79sc brake conversion question

[eintz911's]

Hello,I need advice,opinions,options from anyone who has done,or has info on putting 944 turbo calipers on a 79sc.Thanks in advance. Charles Evans

Charles,

I haven't done it, but I do have to ask why you need more braking? I am always amazed at how well my 79 stops without lockup....

Charles:

Search for, or look up, Bill Verburg's home page. He has all of the info that you need. Also there is a company called VCI that specializes in brake upgrades. They are on the web.

I'm curious as Bob, what are you looking to achieve

[rdane]

I had VCI redue a set of 930 brakes for my SC. You can always use more HP and more brakes on a 911. If you guys have to ask....you aint having enough fun in your 911!

rdane, I am geting ready to do this upgrade and am curious as to how happy you were with VCI? And the upgrade itself. I am trying to decide who to go with, Rennsport systems or VCI. I have the calipers already just need them machined and the front rotors and hats, could you take some pics of them for me?
Also what kind of brake pads did you decide to go with? I am looking at Ferodo. I have them now and am pleased but is there something better, not to say that they are bad just have not had much experiance with pads.

Hi Kenneth,
I bought a set of brakes from a very clean '86 930. Then sent my rear calipers to VCI for the mill work. I had VCI make up a kit of everything I would then need to do the install on my car, hard lines, new Master cylinder, front hats and floating front rotors. Total cost with return shipping and no pads was $1500 including the mill work. I am using Ferodo pads now on my SC brakes and like them so that is what I am putting in these. I do have Pagit Orange pads for the fronts but haven't decided if I'll use them on track days yet or not. I would also like to hear any comments as to why Pagit or another high dollar pad is so much better if any one cares to comment. Be happy to take some pictures but everything is shown pretty clearly on the VCI link you added. Do you have something in particular you would like a pic of? I am having the brakes and a air kit installed in the next week or so, just let me know what you want to see.

regards,
Dane

Carrera brakes are always a nice upgrade from stock SC brakes. Especially if you don't *need* alot more braking. Very easy to do and relatively cheap compared to other options....

For the street, the expensive pads don't make sense or course but for the track, Pagids are a good value. When I had the stock brakes on my car ('86 Carrera) I got 17 DE days on the front and 14 on the rear with Pagid Orange. I used them for thousands of street miles too. They are also easy on rotors. Now I have 993f/930r brakes on my car. The rear Porsche rotors measured new after 3 years. (The front VCI sourced Coleman rotors wore out in the same period. )
In short the Pagids are expensive initially but cheaper in the long run.

rdane, What I am curious about is if I have to modify anything else. Like the rear trailing arms by cutting, filing or do the calipers just bolt straight on...and Did you have to bend your own brake lines ect... And how do you like the floating rotors are they noisy at low speeds like the website says and did you get them cross drilled.
Like I said I already have the 930 calipers that someone gave me so I would like to know everything before I jump into it.

OK,so how about 944 turbo calipers on an SC? I know they are a lighter (less unsprung weight)and more powerful clamping force than standard SC's,and I've got a set.I intend to make them earn there keep! So what goes into this setup? I know one of you guys have done this.

I'm looking at brake options myself for my carrera. I don't know what you need to get the 944 turbo brakes on your SC. If you're planning on doing track events, my only suggestion is that you make sure you can increase your rotor diameter and width before you go throught the trouble of installing the calipers. If you don't, your SC rotors won't be able to disipate the heat. If you're not planning on doing track events, the SC rotor should be fine.

I'll let you know as as soon as I know

I am using my original rear rotors which are drilled.....but I ma not a big fan of drilled rotors. The front VCI rotors are slotted. Doug @ VCI really likes the floating rotors and the car is not a daily driver for me so I went that way. I'll let you know. Nice thing is you can always change them out and still keep the rotors so it is not a done deal if they bug me.

I keep hearing "hand of GOD braking" so I am pretty excited to see what the next track day brings. The SC brakes will typically out brake most until they get too hot so these new shoes should be a hoot! I am doing all the add on to solve the original heat problems. The air kit, Pagit pads and titanium liners I suspect will get the job done just as well on a pair of original SC brakes.

But bigger brakes and more HP can't hurt, right?

Some of the best brake info I have found much of it from Bill's site:

These guys had up the best piece I have read but it is now gone:

Anyone know where to tech article on early 911 brakes went?

Just finished installing Steve Weiner's Rennsport kit, on my '83 SC. Fronts bolt right on. All you need to do to the rear is cut off the ears that formerly held the dust shield and possibly slightly dimple the banana arm a tiny bit, like a dime-size area. I didn't have to, but I hear you occasionally do. And yes, you need to bend the rear steel lines yourself, but it's pretty easy. (Of course you'll need a small tubing bender, and not one of those screendoor-spring things, because the fittings are already on the lines.) Depending on the size of your wheels, you may also need 3mm spacers all around, to keep the inside of Fuchs spokes from hitting the calipers in front.

Is this brake upprade for track use. If not, I fail to see why the stock brakes are inadequate. For the track, I would suggest simply changing pads. Pagid Orange pads are not too hard on Rotors and stop like nobody's business. They are not cheap, but they are cheaper than changing rotors, calipers, master cyl., etc.

[Formerly Steve Wilkinson]

Yeah, I drive the car on the track now and then, but I'm not real serious about it. So why did I do the upgrade? Because it was fun. Because I take pride in my 20-year-old yellowbird bomber. You can hear music perfectly well with two stereo speakers, you don't _need_ that 150 extra hp, a saw from True Value will cut wood just as well as something out of the Garrett Wade catalogue...I could go on...
