I have an S5 NA and want to change out the stock brakes with some slotted brakes. So, i checked on rxecret7.com and looked underboth the pads and rotors. They only sell pads for the fd's and the TII. My question is are the TII stock brakes and the NA stock brakes the same? Thanks guys.

S5 N/a's have single pot calipers I beleive. Unlike the S4's which had the sport and gxl with four pots. That may be the difference. If I were in your situation i'd just get some better brake pads and SS lines.

91_fc

thanks for the quick reply. so are you saying that the powerslot rotors (here ) wont fit on my S5 NA?

that right there says to me its for all FC's but I wouldn't trust it. call and ask them.

91_fc

yeah i did. the guy didnt know ****. pretty sad. if you work at a place like that, you should know your ****. anyways im sure well figure it out. thanks for your help so far man. i appreciate it.

91_fc

yeah thats what i thought. but when i looked at the brake pads it specified for the turbo models only. thats what kind of confused me.

They are the same. As long as your calipers are 4 piston, they'll work

I have a N/A with all Turbo brakes.
The turbo brakes swap right over, but be sure to have the caliper bracket to the front. In order to run the vented rotors in the back you will need the turbo caliper for sure. I haven't done it yet but swapping the turbo master cylinder isn't a bad idea either.

if you get rotors for a s5 n/a and you get a 87 tII rear end will those rotors fit on it or do you need to buy new rotors

andrew lohaus

if you have 4-pot up front and vented rotors in the back, thats as good as its gona get. if you dont have these, feel free to swap up, its well worth it.

andrew lohaus

all rear rotors are the same diameter AND use almost identical calipers (i belive the one is slightly wider to accomidate the vented rotor), if the n/a rotors are vented, it'll work, otherwise it *might* if they are solid.

91_fc

okay. uhh im not that familiar w/ brakes so ... will it work or not?

91mazdarx7

so the rotors are the same for the n/a and tII just the caliper and how many pistons is different

91_fc

thanks!

andrew lohaus

your question cant be answered until you tell us what type of brakes you have!! some n/as came with "n/a" brakes and some came with "TII" brakes. ias stated before, if you have 4 pot brakes up front, and vented disdc in the rear, you essentialy have turbo brakes and the rotors will fit fine. otherwise you will need the n/a only smaller/nonvented disks.

91mazdarx7, no the rotors are not the same, unless the n/a is equiped with the "tII" or upgraded brake package. the rear DIAMETER is the same on all fc's, however, the upgraded brakes have THICKER rotors (beacuse they are vented (as in have channels cast through the thickness of the disk--not to be confused with crossdirlled)) and IIRC they cant be interchanged without doing a 5-lug conversion and/or a caliper swap.

91_fc

okay ill check then. but i just called the guys at rxecret7 and they said that the powerslot brakes would fit. when i get home ill check.

andrew lohaus

stop listening to these bozos. just go look at the dang car and figure out for yourself!

91mazdarx7

my rear brakes are solid so i got the n/a brake package so your telling me that when i put on the turbo rear end they wont fit or what im alittle confused

selanne8

i've done the front brake swap on my 91 n/a. the front rotors are the same, whether you've got 4 pot or single pot brakes.

the rear rotors are different though. the vented ones will not swap in for the solid ones.

j.ho

91mazdarx7

so the front rotors im safe with just the rear rotors i need to change to vented rotors

a4sport

if u guys are looking for a good deal on brakes pm me and my buddy can hook you guys up! especially socal peeps...

91mazdarx7

what can you all get a4sport

andrew lohaus

no front rotors are different diameter, thikness and use different pads with different calipers.

"need" is a relative term. you "need" more hardware than just the rotors to do a proper brake upgrade. its not to difficult, but there is more to it than you seem to belive. look in the archives for rightups on turbo brake and 5-lug conversions, theyll have more details to do it right.

91mazdarx7

if i put in a tII rear end and that is vented and has 4 piston calipers i need to get vented rear rotors for it i cant use the drilled rotors i just bought so am i right on the rear part
now for the front i cant have 4 piston calipers on the rear and 1 pistons on the front so i need to get the tII front calipers and what about the rotors do i need to get different ones now

Icemark

There are no 4 piston rear brakes, only vented and solid rear brake rotors with a single piston.

The Turbo (as well as GXL, Sport, Convertible, 88 GTU, and 89-90 GTUs models (but not 89-90 GTU) and the 91 coupes with A packages (read the option sticky at the top of the page to figure out if you have an A package) came with 4 piston, vented rotor front brakes, and vented rotor single piston rear brakes.

Everything else came with single piston vented front brakes, and single piston solid rear brakes.
