I've been reading up on lots of threads about the rear conversion, CV joints, etc. etc. I'm not 100% clear on everything, but more importantly I'm not exactly sure what I have...
A few years ago I picked up a roller that was in the early stages of a -6 conversion. The owner worked at a Porsche shop here in socal, and had put a 1987 SC front end on the car, and started to do the 5-lug rear conversion. So what I have are a pair of trailing arms with some stuff installed. From what I can tell from the other threads, I have a 74+ hubcentric wheel flange, early 911 stub axles, and on one of the trailing arms, a partially complete 911 handbrake. The other trailing arm has the dust shield portion installed, but no shoes, etc. The stub axle flanges measure 100 mm across in total diameter (edge to edge). Now for the questions: 1. There were several threads about spacers required for the hubcentric wheel flanges, but I couldn't figure out where these spacers are supposed to go. Second, is there a way I can tell if this setup has them or not? 2. I'm hoping to use the 944 CV joints, 914 axle, and 911 coarse splined output flanges. Based on what I have are there any issues? 3. Brakes. I currently have the A calipers on the front and stock 914 rear calipers. When I finish this rear 5-lug conversion I will have to choose between upgrading the rears to the V-calipers or moving my A calipers to the rear, and using Boxster calipers on the front. As far as I can tell, there is little to convince me to go with the V-caliper. A set of Boxster calipers is ~$300 off ebay, and I figure I should be able to make a set of adapters on my milling machine. The V-calipers are nearly $600 and offer no change in pad size on the rear. I realize that fora narrow bodied car, the setup I'm proposing is overkill, but if in the future I decide to flare, I'd have the brakes already done. I have a 165 HP Subaru motor, and I'm sitting at about 1900 lb right now, with some weight still to come off. So the question here is any suggestions/opinions? 4. If I do put the A calipers on the back, are they strictly bolt-on or will I need to modify anything? -Tony Attached image(s) |

[attachmentid=179
184] Top pic shows lft 944 spreader =angle pull , rgt 928 spreader slight straight/angle pull -requires a 90 deg bend in cable. 2nd pid shows 928 rear hub WITH steel shoe liner. 3rd pic shows liner - notice the factory welded on rubing block for the spreader. 5th pic shows where I layed the 928 liner on top of a early 911 shoe plate , marked to cut , did so , welded ( mig ) the 928 section onto the 911 section ( I am a very novice welder and this turned out Gr8 , but DA didn't take pics ) 4th pic shows plate , shoes , spreader , cable mounted studing for the best angle to fab up a holder for the cable tube to mount the cable in, and fab the shoe stop / anchor tab. Look these over , think what you want, maybe try it yourself. 944 spreader seems to be the ticket !! Jaxdream |
