How can you tell economy vs premium, and which rotors are you referring to?
Thanks
The RPT rotors are economy rotors. According to the description, they are machined for a maximum of .004" of lateral runout, which is a fairly loose standard. Most premium rotors, if they advertise runout, will be .002" or less. .004" is way too much for most modern vehicles.
"Lateral Runout & Thickness Variation
Our coated rotors come with a lateral runout of 0.004″ or less and a thickness variation of less than 0.0005", ensuring:
Less pedal pulsation
Less brake noise
An extended pad life"
