  1. Here's a shot of the Borrani. You can see how broad the original aluminum (?) rim is. I am talking to Dayton right now about lacing their aluminum rims to use a hub that can work with the knock off adaptor that fits a Z. I'll post when I get the info.

     

    The second photo shows the reverse lace that is needed to get the offset needed to fill the well and handle those tires.

     

    By the way - great tip on ordering through a dealer...Thanks.

  2. Mike,

     

    It was brought up on another thread regarding the difficulty of getting hubs that real Borranis will fit on. ..which is the most authentic look. But it has been done (see photo.) This car belongs/belong to Philip Gaulin and used a Scorpion Z-car kit to create his 250 GTO replica - its running real Borranis. (If any one here knows him, it'd be great to hear how he mounted them on the car.)

     

    Thew other thing about this look is that Borranis are painted silver, or are in the raw aluminium. None of the original GTOs had chrome rims. And many of the repalcement rims are chrome.

     

    Last point: real Borranis are expensive. I've been trying to source used ones but even thay are ~600 - 1000 each, unless you can find them at a swap meet. The original style are also not very reliable on the street from what I understand. Read: http://tinyurl.com/eat6k Also note: that the Daytons in the link are Borrani replicas with aluminum, not the steel rims a lot of folks run.

     

    Are you planning on running Daytons if you can't get the other rim companies to come through?

  3. Has anyone successfully dropped a 1976 280z 3-4 inches?

     

    Per the info above the the stock wheel hub center height on a 280z is approximate 12.4 where as the stock for the Ferrari is rear hub is centered ~14.7 inches high. In the front the correct height tires 26.6 vs datsuns 25.16 so the front hub is centered 13.3.. vs. 12.6.. or ~.75 inches higher on the stock GTO.

     

    So putting the original height ferrari tires on any rim will raise the Z two inches in back and .75 in front.

     

    I would like to overall lower the car 1 - 2" while putting the larger diameter tires on it. So this means dropping three to four inches in back and 2-3" in front

     

    Has any one succesfully done this? (I've seen a number of thread referign to dropping it one inch.)

  4. Some info on wheels and tires that might be useful to others.

     

    It would be interesting to hear about the wheel and tire specs that others GTO's are running...particularly regarding 15 inch rim tire combos, sizes and brands.
