New Rear Calipers and Mounts, Installed the Wilwoods Options

[Matt Romanowski]

I put the Wilwoods on and ran them last weekend. Holy Cow! The car definatly stops now. I need to get used to modulating the brakes differently, but there was no indication of fade and good balance. I think the pictures explain things pretty well.....

The first is the caliper mount welded up. I am going to post this in the resources section. We can do any caliper offset for 3.5 bolt spaced calipers people want. Set up for solid or vented rotors.





This photo is everything mounted up




This is a comparison of the new brake pad to the original rear caliper




Finally, a picture of the stock size front pads in comparison to the new pad size all the way around.



And another photo of the fronts for good measure

Another source of larger master cylinders are BMW 500 and 700 series cars.

My BMW 728i had a 23mm ATE master cylinder. As Porsche shared suppliers with other European manufacturers especially the German ones, the BMW, Mercedes, Saab, Volvo and VW's share a huge ability to "mr. potato-head" parts.

I would suggest a walk through a U-Pull-R-parts salvage lot and check out the possibilities that lie with other makes.

914's and early 911's used a 3" spacing and later 911's used 3.5" spacing for the brake calipers. Take a measurements under the larger cars (as they would need bigger brakes) and find the ones that may fit. Also, you may find things that shouldn't be there. The local yard had a BMW 2002 (the manager advised the seller not to sell to him) from which I pulled a VDO electric pump windshield washer, quad piston front calipers and various other compatible parts.

Similarly, for instance, both Saabs and Volvos used Bosch electronic distributors that are very similar to the 050/009 family of distributors above the case line. One could pull one of these distributors and machine a new shaft for a 009 and fit the electronic bits on it. That alone would add considerable peace of mind.

Good Luck,
