Hello I would like to know good brake upgrades that will fit inside a 16x6 and 16x7 Fuchs. Are Alloy S calipers any better than A type? I also heard that the 993 reds off of a S4 are the biggest and best? Do I also have to upgrade mastercylinder and power boosters? Thank You

 

Hi:

The very first thing I would ask you is what car do you have and what do you use the car for?

Street use?

Track use?

Racing?

Your answers will frame what brake upgrades/improvements will do the job and perform to your expectations.

FWIW, the alloy S calipers are NOT as effective as A calipers due to flex. 993 calipers will not work with SC or Carrera rotors and will require a larger (305mm or better) as well as different wheels and some spacers to fit your car.

 

Some interesting reading for you,

Per PCA rules I race my SC with stock brakes, race fluid and Hawk Blue pads. I have never experienced significant brake fade and find the brakes effective (although I eat pads). Even at the end of a race they will lock the tires if I am not careful. They are not sexy but get the job done.

 

As mentioned, you need to articulate what your goals are, as 911 brakes are pretty good as is. If you want to see an installation of 911 Turbo brakes on a 911SC, which will fit under Fuchs, see the 911SC FAQ at tech.rennlist.com, and check the last section.

 

Well thats just wonderfull, I suppose that since you have no issues with your stripped down track car with racing pads that no one else should even consider it, because obviously no one else should ever never need such things and everyone that has upgraded must have some sort of defect causing their issues.

 

AES,

Take a chill pill. The post from the G-stock racer described their experience, nothing more. It may be a useful data point to someone. When it comes to brakes, there are many reasons to upgrade, from very functional reasons that are track-related, to non-functional reasons, like wanting calipers that are red.

Oh, and if you were familiar with PCA stock rules, you'd know that the stock class doesn't allow a "stripped down track car".

 

It's funny. We both read JCP911S' post. Each of us took it way differently. You took it as an affront that anyone should consider swapping calipers and rotors. I think he was simply pointing out two things.

• Some easy upgrades to consider starting with are to change the pad compound, and use a better fluid. (Personally I'd also suggest trying ducting, and Ti pad insulators.)
• One needs to consider applicable club rules if racing or doing time trials

I guess it comes down to what one’s goals are. Solve a braking problem as economically as possible, or stuff some fancy calipers and rotors under the wheel for the ‘bling’ effect. .

 

I originally had fluid fade issues when on the track, after considerable research and help from this board, I've had success in defeating this problem with AJ-USA Cooling, Carrera Front rotors/calipers, hawk blue pads, TI pad insulators and motul 600 fluid. That being said, this works well with street tires. I wouldn't be surprised if my fluid fade issues returned with race tires though.

THe bottom line is that if we knew what your use for the car was, we could better help you to solve your problem. ANd if you are just going for bling, that is OK too, but it would change the recommended upgrade. Everyone here wants to help each other. That's the great thing about Rennlist.

 

My 78 SC has stock brakes with Performance Friction pads and ATE Blue, have not had any problems such as fade at all during regular DE use. Just my experience.

 

My experience with brakes is it really depends on the car and the track. Some tracks (like Sebring) are brutal on brakes some cars - especially the heavier ones can have significant effects. Wider wheels, track vs street tires, performance upgrades can all play a part. As Bill mentioned - some want the performance of brake upgrades for the track, some want the the bling with red calipers. Depends on what your mission is.

My car - a 1987 Carrera Cabriolet (8 & 9 x 16 wheels, at the time, euro premuffler and SW chip)was going through brakes like poop through a goose at sebring. Halfway through a session and my pedal was going to the floor - always a quick way to get an extra crease in the middle of your seat at 120mph. I tried the incremental thing AJ cooling, pagid pads, superblue, then motul 600 fluid and still had issues. Finally did an upgrade to 993 calipers and it's the best thing I have done.

Brakes are expensive - even sourcing 993 calipers - etc I am in mine for around 1700. that includes rear 930 rotors, 930 master cylinder, I have wilwood front rotors (309mm x 32mm) with custom hats and Porterfield pads.

Here's a comparison picture - stock Carrera vs 993


Here's the rear rotors


Here they are behind my 8x16 (951) fuchs - they also fit behind 7x16 (951) fuchs too.

As of this writing I have around 6/7 track days and have very minimal wear.

 

No, I thought the first part of the reference you gave advising that the least brake to do the job was valid and that it is not necessary to spend $$$$ to upgrade the brakes.
