Best Brake Upgrade with RUF 17's

[SAY - 642]

I have been reading about the different brake upgrades on the boards.

What would the best bang for the buck brake upgrade for an 87 carrera with RUF 17" Speedlines?

Big Reds? 993 C2 ? Boxster S ? Boxster TRC Kit Feedback appreciated.....

For street driving? The stock Carrera brakes are more than enough.

Hi, lupin..the..3rd:

3.6 tranplant is the primary reason for the upgrade

What's wrong w/ what you have?

Hi, Bill:

I guess for the same reason you did yours on your Carrera 3.0 "964 calipers + 930 rotors"

We have lots of wildlife (deer) up here, I need to stop on a dime!

I'm wondering if there are any clearance issues with the Speedlines? Would the Boxster S Brakes work? Master cylinder is being replaced also.

You have to find better reason than that. The stock brakes will stop the car as well as bigger brakes in front of wildlife.

If you are looking for the looks or maybe more heat capacity, thats a different issue.

ok, that's a good reason. i like 964 calipers in front and 930 calipers in the rear. almost perfect 1.6:1 bias ratio and no p-valve required (remove the factory one).

As others have said, your stock brakes will stop you just as well as a big brake kit. If you are tracking the car and need improved heat dissipation, then that's a different story.

Hello, Will:

Thank-you for your reply. The car will be tracked ocassionaly.

What If I decide to build a 500HP 3.6 turbo, might as well prep the suspension now.

If you want to stop shorter you need stickier tires, not bigger brakes. If you have fade issues, get more cooling air to them.

Hi. Max..I really like your 911S

[Flieger]

Thanks.

I think Boxster calipers are lighter than the Carreras and they are 4 piston so I would say that is the best upgrade as long as there is no pad overhang issue. You do not gain any brake torque but all Porsches have brakes strong enough to lock the tires even once the car has been modified considerably for performance. The main issue is fade when doing long track sessions. First thing to do then is to get more cooling air rather than add more unsprung weight and rotational inertia with bigger rotors.

Having a light car helps, too. For street you can get away with most any stock setup. I just have S+M and a light car and get no fade in the canyons. The DOT-R tires mean I don't need to brake much, just turn, since I don't like to be hard on the throttle and going up to crazy speeds on the street. The canyons are nice and tight so doing the speed limit of 45 is enough. 35mph through a 15mph suggested speed turn is about the fun spot though there is certianly more left in the car.

Keep what you have for a max one time stop, use good street pads tha work well cold. I upgraded mine for track use where I was going through a set of A/M pads in a day or two. I'm a total klutz of a driver.

The big brake kits are designed for long life in multiple max g stops.

Most aftermarket wheels have a ton of brake clearance, that is really only an issue for Fuchs and the 944 Fuchs are even pretty good there.

Boxster S brakes are the same as used on a 996, I believe that they can be fitted though I've never done so. You would want a 930 23.8mm m/c for them.

The typical Boxster brake upgrade on Carrera rotors generates slightly less brake torque than stock 3.2 Carrera

personally I like the 993 brakes for balance and material costs - but I use mine at the track - a fast track where heat management is an issue. For the one off panic stop - a well maintained, stock carrera system - with sticky tires and stop pads is tough to beat.

I did a 996TT brake upgrade on my 89 Carrera two Winters ago because i wanted to track my car this year and i have to admit that i've never had a fading or overheating issue yet ...

Some friends of mine with stock 911's and 964's have had brake troubles requiring pad replacements after one track weekend,although for normal use the stock brakes are more than plenty.
I just like the feeling that my $600.00 Pagid pads will last me a whole season without issues and i don't have to bring my Motive bleeder and two liters of brake fluid with me every second weekend just in case !
Bill will give you the best advice,it all depends on your needs and application !

Cheers !

My limited experience is with a handful of these on street cars and a few race cars. For a mildly modified car (even a 3.6 install) i'd give the VCI front kit a go on your car. I loaned these to a friend and it works great on his '87 Carrera 3.2. He's a fast, aggressive driver at the track and he loves what they did for him vs. the stock Carrera brakes. Firmer pedal all the time and pad wear has gone from substantial to minimal.

>VCI front = 951/968/964 front calipers with '86 951 rotor and a hub spindle spacer.

>Use stock rear Carrera caliper and rotor with the pressure limiting valve removed.

>No need to install larger master cylinder.

>Need to have effective brake cooling for the front. Our cars have used IROC fiberglass front bumpers with cooling hoses from bumper to rotor backing plates. PVC home-made or SmartRacing A-arm clamshell manifolds are ideal for routing hose from bumper to rotor backing plate.

I also have the 993-Wilwood front and 993 or 930 rear caliper with 930 rear rotor setup on other cars and it too works great. Very good for dedicated track cars or race cars. However the investment is quite a bit higher since you need new rear calipers and rotors. I think the VCI front/Carrera rear is a very good balance. That said, either must have front brake cooling of some sort for heavy duty use.

I had the 993F/993R setup on my tracked '87 w/out cooling ducts, just scoops, and I have them on my '79 racecar (except 930 rear, which makes it a bit front-biased)with cooling ducts but not tightly sealed rotor backing plates. In both cars I could get them hot enough to soften the pedal a bit. Point being is 993 size is a big step up in thermal mass, but you still need to get the heat out of the front system. The hardware itself is a big factor, but proper high temp fluid (Ate super blue/gold is right on the limit of this for most average drivers), true race worthy pads (go cheap and you'll usually get what you pay for) and effective cooling scoops or ducts makes a world of difference in keeping the pedal high and hard for as long as you turn laps.

Thank-you for insight Bill, it is really appreciated

Thank-you for the links...Your 3.6 looks awesome.
