The Japanese refer to the perfect tire to fender clearance as Tsuda-Ichi (paper thin). The way to achieve the perfect Tsuda-Ichi style is to bend the inner lip on the quarter panels and fenders flat against the outside skin. The most unique and vital feature of the MAX FENDER ROLLER is that it is the only fender roller in the world that is convertable for use on extremely low cars. Most fender rollers are only designed for use on factory height vehicles forcing coilover equipped vehicles to raise up to stock height to roll the fenders creating extra work. The roller angle is especially suited to bending the lip as flat as possible against the surface to give your car the ultimate flushness. The urethane rollerbearing wheel is strong enough to bend metal yet soft enough to prevent paint damage on most cars when used in conjunction with a heat gun. The roller is a must for fitting low offset wheels. For cars utilizing standard offset wheels, use MAX Tsuda-Ichi wheel spacers and the MAX fender lip roller to create that hella-flush JDM look on your car. Update! The first fender roller specifically designed for lowered cars is already in its second generation with many improvements making this the best wheel fitment tool money can buy
