914/6 rear caliper spacers, one solution Options

[michel richard]

In the process of restoring my 914/6, I want to have vented rear rotors, mostly because I'm going to have a big engine, but also because I think it's kinda cool.

The stash of parts I bought from Jon Lowe contained some rebuilt original 914/6 rear calipers.

It also contained some good condition 911 front calipers "A" calipers I think: 3 inch bolt spacing, steel, and with a spacer. They had 48 mm pistons.

To build rear calipers that have a spacer, there is one recipe that uses the spacers from the rear of 911 mid-year calipers, as well as other hardware. Those spacers are 10 mm. I don,t have such calipers and initial attempts at getting some were unfruitlful.

So, I took the spacers from the front calipers that I have, but they're 7.5 mm thick.

why don't you just order one of Eric's kits?

-4 and -6 calipers are different.

I guess I'd look at sourcing the next size OEM, and drilling and tapping.

It's really simple gang... get some core 'Rear 911 M-Calipers' Virtually everything you need is simply 'there'. Here's what it takes to do this conversion (detailed list)

*10mm Caliper Spacers (included, exact match in the rear 911 m-caliper)
*Longer Hardware (included, exact match in the rear 911 m-caliper)
*5mm Rotor Spacer (we can supply, they're not cheap but not too bad)
*Custom Pins (Michel has this sorted... for others plan on about $12-15 each at a decent machine shop)
*911 Rear Pad Spring Kit
*Longer Studs for the rear hubs (to accomodate the rotor spacer)

Now, consider how much it costs to get my V-Caliper kit, and I'm not raping anyone here... a pair of core 911 M-Calipers should go for $40-70 bucks. Think about it... $40-70 for 4 correct spacer and 8 correct bolts.

No brainer... it would be worth $100 or more to me if I wanted to do this to a -6 caliper.
