Now I'm confused. I'm looking at some replicas but the ad says "4 inch backspacing".
What does ET40 mean? 40 mm.? Mike |

The back spacing, measured with a tape and rule, is 4 5/8" on OEM Fuchs wheels. The 5/8 makes all the dif in the world on a narrow body car, with unaltered wheel wells, and running 195 width tires.

Mike http://www.tirerack.com/wheels/tech/techpage.jsp?techid=101 Offest is an European term, backspacing is redneck (I mean American term) (IMG:style_emoticons/default/smile.gif) Backspacing is from the hub surface to the out most point of the rim. You measure this by using a straightedge across the wheel and measure... a picture will explain better than me.. |

If you notice, backspacing takes into account the thickness of the lip, offset does not.
So 2 rims with the same width and offset may have different backspacing depending on how the rims have been made. I wouldn't think it would vary by more than 1/4" to 3/8" max |

OK great info!! So I guess now I need to ask what is the "backspacing" measurement on a 4 paddle Fuchs wheel?
Thanks |

OK...I just re-read Rhodyguy's response. So a 4 inch backspace will not work? Correct? It's a narrow body car.

4"? Results may vary. IMHO, a major factor is what size tire you intend to run. You don't want to drop $$ on a wheel and tire package only to find you need to make adjustments to the chassis. Those adjustments, rolling the wheel wells or trimming the lips, will be expensive to undo.

Good point. I have almost new 195/55's now so that's what I would be using.
Don't really want to roll the quarter panels. |

I run 205 50/15 Hoosiers on the stock 2.0L Fuchs and they rubbed in the rear, on the inside, on the track (probably would NOT rub on the street).
That is with NO shims for camber (max camber). So I used 3/8" spacers and still have room on the fender side. 195s should fit with the stock rims and no spacers. Note: LONGER bolts/studs are required (even longer than the special 2.0L-Fuchs bolts) with the spacers. |
