generaly yes/no questions.

I read that the 924 got its front suspension from the super, is that true?

Are 944 suspension/brakes front & rear really a bolt in proposition?

[Shadowbug]

EARLY 924 used many pieces from the Super, mostly front and rear suspension.

944 which is an evolution of the 924, used modified super designs, thus you can almost bolt on 944 suspension parts on a super, but they require a little modification.

what kind of modifications?

By "a little" do you mean cutting torch little, or die grinder little?

Die-grinder kinda stuff.
Most (if not all) of the parts can be bought (e-brake adaptors, hub and bearing parts, bushings...ect)
Some parts (like rear spring plates) do require you to whip out the power grinder and have a grind session with your rear shock towers...for bolt clearance.

Do a search for the basics... there really is a lot of info on this, but there is also a few different ways of going about the swap(s) depending on what year and model of car you source your parts from.

AT the moment im using early N/A 944 brakes (calipers & rotors), spindles, spring plates, torsion bars, 19/21 944 master cylinder.

Works great... but i DO need more rear brake, so some sorting is in order at the moment (may try pads.. or hydro stuff)
