The backs use a different compound plus they probably only provide 30% of the braking force...

The pads I am using seem to be right on par with the oem pads...stopping power is superb

the reason why rears dont cake up is because most of the stopping comes from the front brakes

Yeah, 2 wheels cakin is enough man, we don't need all 4! Mine is becoming noisy too now, say going from 10 MPH to a stop.

So all I need for the swap are the brake pads, a clamp, pliers, brake cleaners and anti squeal right? The shims are reusable right?

C clamp isn't necessary, you can use a pair of pliers, put a paper towel in between the pliers and caliper so you don't scratch it up

The new pads come with rubberized shims, you don't need the old ones...anti squeal is optional as the new shims are rubberized...

The noise is mostl likely due to the amazing amount of brake dust built up in your caliper

Btw, I am at 250 miles with no dust!! Normally by that many miles I would be covered with dust and the rest of my car still clean

For the record, the same brake pads will fit 2013-2015 gs350 regardless of f sport or not, and regardless of awd or not....they all use the same caliper

To clarify further on the differences on the brakes....

F sport rwd has a 14" rotor vrs the 13.1" that the awd and non f sport
F sport rwd uses 4 piston vrs a 2 piston variant of the same caliper the other gs's use

The composition of the pad material may be different between the different set ups, but the size of the pad is the same...if you cross reference on akebono you will see the same exact pad is called for on all gs models...
All GS's use 4 piston calipers.

Okay, yea and my calipers are painted and I don't want to scratch them.

Until you need to stop really quickly!

Stop an inch short and there is no damage.

Needing an extra 5 feet to stop = ~$20,000 damage.

The front brakes are responsible for 75% - 80% of the braking. That is why the front brakes are larger and always wear quicker.

Do you want to be able to stop quick enough to avoid an accident entirely...or just get slowed down enough before impact that the damage hopefully doesn't cause injuries or death?

I will ALWAYS use the OEM brake pads for a street driven car.

Compared to the OE brake pads:
How do those aftermarket brake pads perform when cold?
How do those aftermarket brake pads perform when hot?
How do those aftermarket brake pads perform after repeated braking?
How do those aftermarket brake pads perform when wet?
How do those aftermarket brake pads perform from [say] 80 mph to zero?
How do those aftermarket brake pads perform before they are heated up?

Brakes are amazing on the GS, so I'm thinking 3-5% less would still be pretty damn good. Thinking I may try some of these pads myself...just for test purposes.

Has anyone slammed on their brakes lately and think we need a brake upgrade? You probably benefit with wider wheels and tires instead.

There is always an argument for performance. But considering not everyone drives a car like a GS and yet they somehow manage to stop in time without damage, odds are you'll be OK.
