    FAST, Is 4.25\" Backspacing going to be too much?

    As the title of the post says. I need to know quickly if 4.25" of backspacing is going to be too much. 15x10" wheel. Front calipers already ground some.
    Just got a call on the phone. They also have a set of 2.75" BS.
    Which one should I go with?
    Thanks guys.

    I'd go 2.75" witht he 4.5s up front you will rub your tre's and I have seen two tires almost eating away on the sidewall from steering rubbing, your 15.5 wides will need all the clearance they can get. Plus a wider stand never hurt no one. Also with the tire out farther the tire will rub before the body will /forums/images/graemlins/peace.gif

    I will tell you as soon as I order mine. They have one set right now, but they can get more at another warehouse. I will let you know soon. /forums/images/graemlins/rotfl.gif /forums/images/graemlins/thumb.gif

    I think I have 4.25" bs on my MT Classic II's. No rubbing TRE
    but I have the d60 and the wheels ar 16x10

    If I had 2.75 bs I think my tires would hit the fenders under flex. As it is now they stuff up into the well nicely and the tire don't stick out too much. Check the pics in my link.

    Thanks guys, the concerns about the wheels hitting the TRE's was enough to make me go with the 2.75"s. I got a set of 5 15x10" w/ 2.75" BS delivered to my house for $312 from Sportz Trailers
    They were really helpful people and took their time with me and were prompt with callbacks and everything. Very professional. /forums/images/graemlins/thumb.gif

    The new lift/axles/brake system/wheels/tires/electrical system/bumpers should be finished in the next couple of weeks. I will post before and after pics of the transformation. /forums/images/graemlins/thumb.gif
