    Good Morning,

    At this point I feel like a broken record with wheel questions but here goes...

    Bought 4 American Racing Ansen Sprints, which these guys happily sold to me during a 10% off sale but have now informed me that they are backordered with no estimate of arrival due to covid. To frustrate me further I have already purchased some BF Radial TA's 205/60/15 for the front and 235/60/15 for the rear.

    Ansen Sprints - 5"x7", 0 Offset, 5X114.3 Bolt Pattern, 83.06mm Center Bore

    My questions is, how important is center bore size? The US Indy Slots they claim to have in stock look very similar to the Ansens but have less backspacing @ 3.75" and a center bore of 72.56 mm. Is the quality of these as good as the American Racing?

    I currently have rear and front drums with a stock suspension and have the parts for a future granada disc conversion or will buy a Wilwood 140-13477 disc conversion kit and sell the granada spindles.

    US Indy Slots - 15"x7", -5 Offset, 5X114.3 Bolt Pattern, 72.56mm Center Bore

    So ultimately will the US Indy's fit just as well or wait out for the Ansens to come back in stock.

    Thanks in advance for your advice and input!

    Check your front drum hub/rear axle size, on our Mav/Comets they where either 2.43"(61.72mm) or 2.78" (70.61mm) so any of mentioned rims will not interfere with hub/resister and even with Granada set up. So long as you use lugnuts with 60* cone, will center the rims on the wheel studs/spindle/axle. I have the Ansen Sprints 15 x 7 on front and 15 x 8 on rears..........
    Your tire sizes will fit just fine with any of those rims!

    Thank you - was confused over the nomenclature, got out the calipers and measured the diameter of the hub on the new granada rotors which came out to 70.6 mm. Makes much more sense now, just needed to visualize it.

    To add what was indicated above - Wilwood tech guy says their rotor hub on the 140-13477 kit is 2.645" dia.
