78 firebird front brakes

Does anyone know if the front brakes on a 78 firebird are the same as the ones on the trans am? Are they the same as the camaro? I'm having a tuff time finding a front brake upgrade kit that fits my car specifically. I see a lot for the camaro but I'm not sure if they are the same. I would think they are, but i want to make sure.

7 bills for brakes do you really need that??
with no better swept area over the stockers,,
I'd hunt around team camaro forum for links to the b body brake swap.. that gets you 12" rotors..
I'm willing to bet there is calp. brackets to install c4/5/6 vette brakes
the fiero guys did it , the monte SS guys, I'm sure the f body guys have also..
the fiero guys use the fiero rotor "hub" machinging off the rotor and then the vette rotors slip on top after changing the lug pattern , it moves the wheels out 1/4" but get 13-14" brakes= more swept area..

this is a SS thread that shows the 2wd blazer spindle with c5 brakes used on 78-88 g.m. g bodys..
http://www.montecarloss.com/communit...863#Post933863

point being there is more ways to skin a cat..
the kit you listed is nice but , the rotors are the same size as the factory f body.. 4 pistons great, same swept area, not ideal.. a little lighter than stock, good, but at 7 bills.. unless your firechicken needs everything(rotors/clappers/lies/etc, you won't get much for that 7 bills,, without a supporting cast..(better springs/shocks/roll bar/ tires/etc..

I looked into the c5 bake upgrade and parts will run me about $650. The b body stuff seems like it will still need some upgrades if i intend to do any track driving, and it will still cost me over $450 just for stock parts.
I get what you're saying about the wilwood kit being factory size though. The car is getting lower 2" in front will new shocks and braided lines. Rear is getting disks and a 4 link with coilovers. With the disks in the rear and 4 pistons on the front will it be up to that task of doing some track driving?
Plus the car will be somewhat lighter than stock.

remember the t/a shock mount was never engineered to hold up the car, if use'n coil overs you'll need to add a crossmember and tie that in to the car well .
they are nice brakes, but I'm cheap and those cars are heavy even when you toss everything you can.. and nose heavy..
I think my 80 almost was 50/50 weight front to rear with NO ENGINE INSTALLED.. bigger front swept area will be better for a track car..
good luck. the are listed as med/duty you'll have more brake than tire.. most likely.. you changing the a-arms?

All I'm doing in the front is brake upgrade, new coil springs, and fresh shocks. The rear I'm using the Heidts 4 link setup. It's bolt in an looks like high quality. I've heard a lot of good reviews on it.
I know these cars are heavy but I'm hoping to drop a few pounds with the ls swap, relocated battery, lightweight seats and other odds and ends to lighten/even out the weight.
I'd love to go tubular suspension in the front but if I'm dropping at least 4 grand on the ls and 4 link i don't know if another 1000 is in the budget. Plus I don't know if the benefit is worth the price. The stock setup handles pretty well as-is.
