Hey Kaka, here is what I got/need for suspension/brakes.
Front '86 (83-86 are basically the same)944 brakes, everything from spindles out, $69 ebay
complete rear suspension '87('87-89 are the same, 85.5-86 won't widen the track as much, and 83-85 control arms are identical to the vw units with a little more internal renforcement) 944 N/A, thats everything including brakes and axles, $140 ebay
Topline Maxx three bolt struts w/ 7/8" swaybar, $600 from
www.toplineparts.com
Need:
machine work to 944 hubs and 1302 spindles approx $300 by Laner at VDubCustoms.
New pads/rotors/ and caliper rebuild kits, $388
www.pelicanparts.com
if I really want to go crazy for an extra 600-700 I can go with the 4 pot Brembo 944 Turbo calipers.
What I wish I had done differently, is I wish I had bought the 2 bolt struts from Topline and then the 944 spindles are basically a bolt on deal, but the the early Supa's have beefier cast control arms as opposed to the later 2 bolt 1303 struts with their flimsy stamped control arms. I'll be happy with my three bolt setup none the less. There are several tech articles about these conversions and a whole lot of informative threads if you do a search. You will have to run Porsche wheels after this.
