The fact that your statement is solely based off of speculation is why I almost want to quit posting on here. Please do yourself a favor and read the thread again. I pointed out the issues that need to be dealt with before even running new axles, reduced angle or not.

As an update, I have been very successful running these axles on my car. I am fairly aggressive on the street and they are handling the torque of the V8 nicely. When my suspension comes in, I WILL be tracking this car and plan on leaving these axles in.

As also mentioned earlier in this thread, if you are scared like this individual, then pay some extra money and get the stronger ones that xschop provides. Those should be close to bullet proof and are far cheaper than most retailers of these rebuilt and upgraded axles.

I appreciate the new information provided on how much the axles will deflect. But I am wondering how you can get an actual number of a car in motion on the track where things tend to move differently than if you just jack up one side of the car. What is the basis for these numbers?

I wouldn't say that would make the axles stronger, but I do feel that Porsche stumbled upon a nice source of axles that were 25 spline and went with it. I'm pretty sure that all models after the 85.5 split should be able to run these axles. Any car that had aluminum trailing arms should be in that category. I will have to research it more, but I am pretty sure any late model can interchange between the 33 spline and 25 spline axles. If you don't mind waiting a week, I'll be back from vacation and can see if I was in fact running a 25 spline before I swapped in these and I will even get measurements just to be sure.

The original reason I ordered these was to swap the new joints over to the old axle shaft, which match the 33 splines. It would have been cheaper to order the whole axles themselves than to order individual joints. The ones partsgeek sent me happened to be the same length as stock, so I just installed them. The axle shafts that come with these are solid, heat treated, and are thicker than stock.

As mentioned in my post, measurements were taken on my lift. The total upward deflection is my best guess, based on the fact that if the wheel moves up more than 2 inches from it's static position, the tire would rub the inside of the fender, which it does not while on track.

To get the greatest upward deflection, you will need to remove the spring and jack the wheel up till you hit the bump stop. This would be the max angle, whether measured on the lift or on the track. Max droop on the lift is the max, the wheel is hanging and it isn't going to go any lower on the track.

My race car is lowered, and hence the +5 degree angle on the axle when the car is just sitting. The more you lower your car, the greater the angle will be. However, I doubt that most daily drivers are lowered more than my race car. I'll measure the angle on my daily driver 968 and see where it's at in the static position.

I'll throw the axle on the car for the next DE and give it hell for you guys.

Just an update. I have been daily driving with these axles on. They have seen quite a bit of abuse (with the occasional "accidental" slide :D ) and still remain solid.

That link doesn't link to the part # quoted (90-6805).

Google works and I see them on amazon and other places. So far I have $75 shipped... is that the best one can do?

*edit*

shipped from rockauto with discount 92015847578143 is $66.67... That's not ominous...

*edit*
63.xx shipped from impartpartsguy... $55 if you order over $149 and get free shipping...
