Big Brake Kit upgrade over TT brakes

I have a 94 TT Supra, she's in great condition, but coming from my M3 I feel the brakes are not good at all. I don't feel super confident at high speeds if I had to brake hard like I do with my E93M3 and my X6M.

It's an 1100hp stroker build.
Theres lots of spirited driving and highway runs and drifts.
Cage coming soon.


I have been thinking of getting a BBK because of this, and wanted to know
(FROM THE GUYS WHO HAVE BBK) ONLY!
Is there a big brake performance gain if doing a

6pot 356mm bbk upgrade over stock TT supra big brakes?

Or is going bigger rotor and larger caliper just for cooling purposes? And actually stoppage power is the same??


I really don't want to hear from the guys who just have to say keep the TT brakes that's good enough and you dont need big brakes it's just for show etc. Because that's not the pojnt of my post, I just want to know if there is a better braking experience, not if the TT brakes are good enough for a stock supra.

I want to hear from people who actually know the brakes and know big brakes and the differences they make.
Thanks in advance!

Your supra is not your m3 or x6m and vise versa. If you spend money on a nice set of brembo gt or stoptechs you will gain some bite and braking power. As with increasing power in any car you will tend to do things that exceed what the original brakes were designed for.
Post some pics of the car and videos of you drifting also.

Thanks

Ty and yes I'm spoiled from this factory beast brakes. That's why I needed some input. I have a build thread on here called.
(Not your usual purist supra build)

Hey man, I'll be straight to the point...

14", Stoptech Trophy Sport BBK up front, stock 2 pots in rear with a single piece rotor is fine, no need to upgrade to 2 piece.
Make sure the front rotors are 2 piece tho.. No need to upgrade the rears at all, waste of cash but upgrade the rear brake lines to braided.

Put that money saved and upgrade to stickier tyres!!.. Don't skimp out on Tyres man

You can fine tune your brake modulation with different pad compounds depending upon your application from hard street driving to amateur track days.

Brake pad makers are in abundance and fairly cheap with their offerings with this combo.

I personally have this combo on my MKIV. Its my 3rd set of BBK and by far the best. The front Kit is not cheap and nor should it be either. Open the box, hold the caliper and the quality smacks you hard in the face.

Thanks very much for the info: I am doing Airtekk BBK. 356 6 pot front and 4pot rear.
Japanese brand. And was hearing alot about the pad compounds on my thread on the 2jz and supra facebook groups too so will def not get race pads because I want more instant bite.
And yes R888 are the only ones fore. [emoji3590][emoji91]
285 or 295 front and 345 rears.

Be sure to post your feedback on the Airtekk BBK for the Supra. I've been running their Front/Rear kit on my 3000gt for several years. Despite some poor customer service problems with them, I've been happy with their product. I'm running the srt8 Brembo BBK on my Supra. I can tell it bites harder than the stock calipers but I have no real world metrics to supply:)

I will for sure, I actually am still a little torn between Wildwood brakes tbh.
Their 380mm kit front 8pot and rear 360mm 6 pot. Is around the same price as Airtekks kit. And I'm gonna use that as bargaining power, since Wildwood has been in racing for a long time plus I heard the Airtekk might actually be taiwan made for the Japanese company and not fully Japan made lol I thought.

Personally, I would get the Brembo or Stop Tech. I’ve had several sets of both & was extremely happy with them. Brembo are Italian made and the biggest performance brake manufacturer in the world. That’s why they come on all of the high performance vehicles in the world. Stop Tech are US made.

Hi Steve, interesting to read you've had several sets of both. Why are you changing big brake kits and which do you prefer?

Thanks!

I know i shouldnt be replying because I dont have a BBK but thought i would post a link to a thread from a UK site as it has some interesting information

To answer your question on why you go with a larger brake system, it provides more leverage for additional brake torque. Additional benefit is that you have more mass to convert kinetic energy into heat. Eventually you don't have enough mass to take more heat. That's when you discover how good your favorite track's runoff areas are. However, your brake system is only as effective as your grip, so suspension, alignment, and tires are equally important.

If you want to learn more, there are some great resources out there. AZ Performance also sells some thoroughly tested Wilwood setups for our cars, and I'd highly recommend them. Been running one on my car for about 5 years now, and have never been disappointed with the results.

Cool, enjoy your air bags and big brakes. Post videos of the drifting and racing!

Matt
For the reference, all my cars were static on coils for 20 years.

add me on my personal IG:
@gabegabesvegas

I post some videos and more updates than here and also I do promotions for clubs and hotels in vegas for when you guys visit I can hook you guys up!


So happy to have bags in my other cars also finally at 40 years old I made the best decision of my tuner life haha.

My M3 kept having issues with the oil pan when going over speed bumps, after 3 oil pans and some expensive spoilers going to waste I finally decided on the bags

I have a youtube channel for the racing or cruising videos.
Car shows and meet.

My initial response was MKIV-specific, until @raamo reminded me of Wilwood. Have the Wilwood 6/4 package on my MKIII and a Wilwood-based 4/4 package on my MKII. MKIII brakes were from AZ Performance and MKII brakes were from Raptor Racing (not sure if they are still offered).

Anyway, the braking performance of both cars is outstanding. Pedal feel, initial bit and easy modulation are very good. Highly recommended in both cases.

Thanks to everyone that pitched in, I decided to go with the 380mm 6pot/4pot Brembo kit!
Dusty from MVP Motorsports was amazing super knowledgeable and helpful!
I would definitely recommend going through him for Supra parts!
Everyone else said there was no supra specific 380mm kit.

Congrats. That's what I have and have been running them since 2015. You can fit certain 18s like the CCW now Weld Corsair series wheels and the Volk Racing TE-37 (Supra specific). Enjoy the brakes!

If you want to deep dive into the technical aspect of braking Centric/Stoptech has a white paper section with various topics in relation to braking that are very detailed. Be sure when scrolling to the end of the page to click "load more" to see additional pages. You'll find a link to that area on their website below...

BremboNA should have a template to be used for this in case the Corsairs do not float your boat (they are truly bad ass IMO). In case you opt for something different than the CCW Corsairs, a template will take the guesswork out of the equation and make this task much easier for you.

I have the template, I sent it to multiple wheel brands and they all say they cannot make 19 that will fit those brakes lol I hate CCW’s never seen a design that I like

I am at the point that I may shave down the caliper to see if they clear the barrel. Does anyone know how thick the outer wall of the caliper is/how much material I can safely shave off?
