Advice please on best way to upgrade 84S brakes
Advice please on the best way to upgrade an 84S brakes. I have a complete 87 S4 donor car. Can / should I take the complete front suspension (wishbones / axle / hub / disc / calipers) or just pieces thereof.
I would like to achieve steel ball joint upgrade in the process as well.
And should I bother changing rear brakes? Most improvement would come from the front wouldn't it?
Any problems with brake lines / brake pad sensors with this type of upgrade.
Happy for any advice / suggestions.

If you are using it for street useage, do the complete suspension. If it is a track car, you may wish to keep the older upper and lower control arms.
good luck.

If I had the luxury of a donor '87, the whole front suspension would be swapped, as fst951 says. Add brake lines, sway bar, and drop links to the list - ie., the whole front suspension! Wheel/caliper clearance will not be an issue if you have the forged wheels. Also, if the donor has been sitting a long time, check all caliper pistons for free movement.
The rear exchange of calipers/discs is pretty straight forward: Only a spacer is req'd with the orriginal discs - it may not be needed with the S4 disc.

I did the upgrade on my '85, but did not have the LUXURY of having the full suspension. I would DEFINITELY go that route.
Otherwise - you will have to do a changeout of the front spindles to older (~'79) front spindles, upgrade the ball joints and use some no-so-cheap (~$300) adapters for the calipers.
REGARDLESS of which way you go - the stopping power is <AWESOME> Folks with 928 driving experience that have driven my '85 on the track cannot stop talking about the braking. With the cross-drilled rotors and Hawk+ pads, it makes the car feel 1000lbs lighter.

I'm about to do the conversion on my car (front and rear).
Do I really need to update the sway bar and drop links as well? I'm also curious as to what advantage (as fst951 suggests) there might be to sticking with the older upper and lower control arms.
