Yet another 5-lug rear conversion, some questions Options

[TonyAKAVW]

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?

If there was no spacer the flange and the stub axle being bolted together would flop around, what I see from your pics is the backing plate being installed upside down from waht others have executed for a 911 e-brake setup , you didn't show pics of the top side of the arm. You seem to have all the parts required to convert to 5 lug with the hubcentric flange I feel is a plus ( opinions vary ) just might look into the e-brake setup and how you will get it operational. Hopfully someone may have an idea as to getting that done as I'm sure you have pondered this also. It would be a shame to dismantle it to turn the backing plate 180 deg to get the pull bowtie setup to the bottom of the trailingarm , also look to get a block setup that goes between the shoes that sits above the actuating hrdwre , this is a must for safety reasons as it stops the shoes from rotating around if used for an emergency brake in whcih case with no stop , the whole shebang spins with the disc / drum. There are sevaral threads on here for this setup , use search for 911 parking brake conversion.Good luck and like I said search is your friend.

p.s YES if it is taken apart the bearing is usually destroyed hence my mention about it being a shame to take it apart to rotate the backing plate.
