I currently dropped with Eibach and I was wondering if I can get 255/35/20 and 285/30/20 combo with no rubbing issue or minimum rub.

Andy said it's not going to rub but I just want to make sure.

thanks in advance

 

Yes you will rub on dips and bumps etc unless you introduce some more -ve camber (but that will wear out your tires faster)

 

What is your offset? You will prob rub in the rear . . .

 

Agreed, will be a tight fit. May need mods or neg camber to clear bumps/with people in car.
