billet hubs?

I believe my hub is bent on my 87' na and I'm looking into getting a new one. I plan on eventually putting a LS engine in my car. Nothing bonkers, no more than 400hp. Are the billet aluminum hubs a must have or is that being over the top? I know paragon sells them for a fortune but I'm sure I could find a used set for cheaper.

What other suspension modifications should be done to my car to track a 400hp 944? Obviously coilovers and such. I'm wondering if the spindles will hold up or the control arms? Do I need solid bushings or will poly bushings work?

I'm no expert on it, but if you're building a street car you don't need to mess with the suspension basically at all, unless you want to.

I want the car to be street legal so I could drive it to the track. Although it might take me a year or two, this car will be a track car.

It is the 86T hub that is the weakest and they do fail. The early spindles with the cable speedo are the ones that fail easily as well. I designed and built a few hubs for the early cars and the 86T so any larger rotor can be installed as well. The FACT of the matter is all alloy cast hubs will eventually wear and fail due to the heat cycling and fatigue. The 86T hubs failed first because they had bigger brakes installed yet Porsche made them weaker by design to get an off-the-shelf set of calipers on the 86T.

I have been running my billet hubs for over 10K miles so far without a hitch and that is with 330mm Cayenne rotors installed on Lexus LS430 calipers....

I made a revised set of billet adapters to run the combo to0. If You have a set of my billet LS430/Boxster-S rotor adapters you can shim them to get the larger Dia, 330 Cayenne rotors on.... NA spindle of course...

I've probably had more turbo S hubs shatter than 86 hubs, but those fail as well. They are aluminum, and the metal has a limited lifespan, and will eventually shatter apart. The spindles fail as well, though like was said the early spindles and 86 are the weakest. My question is how the heck do you have a bent hub? Are you sure it is the hub and not the spindle? Typically they just shatter and crumble apart.

I have an 87 so I won't have the weak 86 hubs but I do plan on putting on xschops brake kit. I'm assuming xschops billet hubs for an 86 don't fit on the '87 so I'd have to purchase them from paragon? I guess this is mostly directed at you, xschops.

As far as the hub, I have no idea why its bent but that is the only conclusion I can come to. I have been trying to figure out a wobble that comes from the front passenger side wheel. I changed all the wheel bearings, there is no play in any of the other parts, and I cannot for the life of me get the grease cap back on. The passenger hub will not take either grease cap even though they both fit on the drivers side. I've frozen the grease cap to shrink it, I've hit it with a 3lb hammer, and I've even sanded down the hub and grease cap a bit. Nothing will get that cap in and the gaps around the grease cap seem to suggest that the hub is not perfectly round. There is also a dent on the fender which maybe suggests that the PO had an accident and the hub was effected. If anyone has ideas, please throw them at me.

I bought a used Turbo S setup and it turns out both hubs were bent. There's no visible damage and I agree it's odd too. But swapping out just the hubs made the vibration go away. And it was from a Rennlister with lots of history. Oh well...

Wondering did 968 improve any of this condion ??

i am building a track day LS1 968


but all this baill joint, and hub failure really bother me


because. you should never have to worry about this.... if you are tracking other car



but i think since 968 is last gen of 944 plateform. most of knowing problem should be adress ?

968 hubs are the same as the late hubs. If you are tracking the car, then you need to be running aftermarket control arms with replaceable ball joints, and really should be inspecting your hubs every couple of events, and for sure every time there is an off road excursion. Honestly, we mostly run oe hubs, with a few racers edge hubs thrown in the mix. On cars that have been track cars for the last 20 years, all those run RE hubs due to the years of metal fatigue and stress. The light duty de and light duty racers we run oe hubs on. We replace ball joints every 30-50 hours on track depending on how I know the car is driven. Tracking a car is great fun, but not a cheap en-devour to do properly and safely with these old cars.

So my options are to take my chances with a used hub or buy new billet hubs? I think I would rather do it right and go with the billet hubs. I assume I can't punch out the races I just installed. Is there somewhere I can just buy the races since my bearings should be just fine. Should I be looking at replacing my spindles if I'm going to be putting in new hubs?

Here is a picture of a 1986 Turbo spindle and a 1988 turbo spindle. The 88 is much stronger looking and also has a thicker rotor.
