to stock now...
3. Make sure the fitment and speedometer are correct and true as possible.
