You can use spacers on the caliper to line them up (IMG:style_emoticons/default/confused24.gif)



Maybe. I guess I feel that this is sort of "janky". Have you seen this method used for a similar application?

Update on 944 hubs.

They don't work becuase they push the brake rotor out too far. This makes the brake caliper to rotor alignment incorrect.

I knew there was a reason i didn't use the 944 hubs ... (IMG:style_emoticons/default/smile.gif)

Have you tried the 944 rear rotor? Its quite a bit shallower.

No I haven't but I assume this would require me to run a different rear brake caliper?

Why? I believe they're within 1mm in diameter.

Hmm, Thanks for the tip.

I never really payed any attention to them when I pulled the hubs off at the junk yard. I thought the rear rotors on the 944 were vented, and therefore much thicker.


I will give it a try.

Ahhhhh.. That, yes, they are vented. For some reason I though you were using vented with this setup.

Go with the caliper spacers... Good enough for Ferrari good enough for you (IMG:style_emoticons/default/wink.gif)

If caliper spacers are too janky, then pull your trailing arms, weld more material onto the caliper mounts, mill it, drill it, and tap it. Ahhhh, perfection. (IMG:style_emoticons/default/biggrin.gif)

Or maybe some red anodized billet aluminum spacers. (IMG:style_emoticons/default/laugh.gif)

Haha! Well I think swapping hubs would be a tad easier than metal fabrication (IMG:style_emoticons/default/smile.gif)

Spacers it is.

Matt did you measure the amount of offset the 944 hubs create ?? Just curious as to the dimensions and wondering if using 944 hubs and rotors would give similar setup specs to the other methods of modification. I went with thw SC hubcentric hub/ stub combo for the 944 cv mod and using the 911 24mm vented rotor with M rear calipers, got 5mm spacer washers from Eric Shea to get the caliper / rotor offset alingment .

Hey Jack,

I have not measured yet (hopefully get some time in this weekend).

If you are looking to push out your wheels for inner clearance, this would help for sure. I will take some measurements this weekend and post back.

So you are running m rear calipers in the rear? Did you lose the e-brake?

Matt

Yes M rear calipers and converted to alternative e-brake. I modified the arms to use 944/928 e brake shoes with 944 shoe expanders. The welds and mod looks fffuuuugggly , but it will work using the 914 passenger side cable modified with the 944 ends to the shoe expander. I check and check mocking the operation of it , inside the 911 rear rotor / drum it doesn't need to expand very far. Haven't installed the cables and such yet , all bench testing . Used part of a 928 and 911 backing plated grafted together to hold shoes and spreader . Welded a 1/4 thick piece of angle for the anchor plate for the shoes . Plans ( yeah right ) are to use a 964 e-brake lever center mounted over the rear of the tunnel , on the list to do in the future and have read just about every thread / post on e-brake mods that I can find.

some cv dim info
http://blindchickenracing.com/How_to/CVJoi..._joints_101.htm

for clarification - this set up requires four 33 spline 944 cvs which are from years 1986/87. pelican has them for $78.25 each.
http://www.pelicanparts.com/catalog/shopca...l_pg1.htm#item0

cause my next car will be suby engine and suby trans and porcharu's magic flanges, i will only be needing from tsi set up for my set up. 2 911 stub axles and 2 911 hubs - along with complete bus axle assys with 100mm cvs.

Andy,

Many thanks for putting this write up together. I'm in the middle of this same project.

Question - Do the 944 CV's require CV gaskets between the stub/cv and trans/cv?

Another way to accomplish this task is with 944/951 stub axles instead of SC stubs. A 5mm spacer is required on the bearing flange (944's/later 911's used a 5mm wider bearing).

And it appears the 951 stubs do not require a cv gasket (they are flanged to fit over the corners of the cv joint).

See 951 stub below - no cv gasket required.

I had to use a cv gasket between the inner cv and trans output flange.

Yes, they do require a CV gasket. If you don't put them in, it slings grease everywhere... BTDT!

No.

Only on the inner CV.
