Default Bigger Brakes, worth it or not?

To those who track their F's, do you guys think it's worth upgrading to the bigger 15" Brembo brakes?
Or would you rather spend the money elsewhere? I do have the 2-piece FIGS/RB rotors with Porterfield R4S pads already but this mod bug has bitten me again

Depends on how serious you are about your track times.

I don't think it is worth it for the street, it would essentially be bling unless you track. Looking at your mod list, I personally would get coilovers first.

cool, I have a set of road and track ohlins coilovers coming from Japan

I'd definitely like to take it to the track once in a while.

I have the front Brembo monobloc gran turismo caliper and 380 2 piece rotors and they LOOK fantastic! However, being that you already have 2 piece f/r I personally don't think you will gain much in the performance aspect...specifically, you are not going to benefit in the way of negating fade even with the 380mm front rotors.

It all depends on what the "upgrade" is worth to you. Personally, I love my Brembo GT after complimenting the front with a 4 piston rear caliper and of course 2piece 345/28 rotor.

Another thing to consider is the cost of a track pad for the GT front caliper alone....$468 for FM1000 pad set. lol
I run Hawk HPS pads for street..

In a word. No. Carolina Motorsports Park is one of the toughest tracks in the Southeast on brakes. The F has no problems running in 100+ heat and maintaining excellent braking as long as you turn off the stability controls or drive under the limits of the stability controls.

The question to ask yourself is why Do you want to mod the brakes just for looks or is there a performance reason? Are you experiencing fade or are you not satisfied with the performance or feel of your Brembos?

I have modified my brakes with slotted rotors and Ferodo pads in front, and am extremely happy with the feel and performance.

The stock Brembo Calipers are, IMHO, a very good product. Upgrading for the sake of upgrading just makes no sense to me. But again, that's just MHO.

You have upgraded the pads and rotors. f you want more bling, why not just paint the calipers?

The F has huge brakes, and no review has ever criticized them.

Thanks for the input guys, the brakes is now probably the last thing I'd upgrade, if I decide so. Like I said, I already have the 2 piece FIGS/RB rotors and they are great, no complains. Just wanted to hear from those who track their F's.

I just came back from VIR and my instructor who has a 996 GT3 told me even though I have 14 inch brake rotors our cars are still heavy. I totally changed my braking zones from the last two times I went there. Good thing is my rotors didn't crack, my pads didn't wear as bad and I ran two seconds faster than my last time. If I had 15in rotors similar to the GT3's I would put them on.

There's no point upgrading the brakes on the F. Its good enough maybe when we have tuning available and can push the power to at least 600whp.

You have pics of your setup on the car? Just curious!

My instructors have all said the F has great brakes. CMP is way harder on brakes than VIR. Ask Mike at Carbotech. Also, your rotors are going to crack. There's no way around it. Drilled rotors crack sooner than blanks or slotted, it's simple material science.

No. 360mm x 30mm. It's a weird size. Everything else in the world is 355mm. 360 is just strange.
