Good point, the 300ZX is a pig and over uses the brakes. the same brakes on the FC would be a lot better. the FC weighs 3000lbs for the vert, so that is either 500~800 LBS lighter than 300ZX depending on model. (or was it the supra that weighed 3800?)

it wasnt that thay loced up it was i was running out of rad to git slow enuf to make the tern

You're comparing apples to oranges. The 300zx weighs an impressive: 3300-3500lbs (z32) Compare that with the FC which tips the scales at: 2625-3071lbs. You suddenly don't have an extra 229-875lbs to stop. Not to mention other things to consider (Place on the torque curve, power at the wheels, speed, etc). Automatically you'd have to start scrubbing speed alot sooner than you would with an FC, and that's just based on weight.

If you want to spend the money, you can get a 6-piston big brake kit for a little over 2g's. That's just for the front set though. That includes slotted/drilled rotors and the calipers. On top of that you have to figure out the rear as installing those will not only increase your weight but also throw off your braking balance.

Honeslty speaking however, the 4-pot brake system on the FC's are already quite impressive for stock-moderate power levels. But have you set your final goal with power? What are you attempting to do?

I think you are thinking 3000GT VR4. Supras are around 3500lbs.

if and when i do do a big brake kit im not going to buy some after market kit i will make it my self in oregnal post i was basickly asking if any one has made a big brake kit and what thay have used and if i can git a diragram of there brakets for the calapers and what not but like iv sed 3 or 4 times not to woried about having a big brake kit right know more looking at the motor the only reson it keeps comming up is becouse you all keep branging it up

i wonder if i can git my cobra/3000gt brake set up off my talon to work on the FC lol

Oh, ok... thanks then... I remember one of the cars from "that" club being around ~3800lbs :D

PS: "That club" incudes the Skyline GTR, GTO VR4, Supra TT, and the 300ZX TT.

These were all Grand Touring "monster" cars that came with bigger engines, and twin turbos.

FWIW, better tires will stop you faster.

I used to lock up the tires on my S4 N/A single piston setup qutie a bit at the track if I was getting jumpy on the brake pedal. With good compound, slightly wider tires, the brakes were able to work much more to slow the car down...

Another thing to keep in mind if you're planning on going ahead with the BBK, is the size ratio of master cylinder to caliper piston bore. You'll want to retain the same ratio as stock to keep the pedal feel and not make it spongey, or drastically increase the effort.
