5 -lug conversion questions Options

[jmargush]

I have a line on a 69 912 front and rear suspension.

Would this be a viable donor to set a 914 up for 5-lug?

Are any of the rear parts applicable, i.e. hubs/axels, calipers?

Would Cookie cutter rims fit this set up on a narrow body car?

Yes. Pretty much what I did on my narrow body six. Rotors are solid instead of vented but work fine and are a little bit lighter. You can have an ebrake if you use the tangerine kit.
Eric’s thread explains most everything. (IMG:style_emoticons/default/beerchug.gif)

Awesome , Thanks

So more questions after reading Eric's post.

Are there any advantages to using the rear calipers form the '69 912? I assume I would loose the stock E brake function without some work around.

On the front struts will the '69 struts accept the existing koni cartridge that I currently have in my 914 struts?

Th rear 912 brakes would be a slightly better match than the stock 914 brakes but you would need to install the 912 e-brake and use the Tangerine Racing adaptor kit. I would just stick with the stock 914 rear caliper, rebuild it, use good pads and new soft lines.

On the front struts will the '69 struts accept the existing koni cartridge that I currently have in my 914 struts?
I don't believe so. I think you have to use koni's built to fit boge struts.

Switching to 5 lug is never cheap. The core parts are only part of the solution. Count on everything needing a rebuild, new pads, rotors, soft lines, bearings, ball joints, etc.

Hi, I'm also trying to gather parts for a 5stud conversion and wanted to ask for some help ID'ing 911 strut types from their part numbers. I'm trying to find 911 boge struts with the later ball jt connection (wedge pin not pinch bolt) and 3" caliper spacing.

I've seen some numbered 901-341-079-01 and 901-341-080-02 and from the pet images I've found they seem 3" (M caliper compatible) but I can't work out what type of ball jt they take. Does anyone know or know where I should look to find out??

If the bottom of the strut has a split, it’s an early ball joint/pinch bolt. No split, it’s later and takes a wedge pin. I think it’s around model year 1972 for 911’s but don’t quote me on that. Bilstein might have always been a wedge pin but again, just a guess, not a fact.
3 1/2 are all wedge pin.

To borrow Mark's "don’t quote me on that" I think all the 3" struts are pinch bolt.
I have the 3" with the pinch bolt, they work okay, make sure the hole is round and just check the torque and condition often.

There's a member that made new CNC wedge bolt ends for his 3" struts, that you cut off the old and weld on the new end. You could do the same thing by cutting off the wedge end from a donor set of /4 struts.
I now have three 914's all with 3" struts, this is how I plan to repair them when the time comes.

No, they made 3" wedge bolt struts. Again, not sure of the year but I've sold many sets through the years and have them on a couple of my cars and a set or two in storage. You can usually find a set with a WTB on Pelican or ESR. Plan on $400-500.
I really don't think pinch bolt struts are all that bad. They were on thousands of 914's, 911's & 912's. You just have to make sure the bolt stays tight.

Thanks Mark E and Mark H - will try and do some hunting to see if there are any threads on someone swapping the wedge end from a std 4 strut onto a 911 strut. Was really wondering about how they aligned it all? [/quote]

Clay mentioned getting it done on a thread from about two months ago. He did it to keep his 914-6 struts (mostly) original. There's no reason to do it on regular 911 struts. Just get the 3" ones that came with wedge pinned ends. They aren't rare and 911 guys sell them off all the time to go to 3 1/2" struts so they can use bigger brake calipers.

Not the best pair but you can get an idea of what you are looking for

I didn't do the work. I had Zims Autotechnik do it. They took a the strut from a /4 with a wedge ball joint and cut the end off of it. Then they removed the end from the /6 strut and put in the one from the /4 strut.

Now they offer this as a service, and they make the wedge ball joint end from scratch instead of salvaging one from a /4 strut.


Call Aaron ( @partsguy22 ) ... Aaron@allzim.com or phone 1-800-356-2964. He will get you fixed up.

Ovaling is a problem but not crazy prevalent. As mentioned herein, if you have this issue, we simply cut the bases off a pair of late model 914 struts and weld them on. We did this recently for Jamie Rusts rare 3.5" Koni struts. He sold them for $1599.00



Also... rear 914-6 calipers keep the same bias ratio with the 911/912 fronts. Aint cheap but, after you weld on bits and try to incorporate a 911 handbrake with varying results of success in the adjustment arena... I'll pretty much guarantee you'll want these:

Eric - I didn’t realize you were making 914-6 rears. That’s awesome! (IMG:style_emoticons/default/smilie_pokal.gif)

[bossboy302]

So you take a 914/4 caliper and bore it out?
Nice!

Nope. You make a new casting.

When did this happen? That is amazing if these are new castings and reproduction of the hard to find and nearly always in need of a rebuild original /6 calipers. And the option for vented rotors. (IMG:style_emoticons/default/pray.gif)

Common question. Bottom line: can’t be done. (IMG:style_emoticons/default/wink.gif)
