I have 4 Forgeline RS wheels for sale. These were used as race rims and have some pits and such in the finish from track use. They are not show condition wheels, but are in good shape (round and lightweight). 2 wheels are 17x11's and 2 are 17x9.5's. I bought these to run on my car and have decided not to use them (and I need the space in my garage back, I've got 3 sets of wheels and this set of rims in my garage at this time). I'm only asking what I have in them (the retail price on these are about $2000 for the set of four).
$650 plus freight (they are still boxed up in my garage). |

He ran into something and needed to hang onto his cash for a while. I can measure the backspacing for you and post it here. |

17x9.5 = 6 7/8" backspacing

Convert the rim width to mm, then convert the backspacing to mm, subtract one from the other.

11's
279.4 mm = 11" 212.725 backspacing = 8 3/16 66.675 offset for 11's 9.5's 241.3 = 9.5" 174.625 backspacing = 6 7/8 66.675 offset Does that look right to you? 25.4mm per inch |

I was getting 41mm for the fronts and 55mm for the backs, seams kinda off. Did you have these on your fbody before, if not what kinda car were they used/made for?

I've never run them, I bought them used and decided not to run them. I did test fit the rear wheel on my F-body and it looks like it will fit with no problems. You could pull your wheel and measure the backspacing. We can convert that to MM and see if it is within tolerances. That may be the most accurate way (since I'm not sure that either of us figured that correctly). |

Im not as worried about the fit as I am them being legal. My car is run in A-Stock and I need a 17x9.5 w/ 56mm front and 17x11 50mm in the rear. Rules say that I can go +/-.25 of an inch, but thats all. I would measure my 17x9.5's, but I don't have any 17x11's to look at. Offset for the front should be at 2.2 and the rears at almost 2 inches.

I knew you were worried about being legal, that's why I was thinking we could measure what you have, I didn't know you didn't have any 11's. Hmmm....

Yeah, I did my oz's which i know are a 17x9 56mm offset and came out w/ 57mm, close enough. And I did all the math the same way we are doing these.
I need it to be around 9inchs deep for the rears and 7.3 for the front. |

We need to be +/- 6.35mm by my math.
Did you measure and calcutate a set of known wheels? Is that what you were saying? |

Yeah, when I measured them I came out w/ 57mm after doing the math. The wheel has 56mm printed on it which is the stock vette size.

I layed a steel straight edge (yard stick) across them and measured with a brand new (unstretched) tape measure. I'm sure they are the right numbers.

Just checking, 66mm just seams like a high and strange offset number to me. Thats almost a third of an inch from stock and seams like it would cause some rubbing, i dunno....

I'm going to guess that your math is correct and mine is not. And, if you just calculated known wheels and it worked, I'm going to trust your numbers more than my own.

My Math
9.5- 6 7/8=2.63 * 25.4 =66.6mm 11-8 3/16=2.813 * 25.4=71mm |

Hmmm. He said he ran a small spacer on the rear, but when I test fit them, I didn't see where it was needed (actually, it may have stuck the wheels out past my fender to space them much at all, but firebirds have or seem to have wider fenders).

I don't see how they would have stuck out, wouldnt the 71mm offset be more sunk in than the standard 50mm?

I meant that they would stick out with a spacer (such as a 3/8ths). They look to fit "perfect" on my car as is (I didn't have tires on them at the time) and seemed to be right where I expected them to fit.

For the backs to be legal I would need over a 3/4 spacer. As much as I hate to say it, but I think im going to have to pass. Unless for some freak reason you got your original numbers wrong, these aren't going to work for me.

Interested in the math here...
isn't offset calculated from the centerline of the rim? http://www.usacomp.com/Offset.htm |

Ok. Now that I'm awake, I just refigured it. The specs are:
F: 17x9.5 60.325mm backspacing R: 17x11 68.2625mm backspacing I think the math works on those numbers. I was figuring 3/16 as 3/8ths last night among other problems..... |

I think the fronts may be legal, the rear may need a 13mm (1/2") spacer to be legal. Based on a tolerance of 6.35mm (.25"). You needed a 56mm front, these are 60.325. The rears are 68.2625mm and you need 50mm, so a 1/2" spacer would get you "there". That makes more sense. |

I still think im going to pass. I would need to run a big spacer just to be legal, and if anything I wanted to leave room for a 1/4" spacer on top of the stock 50mm offset in case I have clearance issues w/ the 335's. I wish you were a little closer so that I could throw them on and see just how much clearance I would have, ow well..

According to my rough calculations I get that the fronts are 42mm offset and the rears are 56mm.
See this site for a good visual reference: http://www.skulte.com/adapterfaq.html A 50mm 17x11 has 7.93" of backspacing. so if yours measures 8 3/16"; that is about 1/4" more or 56mm A 38mm offset 17x9.5 has 6.7" of backspacing. so yours measures 6 7/8"; that is about 3/16" more or about 42mm.
