Talking What is the biggest brake front rotors that could be used on 2015 f sport awd?

Hi Guys,
I have 2015 GS Fsport AWD and I am about to change all for rotors because there look of rusty now. Does anyone have any suggestions on a good performance band and what largest size rotors I could install on that model and can you swap out the front rotors for the bigger rotors from the RWD Fsport GS?


Thanks

It doesn't work that way- you'd have to change out both entire front caliper assemblies as well at the same time in order to accomodate a larger rotor size. So you're basically turning something which is a 300 something dollar DIY job with OEM parts into at least a 2x as huge dog and pony show for likely little benefit. If you're not tracking the car or driving it super hard all the time, you're never going to see the benefit, IMHO.

Like the other guy said unless your tracking the car, Big Brake kits/ rotors are purely cosmetic. No real difference in performance for street use.

If you change the 13.1” rotors on your 4GS to a larger size you also will need to change your calipers because the stock calipers will no longer fit that larger rotors. I just did the RR racing BBK upgrade on my AWD 4GS, the upgrade moved me to 14.1” fronts and 13.6” rears. Unless you drive your car really hard like I will be doing you won’t reap the benefits of having larger brakes other than for asthetic curb appeal. The front kit is roughy $1,400 from our forum sponsor.

yes you can swap in the RWD front rotors but will require the calipers to go along with them as folks here already said.
they should fit under 18" wheels.

may I suggest you have your rotors resurfaced and get some nice brake caliper paint and some Lexus heat resistant decals and go to town!
