Brake upgrades? What do you use? Options

[TorqueJunkie]

I have a 1973 914/6 conversion with 2.4 L engine(being rebuilt now), and I am running the Alloy "S" brake calipers up front. I am looking to upgrade the front brakes. Boxster calipers are cheaper than the Big reds and a bit smaller as I would like to run a 17" wheel or smaller.

Anyone have the boxster calipers installed? Which rotors did you use? Adapters?

I have an old set of Bremtek calipers that I might use if I can find some seal kits for them still.

New to these forums, but love all the stuff on this site...especially all the racing pics

Hey Torque Junkie,

For my $$, you can't beat WILWOOD brakes! On my V8 conversion 914, I'm running 12.19" x 1.25" vented Wilwood rotors ($42 on summit)

and the 4-piston Dynalite Calipers (http://www.summitracing.com/parts/WIL-120-6804/) $125.

All you have to do is find the right aluminum rotor-hat to fit your application, drill them to you bolt pattern and make a very simple caliper mounting bracket.

Don't be scared! When I mount the rotors, I use a dial indicator to get them centered within 0.005" and tighten them up.

The bracket is also TOO simple..check out my pics and see.
BTW: I did ALL this fabrication myself in my garage with only a drill press and a wire-feed welder.

With the extra Chevy engine weight + driver, my rig weighs 2800 lbs and after a hard session on the Streets of Willow Springs, the front rotor only reach 420 deg. F., while the rears run at 300 deg. F.

Enjoy,
Terry

quick question about you brake setup. what hubs and hats are you running? my 73 911t hubs are roughly 6.55" and all the rotor hats in the 8.00x7.0 rotor bolt patern are to small in the inner dia.
so i was just wondering what hubs you were running?

Hi Rick:
I'm running the same 911 hubs as in the photo of the Yellow 914. For rotor hats
I'm using Wilwood P/N 171-3758 in front and P/N 170-0764 in the rear. Per the Wilwood Drwg, the ID of these hats is 6.82". I drilled the 911 pattern holes in the hats on my drill press allowing a loose fit. Then I sandwiched the hats between the 911 hubs and my wheel adapters, snugged the nut a bit and then centered the hat/rotor assy with a dial inidcator (Harbor Freight has been selling them for $7).

I hope this helps,
Terry
