Large wheels + lowering will usually always = scrubbing, unless the guards are already pumped from the factory. The fully sik uleh's have methods on fitting those large, oversized wok rims on their fully fully fully fully omg omg cars. It involves rolling the hell out of the guard, but if it's the liner that's the main issue, you'd need to box your guards a little as well (which involves plastic welding, an interesting niche trade). You can always raise the height, but I know how it feels to have your ride low. It does look the tits. Also you could always put 19's on there, they'd still look somewhat big and you could maybe lower it even more then. They'd be your options though, speaking realistically.
