I think you got punked- "made for Slee before they started selling them" seriously I wouldn't believe that statement. Slee spacers were always Blue anodized (looks like black now) Anyway If not hub centric on the front, then you need to tighten the lugs with the wheel off the ground to avoid wobbles.
What did you pay for them? $100? Honestly- If safety for you and others is any concern, a set of Bora or Spidertrax spacers are the only choice - and for a little more than $200 for a set of Bora spacers why bother with an unknown used improper fitting part?
