Does someone have the exact length of the unequal 968 axles please?

Ps this needs to be spot on correct rather than a guess as I'm ordering a set of aftermarket heavy duty axles. 

Thought this might be the place to ask. :-)

Shoot. If you asked a little earlier, I had them out a few months ago...

Can you do without your car long enough to remove yours now and use them as templates for the replacements?

if you change the length, i have a set of rear aluminum hats that would work on the car, and allow for larger floating rotors.  the fronts aluminum hats will fit fine as is.  just thinking

Thanks Bob but the rears already are full floating, vented brakes. This is a 944 track car with a 968 trans. I have these aftermarket stock unequal length axles in it now and just want to buy a backup set. It's just as they're in the car I don't want to have to take them out to measure them. Just don't want to get to the track and not have a backup set of these CV's and axles on the 'just in case' principle. They cost about $1200 for the axles and CVs but it's better than not being able to turn a lap at all if either component brakes. New motor should be capable of 800hp+ so I don't know what will happen to the driveline. Luckily we don't do any hard launches. All rolling starts.

800+? Holy shit! Is it a Turbo?

out of curiosity for the less informed as myself included, what are floating brakes, and what are all those stainless lines around the rear end?

Floating or 2 piece rotors are when instead of a one piece rotor that includes the hat, the hats are separate from the rotor and connected with fasteners or whatever the terminology is in the US. In the first pic you see the Big Red calipers with the oem Porsche 322mm 1 piece rotor. The 2nd pic shows what has eventually wound up on our car with 2 piece floating / slotted 375mm rotors and Alcon 6 piston monoblock calipers. They tend to fill the 18" wheels up quite a lot now. 

 

The stainless lines have replaced the stock hardlines for the rear brakes. The weight saving on the rear between the fixed rotor and the 2 piece. 1kg = 2.2lbs of unsprung weight. I don't know what the weight difference is between a single front 1 piece rotor and our current ones but they'd be pretty similar even though current ones are much larger.

800+? Holy s***! Is it a Turbo?

Yes, custom 3.2ltr 16v turbo starting with a 968 block. I have a couple of friends who have hit approx 675whp with their motors and I think ours will be at least as productive. Remember I was quoting 800 bhp not whp.

I've been told that the axles are 525mm and 560mm. Happy to have someone else confirm this.

Those are pretty sweet stoppers. But I guess you need them bad with that many horses pulling the wagon ;-)

No point to oversize brakes if they're not needed but in this case they definitely are.
