914-6 Brake Upgrade Options

Here's my story.

I have a 914-6 that's been garaged for the past 22 yrs. The 2.4S tweaked engine is out for a quick review. The chassis has HUGE flaring with 12" rear wheels and 10.5" front wheels. I'm looking into upgrading the brake system and putting the original equip. in mothballs. Cheaper to burn up available equip.

Research has lead me to many - many options. Everything from 930 to Boxster. All of these seem to require aftermarket brackets and upgraded master cylinder. I want to do this correctly the first time.

I just spoke with the guys at 911pcar.com, the advice was to run this by you, the specialists on this forum that know whats - what with 914's and 914-6's. Wait, the direct quote was "ask the guys on pelican because they've already done what your brain is just starting to try and think of."

My 914-6 currently has OEM stock brake system. Too spongy for huge rubber tires.

Please pass some knowledge.

Thanks,

-- SouthernMan

You can swap in SC or Carrera front ends. The rears are a little more complicated. Try and contact Eric at www.pmbperformance.com

One limit is your car has 3" struts. To run "larger" brakes, ie, SC, Carrera, 930 and others, they use a 3.5" strut spacing for the caliper bolts.

While you mention massive flares, and a 2.4 S (maybe 180-200hp?), you don't mention how you use the car. Street fun? AX? Track events (where heat sink is an issue)

What diameter wheels are you running?

While I LOVE the 930 brakes on a 914, I think due to age, some of the parts are getting quite expensive. However, they can fit under 15" wheels.

If running 17" or larger wheels, 993TT brakes could be your "ultimate" set up.

I ran 84-89 Carrera rotors and calipers (front and rear) on my 914-4 with a 2056 motor (120hp). I used the car for AX and DE and thought the brakes an excellent match. More than enough power for 205 width tires. Also upgraded master cylinder.

The other issue with 914s is that they are relatively light, so they don't really *need* overly large brakes, imho.

I used 911 m calipers on my gt clone. Plenty strong enough to stop my 3.0. Also PMB has a strong caliper that bolts onto your 3 inch struts.

Really worth talking to Eric Shea at PMB Performance. He's the expert on the best brakes for these cars and developed a perfect set for me. Very reasonable prices too. Mark

I have 930 brakes on mine and love it. It does have a 19mm master cylinder. I can get my car to stop on a dime! The big vented rotors and painted callipers look cool through my 16x9 wheels.

No longer a limiting factor... in fact, I like the 3" struts better. Generally speaking, they offer more insert choices.

These are just as big (pad wise). Much lighter than SC and Carrera "PIG" calipers (the heaviest caliper Porsche ever put on a 911) and even one pound lighter than the famous S-Caliper.
