Caliper Porn..., ...silver, plus a peek at GT calipers Options

One lucky tattoo'd teener has his eyes on this set and wanted me to post a picture when they were done. This is a matched set of front (yes I do fronts) and rear calipers. Done in the very chic silver (clear zinc) with gold accents.

On to the questions:

A stock -4 rear piston is 35mm. A -6 rear piston is 38mm. So yes, they're bigger. Thay are the same size as the 911 rear piston of the same era. This is why they matched them up with standard 911 M-calipers up front. The calipers almost look identical side by side but the -6 is a little larger.

I'm not certain but I believe the front 914 is 43mm (just finished the last core I have here and it's hard to get a measurement with the dust covers on.) Things that you would have to do:

Enlarge the bore by 5mm (you've now lost the step to seal the dust cover to).
Regroove the new bore for the piston seal.
Remove the dampening mechanism from the -4 pistons.
Machine a ring groove in the -4 piston.
Machine a new spider to attach to the adjustment screw bore.
Find a snap ring to fit on the new spider and fit into the groove.
Find a way to attach the dust cover.

Short answers:

1. There's not enought meat there.
2. I don't think the -4 piston can be modified.

Auuuuuuuuuuuhhhhhhhhhh bottom line, it would be easier to match up the proper rear caliper that comes with whatever front caliper you'd be using than it would to machine a uber rare -6 caliper. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
