All of those parts are stll available. Beside of the parts Patrick mentioned, also spindles and rear axle trailing arms must be modified.You need to drill holes for ABS sensors.Just checked these parts yesterday when we put junior's project 951 rear axle to parts for media blasting and powder coating. Should not be difficult to make these holes for ABS sensors, place is already there, factory just left it undrilled.

Sorry to hijack the thread but like Chris White said before, the big reds & big blacks are the same except the cross over tube and bleeders. i just don't understand why LR sell the big reds $250 more then the big blacks?

Patrick is right, red powder coat is expensive

i guess so, removing the black, prep and powder coat will end up $$$

another quick Q, if you put the 993tt breaks on the front, what would you upgrade the back with?

It really is a big project to add in the factory ABS, even with it being a sort of free standing wiring harness.
You need: Main wiring harness along with the ABS relay
Four interconnecting wiring harnesses (between the main harness and the individual wheel sensors)
Sensors
Modification to the right inner fender to mount the ABS pump (if you're using the factory location) which is probably availale through a used parts yard if it isn't on your car already
Late offset rear & front hubs and associated steering knuckles
Brake lines to plumb the master cylinder to the ABS pump to the front wheels
ABS brain

That's a lot of stuff. Some of it (like the brake lines) are pretty reasonable from the factory. The harnesses are fairly dear. New pumps are pricey, and used ones, well, they're used and you're trusting someone . . .

I'm certainly not saying it cannot be done, just trying to put a reality check on "how easy is it?"

Because that’s the way the Porsche prices them!

Porsche has a very odd method for pricing parts, for example the 968 M030 sway bars can go up or down $100 every couple of months…its based on some odd computer driven system that looks at sales volume.

Wow they use different hubs? I thought for sure the cars would share the same hubs (save production cost) just one would have a plastic cover where the sensor was for a non ABS car.

The front hubs have the sensor ring on them. The rear have the different offset for ABS, and you need a different inner flange in order to get the sensor ring (which is machined into the perimeter of the flange).

You can use teh same hubs. My friend have those ABS rings available )new ones. Also no need to buy ABS version of rear trailing arm & fron spindles, place for sensors are already there, you just need to drill it open.

its based on some odd computer driven system that looks at sales volume.
That's true happend also in europe when finns bought all 968 M030 bars. Factory run out of them and produced more of them (quite big amount) after that price dropped quite a lot because nobody bought them. When they actually started to sell again, price went up. Most convenient SAP system what Porsche use

If you have your own machine shop... If you have to pay for the machining, its cheaper to buy used ABS components.

Yes, if only you have used ABS components to by from. In this country (and europe) most of 951's do not have ABS. This ABS toothed gear cannot be bought new from Porsche, you need to buy a complete hub; so new toothed gear is certainly much more cheaper to buy. So what is the fact in States is not fact in Europe.
We have also played with the idea of installing a newer ABS technology to these old cars, so might be necessary to fabricate new toothed gear for this kind of setup, because 951 gears might not have the right number of teeth....

Gustaf, that's the good one

Also, how are the LHD and RHD versions different? There are 2 different harnesses but perhaps that's because the module is in a different position between LHD and RHD.
I am looking at retro fitting the ABS from my old '89. As all the running gear is on this car ('86) I hope it's not going to be too much trouble.
