There are definitely more big and tall sizes in 19’s than 18’s. But you’ll be limited to about a 285/30-19 up front. On 18’s, there are people running 305mm slicks on 10.5-11” wheels up front. 19” sizes are too tall to run that wide up front. Unless you want to run the Viper ACR’s 295/25-19

Which you should do. Because I want somebody to Guinea pig that tire for me

It’s not a fender liner problem so much as there’s a body seam in the rear of the fender that becomes a real interference problem with the steering lock you will frequently see on track and taller tires

The front fenders are plastic. So don’t roll them unless you like buying fenders.. The rears have no lip to roll so you’ll be pulling them if you need more.

But fender mods or even light massaging aren’t necessary with those wheelwidths. et20-25 up front and et30-32ish ought to be good for the best clearance
