I have a 2015 GS350 fsport with 65k miles.
I am looking at replacing my front brakes. The lexus dealer search tool is somewhat vague and doesn't really allow me to select the fsport model. If you have the part number for brake rotor for the fsport can you share? Also can you share your experience of your brake replacement? at what mileage did you change your brake pad/rotors. Thanks

 

If the brakes are not shuddering when you brake, you can safely re-use the rotors. If they shudder a little bit and your braking is normal, you can resurface the oem rotors. I believe Advics is the OE manufacturer of Lexus brake products. You can search their website for the part #, then but it on Rockauto and save some $$.

 

I am not experiencing any shuddering but the rotor formed a lip on the outer edge. I found one which i believe is the correct OEM rotor with part number 43512-53050. They're around $350 each.

 

The lip is normal. You can have the rotor thickness measured to see that it is still within specs. Most rotors will have the min thickness engraved on it, somewhere on the inside. I see this model has a left and a right rotor, that is, the rotors are not interchangeable. The Advics are $105 on Rockauto, plus shipping.

 

Thanks for pointing out the left and right rotor. I am tempted to just replace the pads and change the rotor the next time around. My pads are at 4mm with no noise or vibration.
