Boxster axles Options

[partwerks]

From what I understood the 5 speed Boxster trans, the axles were two different lengths. At the start he said the axles fit, I thought something didn't seem right, but now that we finally got to doing the wheel alignment, I was correct in that the passenger side is too short. He said about 1/2".

Does anyone know what the correct length of axle would be on the passenger side using the 5 speed Boxster trans, and if so, where I can acquire one at?

My setup is totally custom. I run 930CV's with both my 6 and 5 speed. My 5 speed has custom 108mm stubs. I use the same axles on both with the addition of a 7/16 CV spacer that doubles at the magnetic speedo pickup.

I purchased multiple axle lengths until I found the sweet spot.

I run non-plunging CV's. This requires me to run sliding axles. (normal CV are plunging with fixed axles).

I fine tuned my setup to work with either tranny.

I spoke to Lyle and I'm not convinced that his mechanic have the skills to complete this build. I base this on some of the basic component setup confusion on his part.


If there is an "easy" way... Make your build use the same size CV for both the inner and outer. Then buy the correct length axles. They will be about 3/4"-1" different in length.

Remove the rear wheel and disconnect the shock. This will allow you to easily raise and lower the suspension until you find the closest distance between the tranny and wheel hub. Take this shortest measurement and subtract 1/2" this is your maximum axle length. Then buy axles with a spline count that matches your CV's.

If you have 100mm CV's, you spline count most likely is 33. If you run 108mm CV's you spline count is 28. If both CV's match, axles can be purchased off the shelf. If you need 33 on one side and 28 on the other, this requires a custom machined axle.

If you have a 5 speed, this is 100mm. If you have a 6 speed, this is 108mm.
