I heard great things about the K-sport brakes. They are TÜV approved, so the quality is there.
The Brembo 17z calipers some people are using look very good as well, but I haven't read any reviews about their performance.

A proper big brake kit and 'won't burn a hole through your wallet' are mutually exclusive.

The kit pictured in your post appears to be one of the SRT8 Brembo conversions, those are popular these days and relatively affordable compared to a proper Brembo GT BBK.

Ultimately, what's your comfortable budget and what's the exact model and spec of the wheels you're running? Budget is one thing, and BBK fitment depends heavily on wheel diameter AND caliper clearance from the wheel face design.

If you want a nice baller kit, i can get you a Stoptech ST60 kit. PM me

 

Hey guys, to clear up some fog: I am mostly after aesthetics. So if the brand is cheap (not rubbish level cheap), then it's alright. I am ultimately after large calipers that don't have to be made for tracking with extremely tough materials and precision etching on them. If brembo replicas exist (that arent plastic stick on toys) then that sort of thing is what I am after right now. A completely street spec brake that happens to be larger (for looks)

You won't like this answer, but you're about to waste a lot of money. Upgrading from NA brakes is a good step, but the stock TT calipers/rotors are excellent at doing their one job. But you want to spend thousands of dollars to look like you have even more powerful brakes than a stock TT? And if that BBK can actually do what it looks like it can do, you're only ever going to use 25% of its ability (on the street)? SMH

 

You own a supra so lets get the idea of "replica" out of your head.

With that being said, there are multiple retro fits of OEM brembo brake set ups from other cars that work on the supra.

-17z from VW, Porsche & Audi SUV's.
-Mustang GT350
-Jeep Grand Cherokee SRT8

These all work in conjunction with Lexus IS-F rotors and there are multiple people that make brackets to install them on our cars and you can get aftermarket SS lines.

Ive been doing some research on the topic myself and the Jeep calipers have become fairly expensive and very hard to get due to back order. 17z and the GT350 calipers are a little more budget friendly.

Use the search function, there are some threads that will help with more info for each set up.

😂I'm forced into replacing my brakes because they are "worn and warped." To what extent? I'm not sure. I don't really feel any issues while driving, and my non-mechanic eyes don't see anything other than some rust, but I will take my mechanic's word. I don't want to spend a good amount of money on replacing small NA brakes since I will eventually upgrade to big brakes in the future anyway. I might as well do it now, rather than paying twice. The thing I was wondering is if I could get away with some sort of larger brakes that (yes serve their function) but also look good without breaking the bank. The general gist seems to be that there aren't any big brakes that aren't made for non-tracking purposes. I see big brakes on a LOT of cars around here, and also on classic JDMs (that are clearly garage decorations that see sunlight once every 3 months). None of these cars are tracked. So I thought that maybe there may be some sort of non-tracking alternatives that are cheaper since they aren't so performance focused. Probably not though. It looks like people just pay the full cost, and then not use them for their intended purpose.

If you'd actually like to improve your braking performance with safe and proven parts combos, try these:

-'95-99 Lexus LS400 (Celsior) Aluminum 4-pot fronts w/matching rotors; these OE LS400/Celsior parts bolt right on and are an excellent improvement in braking and appearance for the money spent. The caliper face is blank so you can put whatever decal or etching you want on it. Better wheel clearance than JZA80 4pots too.

-JZA80 iron 4-pot+2pot rears w/matching rotors; timeless proven performance and appearance but not very wheel-fitment friendly due to large calipers. Many BBK friendly wheels will still need spacers to clear stock JZA80 4pots.

-SRT Brembo adapter kits. I'm not sure if the Dodge SRT8 Brembo 6-pot calipers are available or common down there, but it's a very popular upgrade up here. Usually these will be sold as a bracket kit or brackets+lines and you'll source your own SRT8 Brembos. Most of these kits use Lexus IS-F rotors so you get the exact matching Toyota 60.1mm hub centerbore and 5x114.3 bolt pattern. I'm pretty sure that's the kit you've got pictured in your OP. Depending on the kit you buy and whether you source the SRT8 Brembos from a junkyard for cheap or buy brand new, these run $2000-$3000 USD total front & rear, and get you Brembo BBK appearance and damn near Brembo GT BBK performance.

Proper BBK's that aren't as expensive as Brembo/Stoptech but still are reasonably good value:
-Ceika
-KSport
-AZ Performance+Wilwood

I'll keep these in mind when looking around, thanks!

Seem like most of the members (with high post counts) support OEM TT brakes over BBKs.

Well, this is a part of my research stage. I haven't locked in anything, and just getting some Supra drivers' thoughts and knowledge on the topic.

And if that BBK can actually do what it looks like it can do, you're only ever going to use 25% of its ability (on the street)? SMH

Funny you mention this. I don't know how common BBKs are over there, but I see BBKs all over here. And they are mostly on cars that are clearly used as garage decorations. It's not that uncommon. I will start to ask people why they are running BBKs now and see what they say.

There's no 'economy' or 'street spec' to anything except maybe brake pad selection.

Yea, it sure seems that way. I'm clearly new to this topic, so I am still looking into it. I'm surprised at how common they are here locally, despite their prices.

So if all you want is appearance, just get the bullshit plastic caliper covers so you're at least keeping OE quality factory brakes.

I'll never go that low hahaha I wanted a middle ground where the brakes are large, but idk something like 30-40% cheaper than Brembos/Wilwoods

 

By the sounds of it, it looks I will have to just get my OEM ones replaced, and then change/upgrade the brakes again when I NA-T the car in the unknown future.

 

If it counts for anything, I do experience brake fade when doing multiple 250 km/h runs in Mexico on the TT brakes.

