Anyone gone to Big Reds on a SC?

[pbs911]

I love my Fuchs, but have an incredible opportunity to get some new Brembo Big Reds for my 78SC. Aside from the obvious need to get rid of the Fuchs for 17" wheels, anyone have an idea of any modifications that are needed? Pic appreciated.

On top of the cost of the calipers. You have the added cost of the adapters to fit them to your 3.5" spacing that you have now (I think they run around $300.00 a pair) and then the cost of the rotors ($200-$250 ea.). Also you will probably have to add a 23mm MC to make it work properly.

Doesn't make sense, IMO, unless you've modified that SC in some major way. Why add the weight?

Jack, Cost + 10% for the etire bolt on kit. I am also working on installing a paxton supercharger next summer. I want the brakes to be ready for the motor. Thanks for your replys.

You can only stop as fast as your tires can grip. That is to say, if you can lock up you brakes now, you can't stop any faster. Unless you put flares and a really wide tire on your car or have added a significant amount of weight to your car these brakes will just look cool.

I agree...slotted rotors and Pagid pads make an SC an awsome stopper....

[Jack Olsen]

Paxton supercharger counts as a major modification.

What's the ballpark price on the big reds? Turbo brakes or a C2/C4 setup would allow you to retain your Fuchs.

The calipers and rotors are only part of the expense. You will need custom machining of the caliper, caliper adapters, rotor adaptors, new master cylinder and new rims/tires, don't forget that the rear needs to be updated at the same time.

Unless you have acess to an excellent machinist you are better off buying a kit made for your car.

There are some pics at my website of similarly modified little reds(944/964 calipers)

Well, you may not be able to stop any faster, but that's not the point.

If you install big ass rotors and four-piston calipers on your car, you're getting something: energy transfer.

When you brake, you turn electromotive (motion) energy into heat (by pressing pads against rotors creating friction and therefore heat).

By intalling a bigger system you get better energy transfer, and cooling to boot. So on your 143rd lap, you won't be fading, whereas with stock brakes you're gonna feel fade after three laps.

And the Big Reds will have a better "feel" than the stock calipers; the pistons are sequentially timed for more progressive braking.

Have you compared the price of using the lighter monoblocks to the opportunity you are investigating ? They come in several flavors, tho I haven't looked for any adapter setups.

Braking improvement both thermal and mechanical is directly proportional to rotor size. As a consequence the Boxster monoblock upgrade is only marginally better than the stock SC brakes and no better than Carrera 3.2 brakes.

Monoblocks aren't limited to boxsters. What are there, at least three models ( not even counting colors in the same caliper )

I'm running 996tt monoblocks on 993tt rotors (322x32), on a 3600lb quattro.

Lotsa stoppum, little fade.

True, but the generally available & marketed kits are the Boxster monoblocs using 84-89 Carrera rotors. Not a really big improvement.

At the risk of being obvious, don't use an inferior kit.

The 996t calipers are much like the 993 turbo's but aren't bolted together, hold a bit more pad and weigh less.
