I hope if they do the flares they make them cover the front of the tires like the WRC but of course smaller as mentioned. Rolled and pulled fenders fit over the 15x9 +35 and a bit more pulling I could possibly fit the 225 Hoosier R6 which is more like a 240 wide tire, much wider than the 225 Rival S or RA1 tires I have ran.
For the rear max roll and pull and trim the sealant off, change the camber, just to fit the Rival S or RA1, no way to fit the R6.
That said, the front is wider than the rear, not the other way around, an optical illusion possibly.
Rear flares to fit the wheel specs above without changing camber would require cutting the fender and metal liner and welding in a filler panel.

I would love to see real flares and a real vented hood made for this car, not vents in the wrong place, like I have that help a little but not likely much and flares that cover the front of the fenders like real flares should, not some fad flares with horrid aerodynamics.
