Convert small to large offset
 

I have an '86 NA that uses small offset wheels. I'd like to convert to a later large-offset suspension, partly for wheel availability, partly for greater comparability with M030 suspension and brakes, but mostly for ABS retrofitting.

I have the M456 option now, with Sachs front struts and Koni rears.

I'm not necessarily going to do the full M030 conversion at the same time, unless I can't reuse any of my existing suspension.

What parts do I need to convert my existing suspension to the later large-offset setup?

I think all you need for the rear is the hubs.
For the front, the control arms are definitely different, and maybe struts and spindles.

I think I'm starting to figure out the answer, at least partially, is to look at the parts diagrams for a 944 Turbo on 944online.com Find Parts and tools For Your 944, 944 Turbo, 944 S And 944S2. or the catalog here at Pelican and look for the parts that say "87+" in the suspension, steering, rear axle, etc.

If you already have the rotors, calipers and struts iirc you also need 87+ front hubs, spindles, control arms, flexible brake lines and for the rear you need caliper spacers, hubs and hard brake lines.
