    there could be lots of money in a wheel hop solution at a price point near your other vehicles solutions...

    Re: Gforce Engineering half shafts

    So if I was to design and make just the axle shafts that you could swap out yourselves (the kit would only be the axle shafts and not the inner or outer stubs and cv joints) could I base them off of 04 half shafts ? Are they all the same as far as axle spline diameter and spline count?

    The 04-05 half-shaft assemblies (inclusive of inter and outer stubs and CV jonts) are interchangeable with the 06-07 half-shaft assemblies.

    The 04-05 shafts are 1.25 inches in diameter (hollow) and the 06-07 shafts are 1.5 inches in diameter (also hollow). So some sub-component must be different.

    I have a set of each (05s & 07s). (I now run the Hendrix-Engineering axles).

    So your saying the inner and outer stubs are all the same?
    Hollow huh? Well, mine wont be hollow. They will be solid 300m, the strongest steel you can use to make axles with.

    Re: Gforce Engineering half shafts

    One of the solutions used in the 09 V's is to have different torsional spring rates on the different half shafts. This seems to reduce wheel hop. Do you have plans to use different materials, sizes, heat treatments,etc to achieve different spring rates on the half shafts ?

    I think the inner and outer stubs must be the same, but I am drawing that conclusion simply from the fact that my 05 CTS-V came with (obviously) the 05 assemblies, which were replaced with the 07 assemblies with no other changes in associated hardware or parts. This means that the inners fit into the same differential and the outers work with the same knuckles. The shafts themselves, however, were two different diameters (1.25" vs. 1.50") which means there must be a different interface between each inner stub and each outer stub, right? (I have never disassembled any of these).

    Yes, I will more then likely offer a 30mm (1.18-1.20) drivers side axle and a 36mm (1.42-1.45) axle on the passenger side.
    That is what I am coming out with for the new Camaro and G8.
    Very similar to what GM has done on the new Camaro.

    I'm sure the splined are of the axles are the same where they go into the stubs. They probably just bump up the diameter between the cv's.

    If you say so. I have already told you more than I know on this subject.

    Doubt he can really put a time on it... He will need to do R&D, lets give the kind man some time here!!! We all want to eliminate wheel hop for under 2 grand.... My money says that these wont need a $200 grease option. I cant wait to see what happens!!!

    Holy smokes...I would have been happy with a diff that would handle 500 rwhp, to say nothing about 600 or more.

    Also, I'd start raising an eyebrow at the transmission at those power levels, for they far exceed the rated specs.

    All I can say is, I want a ride in your cars...
    Haha, your funny
    Actually, I think 500rwhp would be my limit (if I ever get that far). I'm much more interested in the low end grunt . But I would like that 100hp buffer.
