Calipers

pkt1213 · 10-03-2006, 01:02 PM

I know it's been covered before but I couldn't find an exact answer. If i have 944 turbo calipers do I just need the bracket to get them to fit. I was looking last night at autozone and they list 89 turbo calipers, rebuilt loaded pair for like 260. What year 911 do the big reds come on?

No, you will need complete new struts and Turbo spindels...Son't waste your money. The brakes on the na are just fine.

I'm rebuilding mine and I'm sure that will make a hell of a difference.

just curious

There are adapters made but i wouldnt use them. The n/a spindle is pretty scrawny to carry the load of the bigger brakes. The best route is to find the proper offset spindles for your car from a 944 Turbo or 968.

I am not to impressed with the single pistons, lots of people say they are up to the task but i disagree. I had a autocross oritented pad with ATE Superblue brake fluid..properly bled, the whole nine. I was managing to get brake fade on autocross courses with some very heavy breaking. Perhaps it was the pad choice but i find that unlikeley. I switched to the 4-piston Brembo's and have not had problems with fade since.

I doubt that you would have those problems with thos brakes. I'll probably just upgrade with the willwood ones.

FWIW, the cost of the Willwood setup can probably find you the 4-piston Brembo's front and rear, as well as the spindles needed.

This way you have proper braking power front and rear. I dont particular think the Willwood setup is the best option, that is just my .2 cents though.

Really? Hmm. The big reds?

Techno Duck · Techno Duck's Garage

Big reds are not neccesary on a n/a car. That is really overkill i think.

I would just look into the regular four pistons from the '86-88 944 Turbo's.

Unless you are doing some major track usage, the Big Reds (or the Big Blacks) are not worth it. Plus they require a completley different spindle, or buying another adapter to fit them to the turbo spindles. The mounting is different, radial mount as opposed to axial.

Oh ok. But then I do have to change out the spindles and stuff then right?

Also I am looking at building a 3L 8V turbo. Maybe have it ready for next spring. Might want the big reds then.

Big reds or the big blacks will be better suited to a car with more power like a 944 Turbo. I can see putting them on that car, but on a measly 150hp 8v car, its really not worth it.

Either route you take, the spindles need to be changed. You also need 16' wheels at the least. The Wilwood kit however allows you to keep the 15's.

So I have to change the spindles one way or the other so i might do the upgrade to turbo brakes now and then big reds when I am making the big hp

That's great you're doing a 3.0 8 valve Turbo Project. A write up would be great when it's up. Sounds like the best bang for the buck. If your moving toward tracking it and you got the Cash I'd go straight to Big Brake upgrade, http://www.rennbay.com/944-big-brake-kit-p-83.html Turbo or 968 Spindles 16+inch wheels (heard 16" fuchs won't fit the Big Reds) and Add a Brake Bias Valve. (or you'll be outta balance)
Some good general info here. http://www.raceshopper.com/tech.shtml

I think there is something like a 1/16 inch difference in the mating spindle gap. Racer X's page had something on modifying or shimming it. http://members.rennlist.org/951_racerx/ (I think under Strut rebuild)

If your just adding power I'd think you could still get away with something like I run. Zimmerman Cross Drilled, Stainless Steal brake lines, Placid Blue or Orange pads, Racing Blue Fluid, and Stock Rebuilt stock calipers. This is what the 944spec racers use. I can't imagine getting brake fad on an autocross with this type set up. (even with 400 Hp. I've tracked with no fade and better than stock Turbo power.

I think the Big Black Brakes came the 928S4. As a pre Brake to the 993TT. but thoes have the bleeder valve on opposite side. Big Brakes add over 10 lbs per wheel of unsprung weight.
Willwood drop like 6 lbs per wheel but will not be as effective at dissipating heat as upgrading to bigger rotors (like on the bigger brake kits) So Unless your rebuilding the Struts right now or got 3K burning a hole in your pocket.. maybe just get some pads fluid and SS brakes lines for now. Optional brake cooling ducts from Gt Racing are nice for tracks and hard DE's

Techno- do you think it was the pads. I ran mostly stock P-cars in autocrosses and never had fade. Or maybe you just drive faster :+)

Well as soon as i get rid of my 4runner and car payment and get some more money in from my ex wife, she owes me enough to buy a turbo s, it'll start getting built. Hopefuly this winter I'll start working on it. The big part is trying to find the best deal on a crank and block, I think I'll use the 968 block cause it has the piston oil squirters and an 89 8V head. So I am def going to need some brakes to slow that bad boy down. I'll look and see what we can get at work.

Getting money from an ex-wife? Yeah right!

The court sided with me and it's going to start coming out of her paycheck. Now if I could sell the car I bought for her.........

pkt1213 · 10-05-2006, 07:44 AM

What cars did the blacks and reds come on. I was looking last night and a set of rebuilt calipers with pads for a 94 911 turbo is 99.99+exchange. I couldn't remember what the reds came on.
