Sc brake upgrade

[speedman]

I have a 70sc and I want to upgrade the brakes. What is the best brakes to fit to the car

Turbo upgrade is nice.

Well, you need to define exactly what a "70sc" is before anyone can prescribe an upgrade for you. If you have one of "those", then you have something truly special, and we don't know what you are starting out with!

[RWebb]

obtuse, but he is saying you don't have an SC - they start in 1978

a 1970 911 would be a T, E, or S and will have a long hood that swoops down

you always want to have 3.5" spacing on the front strut to put on "upgraded" brakes...

what is your VIN?

what problem are you having with the current brake setup?

[Oh Haha]

He has a 79 SC.


What is your intended use of your 911?
If track, I would suggest either a complete setup off of a 930 or even look at some of the upgrade kits offered here on Pelican. I think they are based on the Boxter but don't quote me on it.


If you are going to drive mostly on the street then I would suggest just giving your factory setup a good overhaul and maybe adding slotted/drilled rotors and more aggressive pads along with SS brake lines.

I have the stock calipers with drilled rotors and Ferrodo pads and I have had no problems with my brakes doing the job. Mostly street, in my case.

Bottom line: Just like going faster, braking better can cost whatever you want to spend.

To clarify, I have a 79SC. I love being corrected by the experts! Anyway I have intentions of installing a 3.6 motor and want to do a few DE events. There is a four corner set of 996/993 big reds for $1800, but the black mono blocks would be a little cheaper. What I want to find out is what people are running

[Oh Haha]

I posted your question over in the track/autocross forum. Those guys run a myriad of setups and can give you first hand knowledge of what works and what doesn't.
Help with brake upgrade, please.

Between the 2 forums you should be able to get a good idea on which direction might be best for you. Good luck and , as always, post pics of the upgrades!!!

[speedman]

thanks for your help you are great!

OK, here's the variables you need to factor into your upgrade. After you complete the ~$13K change to a 993 engine, determine what rubber you're going to run. The larger the contact patch, the larger the brakes (and master cylinder) needs to be. You'll find that if you go to Big Reds with a 19mm master cylinder, you'll not be happy with the pedal length. You'll soon be looking for the 23mm MB master cylinder. Now tires: You going to run some DOT "racing" rubber or you going to slicks? If slicks, how large? From practical experience, I've learned this is important. What are you going to do with the suspension? Once you upgrade the power (go-fast) and the brakes (stop), are you going to work on the suspension to stop the front end dive that's going to upset the car's balance when you decide it's time to stop? Don't know how much time you have on a track, but when I was instructing, I ALWAYS told the students to learn with the engine that came with car on the hardest tires available (car control) before they began upgrades. The car will talk to you. If you do all these things without the practical learning experience, you mask what the car is trying to tell you and you set youself up for "issues" down the road. Ultimately, it's your money and your car. Buenos suerte.

This is a complex question with no simple answer. A street car with a 3.6 does not need an upgraded brake system. A race car with a 3.6 may need a better brake system. Some things to think about are what do you intend to use the car for, have you exceeded the braking capacity of your current system, have you maximized the brakes of you current system, how much do you want to spend, do driving style, etc.

I have had a 930 brake system on my car when it had 930 flares, a 3.0 L motor, 18 inch wheels, and the brake were clearly more than what I needed. My car still has the 3.0 L motor, but runs the standard SC body flare and 16x7/8 Fuchs. My brakes are boring, with 964 C2 front and Carrera 3.2 rear calipers clamping down on 3.2 Carrera rotors. The brakes are right for the car and I have no brake fade during 30 minute races. These are two data points. You need to consider others. You need just enough brake for racing. For a street car, I doubt you need anything more than your stock system.

For those, you'd need 17" wheels too.

I used to have 993/S4 in front, 965 in rear + SS lines + 23mm MC. I loved those brakes.
That's what I'm going to have on my 87 Carrera 3.6.
You can run 951 16" Fuchs with this setup.

When I did my 3.6 conversion the brakes were upgraded to Big Reds. Needed 17" wheels and the fit is very tight. If you have/plan on having a thru the body adjustable sway bar, make sure your brake lines are clear,not only with the car on level ground but also under hard braking and hard, tight turns (AX). Ask me how I know....

The braking power with this set up is awesome.

have you tried looking through the innumerable previous threads on this topic?

If not, it's time to do a search

[KTL]

Like Bill said, do a search to know what's been done right and what's been cobbled together to look like it works. Unfortunately you'll find a boatload of information to wade through since the brake upgrade thing is beat to death on a daily basis.....

$1800 for a 996 or 993 setup that works is a good deal. I'd jump on that, if all parts are in new-ish/rebuilt condition and properly adapted to fit your car. Why not post the specifics of what that setup entails and we could give you some feedback on it?

Bottom line is you will need some more brakes if you don't pussyfoot the 3.6 SC car at DE events. If your braking technique needs help, you'll definitely need some more brakes. Hence the reason the guys suggested you consider everything you intend to do with the car and maybe wait for upgrades until you hone your skills a little more. That is, if you are indeed a bit new to track driving. If you've got experience, well then forgive my assumptions you're a PNOOB.
