• Please remove 12 screws from the rotor assembly.
• Please mount the rotor assembly onto the hub by using the 12 screws provided.
• Please make sure ABCD are all in the same distance by using a calibrated scale. (The tolerance can not exceed 0.05m/m) (Shown as attached photo)
• Please tighten the 12 screws and torque them to 14-17 N-M.
• Verify that the tolerance of ABCD is within 0.05m/m.
• If the tolerance exceeds 0.05m/m, vibration will happen while the car is moving

Because OE lower control arms might be manufactured by different OE manufacturers, there should be tolerance. In order not to conflict with wheels, the clearance between brake system and OE lower control arm is small. Due to this reason above, when you install our brake kit, you may meet the condition of conflict your lower control arm with our caliper.

There is a solution as below: Please put the same thickness washers on the OE caliper mounting and OE disc mounting; please see pic A and B. Please note the washers should be the same thickness and number as well. Afterwards, please fit our caliper and disc, the problem shall be settled.

 Remarks: You could use our washers in a tool bag or you could find washers in same thickness by yourselves.
