Default 2015 IS 250 Fsport, rotor replacement.

I need to replace front and rear rotors, which ones to you Guys recommend. I’ve been having issues finding aftermarket ones online for my specific model. also leaning away from slotted/drilled. Just put akembono pro act ceramics for front/rear pads.

Check out R1 Concepts. They make oem like rotors as well as drilled/slotted for our cars and they are a forum sponsor. I’ve heard great things about their products. I bought their slotted rotors for my car but haven’t had a chance to install yet.

Running Akebono ProACT w/ Centric high carbon rotors (OEM style blanks). Having a great experience - about 1 year and 17k miles in and the pads look at least 80% new still, no lips forming on the rotors and best of all... way less brake dust and squeal. Small penalty with initial bite, especially if the pads are cold, but they work just fine after getting heat in them. 10/10 would recommend.

Don't know the size of your wheels, if they're 18" I would recommend getting a set of new GS350F front brake,
they are lighter, larger, better.

How about Centric? I haven't ran these on my Lexus, but I run them on my daily. I run stop tech slotted in front and Centric in the rear.

This is probably the best bang for buck. The lady has this setup on her '15 250 F sport (AWD) and zero issues.

Looks like those are for the Non-FSport.

Scrool down and you'll see the difference in the 2nd part of the part number.

Would need a whole new setup for that, new calipers. Easy enough sounds like after that but can't only replace the rotors.

The P/N for front should be correct, but please upload pictures of your current discs.
One look, we can tell:
https://jp-carparts.com/lexus/part_d...3&part=1271835
P/N for rear... should be 42431-30300:

How & Why is going OEM a "worst case scenario"? lol When it comes to brakes, pads, rotors, etc, IMO always prefer to go OEM, or at minimum Lexus recommended, but for lotsa other stuff don't care too much going after market parts. Anyway, once again, just a 2 cents opinion & preference.
