    I was just literally quoting Bob, but what I think he means was - there aren't any knock-on replacement hubs available for XJ40 uprights, so you have to use a "two piece" hub; the original XJ40 hub and then the knock-on adapter.. that means you can't have (really any) dish at the front, and the HAs aren't available with that little dish for the front.

    Rears aren't so much of a problem, you just end up with less dish than normal, but the front already had almost none and with the hub adapters properly has none..

    Hi Aaron...

    Bobs a good guy and he knows his stuff around fitting knock ons to Jag cars as plenty of us have bought from him.

    The HA's are a cast one piece wheel. They are a direct copy of the original in that respect, but the only backspace flexibility is what you can machine off the rear face.

    On the rear you don't end up with less dish, instead Bob machines the thickness of your adaptor plate off the rear of the wheel to give you more backspacing. The issue will be there isn't enough meat to machine this off the front wheels. The pic attached is a front HA photographed from the rear. The adaptors are usually around 10mm thick (Bobs maybe 0.5"/12.7mm being American?). You can see that's tight to machine off.

    I'm guessing the 427s are assembled wheels and this gives him some flexibility to change the backspacing. Nice wheels

    Yeah, exactly what you say, Lloyd, I believe.. it's a shame as I love the look of the HA's! I will have to 'slum it' with 427s, though

    You can see how little dish you end up with on the front here, on Kev's car: http://www.cobraclub.com/forum/showt...256#post573256

    Look, you already made a public statement (albeit some years a go) that it was going to be banana-skin yellow.
    C'mon, honour your previous commitment, my Granny always said.
