    521-5873P is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Ultra octane 521 I'm restoring my 84 C10 and was looking for the right wheel for it. My stock rallies were rusty and beat up. The Octane 521's had the 5 x 5 bolt pattern I needed, weigh 19 pounds, have that great muscle truck look at a sweet price. I'm very happy with how it turned out. Especially with the McGard lug nuts! I love my squarebody's new look. Thanks JEGS

    Based on the width and backspacing on this wheel you shouldn't have any fitment issues.

    I was wanting to put a set of these on a 2002 Pontiac trans am ws6 will these fit ??

    Asked by: Big dawwg
    These wheels will not fit the Trans-AM you need a 5 on 4.75" bolt circle wheel. you will also need to check brake clearance ans the 15x8 is probably to small to fit.
