I'm very likely going to be buying a GR86 on launch, but the only thing making it very likely and not definitive is the stock brakes. I track about 5 times or so a year and like to canyon drive, so I would like a nice set of brakes. Unfortunately just some pads wont cut it with the stock 2 piston front and 1 piston rear setup.

Reading around the forum, it sounds like AP Racing or CSG's Brembo GT kits are great options for someone looking for an upgrade in the current toyota 86 platform. But, those kits run $2000 and don't upgrade the rear calipers. The current performance pack for the BRZ runs $1200, and include wheels and dampers (which to be fair I would be replacing anyways, but still).

I haven't been able to find a post discussing brake bias alterations when only adding a BBK in the front, leaving the rear calipers stock. Perhaps I still have a lot to learn, but would that not alter the brake bias?

So I guess my questions come down to brake bias confusion and value considerations.

Thanks everyone

You could just do the brake pad and brake lines and you will be able to brake hard all day. If you want to increase breaking power further, like if you are wanting ultimate time attack then yeah the cheapest way into it is to wait for the performance pack, or find someone will to sell you them second hand from the first edition.

Remember you might be able to sell your own brakes to buy the new ones and potentially make it a bit easier on the wallet.

Hello,

I track about 10 times a year and have been doing so for awhile. This car is pretty light I doubt you'll need to upgrade to a BBK. I agree with comments above, unless you're doing time attack or something very serious/competitive..

Some SS brake lines with good brake fluid (motul, etc) and some aggressive pads like carbotech or somethings similar should be more than enough to get that quick bite and more firm pedal pressure.

Just these basic mods will be enough to do a 30 minute hot lap around most tracks with a car this light. If the car was 3500 lbs, i might have a different opinion.

I have seen plenty of very fast Gen 1 BRZs on track with the stock calipers. Canyon carving certainly does not require the performance pack calipers. On track, as the previous poster said, Carbotechs and Motul and you can run very fast laps for and hours (witnessed at a recent Chin Happy Hour at Eagles Canyon).

Actually, a buddy of mine went from an older Gen 1 to a newer Gen 1 with performance pack. He felt very little difference.

These cars are so light. There is PLENTY of braking ability in the stock setup. Anything more is just for show. Just a pad change will work wonders. If that isnt enough some good vented rotors will seal the deal. Those giant brembos can stop great, I have no doubt. However on a 2800lb car you will easily trigger the ABS with heavy braking on a stock car, or even lock up the tires if you unhook the ABS. How much more braking can there be? The goal is to just get a setup than can dissipate the heat.

I dunno. The stock brakes are never enough for track duty, especially when considering wider, stickier tires which owners are likely to use.

Then get them..!! Nothing wrong with modding for looks. The brembos are better than stock for sure. I just think they are overkill.

You can search up online that BBK really doesn't give significant stoping power than some track pads + rotors + dot4 fluid on low power cars. It really depends on your tires, if it allows you to stop faster.

BBK makes a different on consistency on heat dispersion and converting kinetic energy into thermo energy (which means when you go up in power, you will need it).You might need it when you're doing absolute time attack. Where you're balls to the wall on hard braking at every braking zone, and that track config has a lot of corners. So that your brakes can cool off faster, or obsorb more heat. Other than that, stock calibers are good enough on track.

People who go with BBK in their low power cars are usually for show and stance(if they are stance boiz, they are parking anyways. Not sure the use of BBK).

I originally had a BBK on order but after tracking this with DOT4 and HP+ pads I cancelled them, these seem to brake faster than my neck can keep my helmet up. They might not do for a serious driver that can slam on the brakes deep into corners but they’ve been great for me so far.

I was doing some digging and came across Gazoo Racing parts for the GR86 in Japan. They have a front and rear BBK, 4-pot front, 2-pot rear for ~$4700. It requires 19" wheels and tires that they also sell for $5700.

They should fit under 18s (depending on spoke clearance to the calipers) as they are the same as GR Yaris and they have 15mm larger discs up front. Some folk have managed to fit 17s on the GRY but it is very tight