Not a big safety issue as there’s always room to coast but I’m gonna do a BBK in hopes of less fade in these instances.

The fade is from your pads (the material they're made of), technique, and fluid. Larger calipers (and slightly larger pads) won't necessarily get rid of the fade.

• Pads: Look at Carbotech's compound webpage. It's all about heat tollerance.
• Technique: it's better to brake intensely for a shorter amount of time than to brake gently for a long period of time when slowing down from 250km/h / 155mph.
• Fluid: Motul RBF 660 or Castrol SRF can take a lot more heat before boiling than auto-parts-store DOT4 fluid.

 

I will eventually probably get just the oem tt calipers but ctsv calipers look great too haha. I just don't see a reason for my goals to need more then the tts, and they look great imo aswell. You might have wheel clearance issues with some of the brakes listed above.

 

Im going with brembos off 2015-2020 mustang gt350s (6 piston). I like that they are radially mounted so the setup is very similar to off the shelf bbk for our cars. The calipers are pretty cheap as well, you can get the pair for usually less than 500. With the correct hardware for the Autosport engineering brackets you can either use isf or gsf rotors which are 14 & 15in diameters.

 

I want to upgrade my NA brakes into some big brakes, mostly for aesthetics and also because the old ones are on their way out.

Buy what ever is cheapest. If you're not tracking it, it doesn't matter.
Don't expect them to perform better than OEM.

Don't flex or do dumb shit expecting them to save you.

 

In your position I would probably look at LS400 fronts with the NA rears. This is budget friendly and an upgrade at the same time.

Many people in the UK have run the Smaller caliper with the bigger caliper up front, its a perfectly good set up.

 

On the topic of BBK, A LOT of owners migrate to retrofitting XX calipers to A80 spindles. I'm probably going to catch a little heat for this but calipers like the SRT8 ones just look like a red banana dangling behind the wheel. Just a flat looking curve.

When branded BBK's are engineered for XX chassis, there's a lot of R&D that goes into the best possible performance outcome when you bolt in on. Caliper piston sizing is very important for example and overall function to work with master & ABS systems. Even the rear braking bias comes into play. Rotor thickness / pad thickness, rotor sizing / rotor veins, 2pc rotors ... Form and function for me. I'm not saying the other transplanted brands won't work but I just prefer an engineered tested product like Race Technologies and Stop Tech etc. spent some time on.

A good pad and rotor on OEM TT calipers are definitely a solid choice, with a better BP temperature of brake fluid. Proven.

Big Brake Kits - Real Numbers

A topic where a guy does a basic comparison, I am not sure it includes the Dodge calipers etc, but it does illustrate your point above.

 

OEM TT brakes, goodrich stainless lines, new fluid, a new master, stock or quality aftermarket rotors and oem or hawk hps pads are shockingly good. But this doesn't sound like braking performance is the goal here.

 

Pretty sure fake BBK caliper covers are a thing. Maybe check those out. I'd just be worried about them falling off lol. Install them around the block before you roll up to Cars and Coffee.

 

Disgusting.
But all jokes aside, it really sounds like what I need hahaha. I will just wait for the Turbo upgrade on my NA, and save up for the BB kit around that time too to install them all together. This is gonna be a massive money pit (what a surprise) but I will let future me decide on its ultimate fate. For now, I am pulling the "brakes" 😜 on this and just replacing the damaged items with new equivalent or slightly better ones

 

Any recent updates on relisble big brake swap vendor's that still exist

 

@pkop2jz

 

I’d go for the stoptechs if I was going down the BBK road…

 

Any 17z vendors for the adapters?

 

Search for Maas Motorsports here or on ig. Makes a very nice kit for the 17z front calipers

 

I run ISF calipers, GS350 f-sport rotors. Great brakes, they're brembos I need to upgrade the toyota master cylinder.

 

It's not 17z right?

 

I’m currently run my BBK adapters with Jeep Grand Cherokee SRT-8 front/rear brembos, ISF rotors 14”+, hawk pads, braided lines and work like a boss for past 6yrs and built entire kits for under 3k. Zero brake bias running my oem 96 master cylinder. Can DM for information.

 

Hello, not sure why I am unable to DM you directly however, can we please get into a chat DM regarding this? I would appreciate your help.

 

Hello Beautiful People! I saw a video where the guy had to modify (grind) the casing off of a CT-V brembo. Is there a Brembo SRT option that does not require that? Would not want to comprimise the casing in any way.

 

the outer part of caliper doesn’t require trim with proper wheels (18 minimum) with correct barrels. My kit comes with all details offset figures and calculations. The part which attaches to the hub has to be notched but with the Brembo calipers being 1pc aluminum and designed for a 8k pound suv removing some material has not caused any issues for the nearly 10yrs this upgrade has been on the market.

 

I’m new to owning a Supra, but when doing my own research on an affordable bbk kit, it was very dependent on the style and size of wheels you had. Certain 18s like Supra specific volk te37sl, didn’t require the outer casing of the caliper to be shaved, just notched for the bracket adapter, while a majority of other 18s did. Hope this helps.

Jeep Grand Cherokee Big Brake Upgrade - REVIEW

Hi all, I just wanted to post up my experience of going with the Jeep Grand Cherokee SRT8 (2012+) Brembo 6 piston front calipers and 4 piston rears. I believe I actually found out about this route via Facebook. https://www.facebook.com/groups/Brembos.SRT8.Conversions/ After reading through...

www.supraforums.com

 

I sell the adapters and apparently not ALL 2pc rotors are equal to oem specs. I have first hand experience as I have installed RB motoring front 2pc and the rotors sit 3-5mm inward towards car. That doesn’t sound much but when the Brembo calipers only have 5mm of spacing to tie rod ends that doesn’t help
