Change to late offset, or not?

Let me ask this of you all.
If the early NA spindles are weak, are the 86 turbo spindles stronger/bigger?
And if so, can I just switch spindles and nothing else so I don't change my offset?

Sounds like you want the early offset. I have a set of 87 Turbo spindles on eBay. I just bumped my FS thread. If you change your mind and want the late offset link

86 turbo spindles are just as weak as the na's. Get the 87+ turbo/S2 spindles and hubs, either way you will have to fit turbo brakes and late struts with camber plates. It will still be early offset unless you cange your control arms.

Late offset tie rods
Are the late offset tie rods longer by 1.125" to make up the difference?
Also which year cars had the hollow spindles for the speedo cable? I'm not seeing any here.

After looking at the PET, the other possibility is that the 1987 and 1988 NA and S cars had different spindles than the earlier cars (different part numbers and different bearings, both inner and outer). The NA and S cars didn't have the 87+ Turbo calipers, they had a version like the earlier cars. My guess is (if someone can measure these) that the 87 and 88 spindles are beefier than the pre-87 spindles. If this is true, the 87-88 NA and S spindles (same part number) are the best spindles for XSChop's Lexus caliper conversion.

spindle strength
I agree that the late spindles are stronger from factory. I just got an email and the brackets that I machined can have larger spindle mounts spredwidths drilled to match any of the late spindles. So basically, no need for the Expensive M030 option stuff anymore (for me anyways). As a side note, I won't be tracking my car, but I will hot rod the #!$@ out of it. If you have ever cryoed a anything like R&P's, you know they last 4-5 times as long as the stock ones. The cryoed Early spindles are no exception. I would put a set of them up agains any late model stuff in a shear test anytime.

I emailed Racers Edge with our concerns about the spindles. They make parts strictly for racing, and billet hubs for late 944s. Thought I would get some outside opinion.
I can see how the hub is a weak point. It looks, and feels like ****ty aluminum. I still don't buy the spindle being that much weaker than the late. Isn't there only 5mm difference in diameter? The early may be the weaker of the 2, but they're not "weak"...... I'm guessing.....
Anyway, if we have our spindles x-rayed and frozen to make sure they're strong, who's going to make the billet hubs?
Xschop ... what do you think about that? Billet hubs? Hmmmm?
Something about switching only the spindles and struts from a late car just doesn't sound right. I would have to see it. Needing to use camber plates with that setup means the geometry is messed up, and must be compensated .... doesn't sit right with me.
Can you post some pics of your setup Mike?

I asked Ian from 944online.com if he had heard anything about early spindles vs late ones failing and this is what he said
"on the early 85/1 non turbo - of course - and the 924 S the left spindle had a hole through it for the speedo cable to go through -
we do have customers ask for 85/2 - 86 - spindles to replace the early type as it is stronger -
I have never seen one fail on the right side -
not saying it dosen't happen - I've just not been asked for a replacement -
could have been caused by many things-
the difference between the 85/2 - and 87+ spindle is the size of the bearings -
the 87 + type take a bearing thats larger in diameter -
thats the reason the hubs and spindles are different -
so Porsche must have realised that the smaller diameter type should be replaced with something a little beefier
Hope this helps"
Granted he may not deal with Racing Porsches strictly but for street application he would have a good handle on the situation.
