TireRack has big brake kits for FR-S.

Check it out!

I saw those a few days ago.. I was on TireRack hoping they would have the BRZ/FRS picture up so that I could look at how different wheel options looked on the car..

From what I've been reading, the BRZ has very good brakes right out of the factory.. perhaps a pad upgrade and maybe some stainless steel lines might be an improvement, but I don't think a BBK will be worth the cost for 99% of BRZ owners.

That's exactly what happen to me lol

That's it.
Pads, lines, fluids = job done, for all but those who are making it a focused HPDE car or bling-mobile.

3,000 ha that's 10% of the car's cost.

Bling bling though.

i think most people wanting to turn it into a track car will be able to find more reasonably priced brakes that will perform just as well if not better. i don't plan on doing anything other than pads, lines, and fluid to the brakes on mine.

BBK's will be pretty lame on this car unless you are putting out seriously more than stock power... I really think it will make the car worse, even when tracking.

That depends entirely on how well developed the kit is. There's no way around it: the track will demand more heat capacity than the stock brakes have. Bigger brakes are the only way to accomplish that. I agree that street cars will see no benefit, but track focused kits (AP Racing) will likely be well-developed.

Big brakes add rotational inertia (less acceleration) and unsprung weight (less grip), so unless you're getting brake fade despite having proper ducting, a BBK is only going to increase your laptimes. More cooling is almost always a better option than more thermal capacity.

I'm excited to get some time with the car and see if I can make something fuctional/good looking using the foglight bezels.

Lighter aluminum calipers with 2pc floating rotors won't add that much rotating or unsprung mass if any at all.

I hate to break it to you, but those 4 piston calipers are going to be heavier than stock, and even if the rotors are the same or less weight, the weight saved is in the center of the disk while weight is added further out past the perimeter of the oem disk. Rotational inertia is proportional to radius^2; Larger diameter rotors mean less acceleration, there's just no way around it.

That makes sense, but makes no difference to me. I don't plan on going past fluid/lines/pads.

I don't see myself getting a BBK for this car, but did you guys notice that the 345mm is more expensive (by $1k) than the 355mm BBK? I wonder why that is. I didn't get a chance to read in detail, but maybe the 345mm kit uses larger calipers? More pistons? Monoblock calipers? Makes me wonder.
