Hey guys, so I have a question for you brake guru's. My brother has a 99' Mustang GT that hes selling right now. Hes pulling of his front Brembo BBK from the car and will give it to me for practically free. Now I know that it will not directley work with my 07 Base model Z... but from what I understand the calipers are universal on Brembo's GT Kits. Therefor Im thinking that I can take the calipers from his set-up and order my own rotors and mounting plates, correct? This would save me a TON of money. Does anyone know if this is poosible and what exactley I would need to make this work.

Again, he has the Brembo GT Kit for a 99' Mustang GT. Its a 4 piston caliper set-up.

Also, If these Brembo calipers can be used from my brothers kit, I would like to purchase the same rotors that are on the Alliance BBK. Does anyone know if I can purchase these rotors seperatley and will they work with Brembo calipers or just the Alliance Calipers?




Thanks guys !

 

is it for sure a brembo gt, or is it the '00 cobra r brakes? way different calipers between the two, and the r brakes are 1/3 the price so far more common.

you would have to check with brembo on the piston sizes to see if the calipers are even going to remotely work on the z. even if they are r brakes i would still test fit them as they may still bolt up.

 

Good question ^. It think its the Brembo GT kit not the Cobra kit but how would we know the difference?

Anyone else...

 

Those are not Brembo GT calipers or 2 piece discs. Brembo doesn't make discs like that, (you can tell by both the curved slots and the fasteners that connect the mounting bell to the friction ring), and the calipers are unlike any in the Brembo GT lineup.

Re-read my post homie, I think you missed something.

The brakes in the picture is an Alliance BBK, and we know that... In fact the Caliper reads that clearly. That is not the question at hand.
Thanks tho

 

Ryan stop being a newb. P.S. the keys go in the ignition, not on the rotor.

 

^ haha... that is not my picture dood. I will be sure to tell the owner tho

Now, can anyone who is able to read thru my post answer my question?

 

since you like the alliance rotors, sell the brembo kit that your brother is giving to someone with a mustang, add a couple bucks, and get a full 4 wheel alliance kit. i hear they're having a crazy sale right now...

 

Hes willing to practically give it to me to use on my car... I cant slang my brothers parts for money though haha. If thats the case then hell just sell it himself and get some money back for what he paid.

I am thinking about Alliance though if this falls through...

Im going to take pictures of his Brembo set-up so those of you who know what there talking about can evaluate wether or not it is in fact the Brembo GT kit or the Cobra R Mustang only kit.

Thanks again guys

 

You'd have an easier shot at getting the mustang kit to fit than you would getting it to work with the Alliance rotors. not all rotors are created identically, some companies change the center position of the rotors to work with their caliper designs, so i wouldnt really go down that route unless you had some alliance rotors on hand to try it with.

You only have three factors to worry about from what I can think of.
1. Rotors for the mustang will require a hub-centric ring as the mustang has a much larger bore than our cars, otherwise the rotor will move on you due to the play in the stud holes (Mustang kits on 300ZX was common back in the day and required this add-on).
2.You will probably have to make a bracket (in the event the mounting holes are cast/forged into the caliper) or source a brembo-to-nissan bracket (in the event its a two-piece caliper/bracket setup like typical Brembo GT kits) to make the caliper mount properly.
3.You'll have to do the research to see how comparable the caliper piston sizes are to the 350Z specific Brembo-GT kit which should probably be your first thing.

I'd take it and then sell it and maybe give him half is he gets bent out of shape about it.

 

the '00 r brembos have a cast in bracket---like the oem Z33 brembos. they also use a 1pc 13" rotor that is the same rotor found on regular cobra's with the 2-piston pbr calipers.

the gt kit would most likely use a 2pc rotor and a caliper with a bolt-on bracket. they would also most likely have an external crossover tube on the caliper vs the internal crossover on the cobra r brembos.

 

UPDATE: So I found out today that they are in fact the Brembo GT kit. I dont have to use the alliance rotors as I understand not all rotors will fit these brembo calipers.. I just really liked the design of them.

So does anyone know which rotors will work with the Brembo GT Kit and where can i get the mounting brackets for them to fit my car?

 

For the brackets, I would search for a brembo brake supplier and speak with them on the phone or via email, tirerack MIGHT be able to help, but Im thinking something more on the grassroots level of service.

For the rotors, I would do the same as above and just get the brembo gt rotors made for the Z or talk to someone at stoptech as they might have something as well, racingbrake.com is another suggestion to consider.

Also dont forget the calipers should be stamped with a serial number or part number, use that to find out the specs for the piston sizes and cross-reference that with the 350Z brembo-gt kit to see if its similar at all. If they're too big or too small it wont be worth it to begin with.

 

helpful.. thanks

I spoke to ppl at Brembo USA(I had no idea they had a headquarters in SoCal) and it looks like its not worth the headache. These calipers COULD fit if I purchased $300-450 brackets, new rotors and pads. The problem is that I would have to find someone to sell me these parts individually(seperate from the actual GT kit) and they typically don't do that. I asked about matching up different rotors other than the ones used on the brembo gt kit(Endlass, rotora etc). Obviously she promoted her own brand, and advised me not to run different rotors, although im sure i could. She said she would get me the individual parts needed but it was going to cost me and the price is just really not worth it. It would add up to the same price as the kit brand new apparently. All in all, Id rather not run calipers that might not have the correct piston size for my car, especially because this will be no garage queen. Regardless of the calipers looking the same size externally, there are 7 or 8 different types of four piston calipers that all vary internally.

... blah blah blah. Point is, it could be done but its just not going to save me money by running these calipers. I want piece of mind out on the track..

Thanks for your help everyone.
