Just want to ask if you guys are happy with the stop brakes on your IS? I noticed that when sudden braking is needed, the i.s. front is so much stronger than the rear making the front dip so much. Unlike my BMW, the feeling is like the whole body (front and rear) flattens the ground on sudden brake rather than the front dipping. I asked around and according to experts, it is because we are using 4 pot in the front and the rear brakes is just to weak. It is not noticable on city driving but once you go hi speed and you suddenly hit on your brakes, then you feel the difference.

felt fine to me when I was on the track. Then again I do have pilot super sports, not the junk stock tires.

OP, is your car lowered?

I have no qualms wight he breaks, I had to break urgently a few weeks ago, and the car surpassed my breaking expectations!

The brakes are a stand out feature in IS350 F-Sport. I am totally satisfied with brakes.

The brakes are great for factory, tires not so much

I am probably the only one here not happy with the brakes.
I have the F-Sport brake and I hate the braking feel.
Swapped them out after 3 months of owning the car.
The F-Sport brake pads do have a strong initial bite and then it feel like its loosen up the grip.
It does not feel linear.
Currently running on EBC Yellow Stuff and couldn't be happier.

I'm very happy with the brakes.. Would like to see less brake dust but it's not too bad

You're doing it wrong. Keep your head up more and read the traffic. Your BMW is not much different. Problem found between steering wheel and seat.

upgrade your tires first if you want better stopping power. Stock tires are junk

Stock for stock, I think the brakes on my c300 was much better. Felt it had better bite and stopping distance

That's all for me too. There's a high pitched squeak sound if you let go of the break at a certain position. Goes away after driving for a few minutes. Cold issues I'm assuming.

Uh dude, the car dipping in the front has NOTHING to do with the strength difference of the brakes. It has everything to do with suspension geometry and stiffness. And really, all cars do this. It's simple physics, didn't you take that in high school?

When you're on the brakes, all the weight of the car gets shifted to the front wheels (this is why front brakes are always larger/better). With all the weight going forward, the car pitches forward.

Conversely, when you accelerate, you get "squat" where the trunk seems to lower and the hood comes up. Again this is largely dependent upon suspension stiffness and geometry.

So yeah, front/rear bias of brakes has absolutely nothing to do with what you're reporting. ****, I know a ton of folks who do track days who will actually just disable the rear brakes entirely because when almost all of the weight has moved to the front, all the rear brakes can do at that point is lock up, which is bad.
