Is it ok to only upgrade your front brakes to a BBK?

[Frogsupra]

I have been tracking my car often and have noticed some brake fatigue during the end of some sessions. Will my braking be balanced the same if I upgrade only my front brakes?

Thank you for any responses

I linked the brakes I was interested in

Those brakes are worse than stock for track use.

What kind of "fatigue" are we talking about? What brake pads and fluid are you currently using?

I was going to say the same thing as @razorlab -

yes, you can do front bbk only and maintain your brake balance, but don’t buy that bbk.

Either get AP or Brembo if you can afford it, or you could try something like stoptech or alcon if you don’t mind gambling… not sure they will really fix your issue though.

you may want to try new pads and/or brake cooling ducts first. And giro discs might evacuate hot air better than oem rotors. Even fenders or fender vents could help.

the bbk will save weight and may improve modulation, but short of AP’s top kit, I’m not sure how much of a cooling benefit you’ll get. Same amount of heat is going to be generated if you’re using the same pads at the same track.

Thank you so much for the replies.

I am using high performance brake fluid, forgot the brand but I believe it had a boiling point close to 600.

Still currently using stock pads, I am also using the smaller brakes that come with the 2.0 Supra.

the fatigue I was describing was a slightly mushier pedal

Will look into those other kits and save a bit longer, fortunately have all winter

Upgrade the pads first. Why not just get some 3.0L takeoff Calipers and rotors? Will be way cheaper than a BBK and probably be more than enough for the 2.0L

As I mentioned in other threads I went down the big brake path trying to manage heat and cracking of front rotors. So if you are referring to soft pedal for “fatigue” then need to look at fluid and pads first. You have to bleed fluid more frequently especially on fronts if you get them hot. All of the kits and pads I have tried all run in the 1000 to 1400 +degree range. So brake cooling duct (I have verus) is something you should consider first. Second I would not recommended drilled rotors. They will crack. Also the big break kit did add a bit more stopping power but not that much as the difference between 14” to 15” rotors is not that significant related to pad surface area. It does give you a bigger heat mass so can help on trying to manage brake temps. But do not think it will be a huge difference in stopping power. The stock set up is really good. Last you need to look at replacement rotor cost and availability of what ever kit you choose as you cannot just buy a rotor off the shelf and you are stuck with getting the one the kit used and I think you will find they are quite expensive. Pads shape/ availability of compounds etc also needs to be researched for the caliper that is in the big brake kit. So would make sure you research all if this and not just jump into any brake kit.

I go through a set of OEM rotors per season. I would upgrade your fluid even higher.

This. Look for some 3.0 take offs and then listen to the guys in this thread regarding fluid and pad recommendations. They’ve been tracking their cars for a long time and know what works.

Same price for front and rear as most Front options.

Thank you all so much, extremely helpful and insightful.

Upgrading just the fronts are fine. We have Brembos and APG BBKS for the supra. As others have said, try a solid fluid, new pads as that can make a big difference from OEM.

A lot of BMW's use the exact same caliper/rotor as the Supra 3.0L so you can find some takeoffs for pretty darn cheap. I can help with part numbers / models if you want.

Didnt realize he was on a 2.0. Yeah do this 100%.

Hey guys already found a local person willing to sell me their 3.0 set. Thanks again

Like everyone else on here, so spot on brotha! I just got a nice backup set of rotors on RockAuto. Mega affordable! Sill on my last RockAuto set. Any relation to @Rocksandblues ?

Castrol SRF has a super high wet temp for fluid, well worth it imo. And soooooooo many pads to choose from. Damn I love this car ?
