    Question Wheel quesstion

    Brian:
    Prior to placing an order for wheels and tires I would like to double check the appropriate sizing. I am looking at 18" X 9" front, 18" X10" rear.
    I have a Mk IV base kit, standard width, with FFR front spindles, and IRS for the rear using Cobra hubs.
    From page 465 of the complete kit manual (which I have on my computer) it looks like the proper backspacing for the front is 6", and for the rear it is 6.8".

    Does that match what you believe is appropriate?

    TIA
    CL
    Confidence: The feeling you have before you truly understand the situation. FFR 7652 Mk IV Base Kit w/IRS: ordered 10/19/2011; Arrived 11/19/2011. Coyote, Trans & headers Installed 9/11/17. First Start 12/19/17, First Go-cart 3/2/18. Aligned and go-karting. Working the interior now. Happy customer of FFR, North RaceCars, Forte's, and Breeze.

    CL,

    The front wheels should have a 6" back space and the rear wheels should have a 6.25" back space.

    Best regards,
