How can I put 911S brakes on my 67 911 normal?

[Shawn]

Sorry, I searched and cannot find the discussion that covered the conversion for swb non S 67/68 cars to S spec brakes. This can be done with early swb S brake calipers and rotors. But, the wider/longer S brake caliper bolt pattern requires upgrading the front and rear suspension components to include???

TT has done this. Bud, are you out there. (and Tom, are you racing in Phoenix this summer? I need pit crew experience.)

Thanks in advance. Shawn.

edit: for grammer and spelling this tyme.

also interested in the info. thanks for posting shawn .

I had heard the same, but I thought that S Calipers were only needed (or used) in the front. That the calipers and rotors in the rear are the same in the S as in the Normal (E and T). Is that so?

Also, is there a way of upgrading the brakes' performance without going to the expense of putting on S calipers and the suspension changes it requires? Like using drilled rotors, etc?

Your car already has the hot set up. If you wish to be certain...look for vented brake rotors and inspect for front and rear sway bars. You will find them in place.

My 70T, with many S options . Has 911S spec brakes, and sway bars, and guages, and...all those other neat goodies mentioned in the Max Moritz Autohaus purchase agreement that came with car. (obvious advertisement)

However, my 67 normal is without.

The early (67-68) short wheel base 911 normal cars have solid disc rotors and smaller brake calipers that are specific in size. With this post, I am after early swb 911 car owners that may have performed a 911S brake system upgrade, that may also post helpful information...including a list of the needed parts, installation tips, and/or any additional information regarding this upgrade. I want to do this for both the front and rear brakes of the car. Thanks in advance.

I don't have a SWB car so I apologize ahead of time if any of this is incorrect.

To run the S-calipers you are going to need struts that have 3.5" spacing. I don't think you will have this on a SWB car. If you already have 3.5" struts, then you are set. Just bolt the calipers on and go. If you don't, you may want to look swapping the entire front suspension from a later car in.

Shuie. Go to the head of the line. Thanks for providing the numbers. Good show, my man.

edit: Hey, Wait! I just read that Shuie has a hooligan car! Dood, you rock. We early car hooligans have to keep the faith.

Shawn-

I only just now saw this thread. You are getting lots of advice about upgrading to the later S alloy brakes (or SC or Carrera), but from reading the sentence you wrote above, that doesn't seem to me to be what you are asking about. If, as I read it, you want to upgrade '67 Normal brakes to '67S brakes, there is no need for strut/suspension work at all. The only difference between the two was the vented rotor and a spacer which widened the caliper so that it fit around the thicker, vented rotor. Both calipers had the early 3" bolt spacing, which fits the early struts.

You can easily buy these parts new or rebuilt and bolt them on in a couple hours. Braking ability would not be improved with this upgrade except for superior heat dissipation from the vented rotors, as pad sizes and rotor diameters were the same. Unless you are running the car hard and experiencing brake fade, it will not be any better than your normal brakes. It's the tires that stop the car, anyhow, so it would be better to fit some 205s on it if you're running those skinny original tires.

HTH,
TT
ps- I am not going anywhere near Phoenix in the summertime. You need to come out here to the coast. July 24-25th at the Q -- be there!

OK, TT let's pretend that I am just anothor dork from the north, (the very north) what and where is the Q. ?

I'll get there...tell me how. I really am a fart smellow.

Shawn.

Edit: to change the smiles.

Qualcomm Stadium. Go west on I-8 and get off in Mission Valley at Texas St./Stadium Way exit. See this page for more info.

thanks tom! i guess i think the brakes should be more confident inspiring for normal street use. maybe i'm just trippin'. the brake shields have been removed from the front but are still on in the rear. i will remove them this weekend and post pics of what looks to be normal cast iron calipers. maybe you can confirm? i have no special ducting to cool the brakes and i'm not using ate fluid.
i will ck into your recommendations but it sounds like i should not perform any major surgery. i appreciate the feedback tom.
