Have a set of single pot rear Brembos from an R33 with disks (300mm).

Question is are they going to be any real improvement over the OEM rears?

or should I just look at D2 or K sport rears

the rears are twin pot .. and the calipers on the 300s are brembo copys anyways .. TBH for Road car stick with the standard rears just use good pads and discs

the brake bios of the Ksports fronts and stock rears is 80/20 split now ... if you stick ksports on the rear your braking will be all most 55/45 you will need to install a brake compensater / bios adjuster so the back end dont lock up on you on corners and all

Lots if info out there on this, I was going to swap to scooby rear brembos for that reason, decided against it.

Stick with the stock rears, the R33 rears from any variant are no real upgrade.

Where do K-Sport (or D2 for that matter) publish the piston sizes used in their front and rear calipers for the Z32?

 

With that information you can work out F/R brake bias.

Depends what you have up front? Ksport matching front & rear is a very good setup when I ran it.

Very little performance advantage of the R33 GTR rears over stock Howard. I have them on mine as I refurbished a complete set and I prefer the aesthetic continuity front and rear. You could get £150-200 for them from someone with the fronts that wants them to match (I assume your fronts aren't Brembo?), you could then offset that against your ksport or whatever you choose.

Thanks for all the info guys, look like a set of rear Brembos will going on eBay shortly.

 

Joely at the moment I do have Brembos on the front although I'm not sure if they are up to the task of stopping the car atm. The brake system needs bleeding, once I have done that I will see if the Brembo fronts are up to the job, but if I was a betting man I think they will need upgrading to something bigger.

ive upgraded the rear discs size to 297 mm from a gto and used the caliper from the same car.

I had R33 GTR Brembos on the front for many years and found them a good setup for the car (with stock rear brakes) for road use. Are

you planning to use your car on the track?

???

The stock rear discs are 297mm, are you sure the GTO discs are 297mm? Sure a bigger caliper makes a difference, but most of the advantage of a BBK comes from the bigger disc and extra leverage.

yes mate the late ones are 297 mm the ones on my t/t are smaller then the ones ive got in the garage which i brought for my gto before i sold it.

Go figure!

My TT is an '89' G plate. The rear discs are 297mm.

How strange your original ones should have been smaller.

Ah well. :)

I'd love to use the front stock ones as rears, mostly for ascetics really. The ways I've seem this done though it looks gash. Then there's brake balance issues etc etc. Headaches.

Yes hope to use the car on a couple of track days.

 

The disks that came with the rear Brembos are 297mm dia so no added benefit there
