5x112 conversion. The other way.

[mdz]

Redrill 4x108 to 5x112. One of the holes nearly matches, rest must be drilled. Material is soft, drills easily. Or you can surf through a brake parts manufacturers catalog, there should be disc parameters listed and compare them (diameter, thickness, hat height), maybe S2 discs does fit in your case.

The diameter of the S2 disc is 276mm, which is 4mm less than my orginals, and the thickness is 3mm more. So theoretically with a less thick brake pad, i think it would be possible to assemble.

Guys, im about to do the 5x112 conversion on a 94 2.6 v6 quattro avant ive just bought. Ive got a set of s2 hubs & brakes for the front, just trying to confirm that for the rears a B5 front hub wont fit? I can get a 2.5tdi quattro front hub for a lot cheaper than the rear ones!

Also will the bearing thats already on the car fit the new hubs? or do i need a new bearing as well? Cheers

Front spline is 38 teeth, rear is 33 teeth.
So no, the front hubs aren't a match for the rear...

B5 quattro rear hubs fit a coupe but I'm not sure about an Avant...

[struikie]

Avant has the 82mm bearings on the rear vs the 75mm of coupe and sedan.
B5 quattro sedan rear hubs do fit, but have a different offset.

JW

[M2ki]

B5 quattro rear hubs don't fit, they are for a 75mm bearing, even the RS4 ones.
B4 V6 avant, S2 sedan/avant and RS2 all have 82mm bearing in the rear.

[struikie]

Have to disagree.
My 1993 80 B4 sedan V6 quattro has 75mm rear bearings...

JW

edit: didn't catch the question about the avant. Yes, avant has 82mm bearings in the front and rear.
Autewo.de has conversion hubs available for both bearing sizes.

Bumping up this old thread in the hope someone can provide a little more detailed instructions on the following as i've just acquired a set of C4 hubs to fit to the front of my B4 80 Quattro

C4A6 quattro rear and B4 front are identical except for one thing. "All you have to do is machine down bit of metal in the middle"

Anyone have pics and or instructions on how much and where you machine down?

Appreciated.
