That's 20 front and back. I could maybe get away with 25, bit didn't fancy buying a set to try. The rear inner lip is quite big, my tyre would already hit it, should it ever compress that much.
I don't want my arches rolled. Not a fan of the idea, just creating a water trap.
I'm on Spoon springs, and will catch front liners on full lock, though mainly when there's a gradient too. Like my drive...
The back is deceiving, it's pretty much flush, bit other angles it still looks tucked.
Obviously your camber settings will affect this, I'm running half a degree neg all round.
