Euro 84's have ABS, do so some USA 85's. all with the old suspension,
I believe Porsche changed everything because of the ball joints, both were redesigned. It was important to remember what's going on at the time. It's late 83 and The C4 corvette just came out and with the help of tire technology was able to pull 1G on the Skid pad, This tire tech was soon going to find it's way to the 928 and suspension changes had to be made to cope with the higher loads and improve handling necessary to compete in the market place. The greater steering axis inclination angle and new ball joint arrangements both serve these purposes.
interesting... do they have also the longer hubs with of course longer spindles to make room for the ABS tooth ?? and the wheels another ET ?? Or how did they do it , all on the original spindle length ?

Porsche just added a tone wheel to the hub and and the sensor extends like a finger at a 90 degree angle. It's a common arrangement for cars that had ABS designed in after the fact, The next generations of suspensions across all makes had their ABS sensors more perpendicular to the tone wheel by design,.
In this classics C&D article on the Corvette, they make many references to the 928.
I assume the struts are the same.... sure the shocks, don't know about the spring diameter as i used stiffer "race" springs which have a smaller diameter just as the GT also already had.
Yes, as all comes 10 mm inboard , the steering rods need to be 10 mm shorter. That doesn't do anything on the ratio. Internals stay the same. Now that you mentioned, i don't know if the ratio ever changed over de 928 models ???
Sorry no , as long as i have my 2 running 928's i don't sell parts of my '90 GT parts car .
It was a silly question by me as that rack would be left hand drive and no good for me in the UK, but thanks for the info. I know what I need to do.
A quick question about the rears I hope someone can answer.
The S4 uses 4 piston fixed calipers at the rear, as for the front, but the rears still use axial mounting. Are those the same mounts as for pre S4 cars? So do S4 rear calipers bolt right on to earlier cars?
