on the front rotor, indexing it would interfer with the webing on the inside, not a modification I'd want to have to do to all 4 webs.
the rear flanges I had a buddy do at a shop, he should have indexed the new holes 45°, that way the rear rotors wouldn't be that big of deal..... |

On those rims that Jon showed a pic of, they are called dual pattern.
One is the 100mmX4 VW/honda pattern, what is the other? |

Anyone know if our front rotors are shared with the '66-'79 VW beetle/ghia?? They look the same. If so, then you can just buy 4x100 front rotors. You can also buy native 5x130 front rotors:
custom VW rotors I'm guessing they are probably not the same or someone would have done this long ago. But ff they are the same, then this is the way to go. The rears are easy since the pattern can be indexed by 45 degrees. Demick |

Wish they were the same because you can get blank rotors. |

Knock off working on the hubs and make some rear trailing arm needle bearing kits... (IMG:style_emoticons/default/biggrin.gif) My car has requested one set. |

QUOTE(Mueller @ May 10 2004, 10:48 AM) 10mm how?? Diameter or ??? The wheel face to the disc face, the 914 disc part sits back 10mm more. (I called this the backspace in the specs below.) This is approximate as I did it with a tape measure. There "could" be other differences, I didn't check. I have a new ghia rotor, right here in front of me, if you want all the specs. I don't have a 914 rotor off (or new) to check the specs on the race seats, etc. |

The back, notice no reinforcement ribs, the casting is thicker in this area so a blank can be drilled in almost any pattern.
