Subject:  Re: Brake rotors

Dave,

1. Check out www.fmcc.se/guson for the full procedure of the Volvo rotor conversion. I can give you some figures right away, others later this week if you want them.
Outer dia is 287 mm, thickness is 22 mm, center hole is notably SMALLER than the required 82 mm.
Bolt circle is 4.25" so I redrilled my rotors.

2 and 3 The Porsches do not have a 4.5" bolt circle. If I remember correctly they use a 130 mm bolt circle that's pretty unique in the car world. Hey, doesn't the old Beetle have a four bolt 130 mm pattern? Cal?

I have a question.

I need some dimentions of brake rotors from people who own these type of cars.

1. From a Volvo.  The one that the Europeon fellow used on his pantera.

2. From a Porsche 911 front

3. From a Porsche 928 front.

I Believe these all have the 4.5 inch bolt spacing.

What i need is.
 * The thickness of the rotor.
 * The overall diameter
 * the diameter of the center hole
 * The distance from the back of the rotor to the most front part of the
rotor. (Basically the maximum height of the rotor.)

Thanks, 

Dave "wants more brakes" D
