Short answer, yes RS wheels will fit. You may have tire rub when you turn your wheel to full lock. As mentioned in another comment maintaining your overall diameter of the tire is important to keep the speedometer accurate.Oh damn, I didn’t mean to cause any arguing over anything. I’m a noob and don’t really know the correct terms for these things. But yes I was looking at getting what the RS wheels are like and if they could possibly fit the SEL. Thanks for the pros and cons of having these different wheels and tires.
I'd suggest an 18" wheel and tire package and if you like the style, ST wheels can be found cheap or you can run aftermarket wheels.
