Porsche 914-6/GT Rear Caliper Conversion Bundle

 The 914-6 and 914-6/GT caliper is back! - In stock and ready to ship.

For years, doing a proper big brake conversion on the 914 was an extremely difficult task. You'd either end up with big 48mm 911 front calipers with small 33mm stock rear calipers, (upsetting your factory brake bias), 911 front and rear calipers, (losing your vital parking brake), or you'd have to pay thousands of dollars for Factory 914-6 or modified Ferrari 308 calipers. Yikes!

Along comes the "PMB Solution!" We took a set of factory original 914-6/GT Calipers and had our new casting made to exacting OE specifications. Everything from the caliper body to the internal adjusters is brand new, freshly cast, precisely machined, and ready to go on your car. 

The Factory 914-6/GT style rear is the same caliper that was on the back of the Le Mans winning car in 1970. It provides two main benefits.

The first and most important benefit is the ability to retain a factory brake bias with any of the 911's 48mm piston front calipers. Anything from the humble M-caliper to the S-Caliper or A-Caliper will match up with these perfectly in the rear. The piston size versus a stock 914-4 rear grows from 33mm to 38mm, just like the rear of a 911. Retaining your factory bias also means that your brake pressure regulator will continue to function perfectly.

Next comes the larger pad that is found on the 911's and 914-6 calipers. This larger surface area equates to better stopping power.  The same size rear pad that stopped the 914-6/GT, the venerable 911RS and the early 930 Turbos!

The third benefit of these calipers is the ability to run a 20mm vented rear rotor. If you're driving your car hard on track, or even in the backroads, sometimes a solid rotor just doesn't cut it for heat dissipation. A vented rotor will completely solve that problem and make sure that your pedal stays firm and your brakes don't fade. 

That's not all though, get ready to bundle up and save cold hard cash! Other components include:

• 20mm Custom Trimmed Vented Rear Brake Rotor
  • Our custom 20mm rotor is machined to alleviate clearance issues without rubbing.
• PMB-C Extreme Street/Autocross Brake Pads
  • Our Proprietary PMB-C Brake Pads are G/G Friction rated, which is the absolute highest friction rating available for any street pad! They also have the benefit of low noise, low dust, and durability. 
• Exclusive 914-6/GT Hardware Kit 
  
  • Brand new brake pad hardware pins and springs designed specifically by PMB Performance to work with pads that take either large or small pin styles. 
• Custom 914-6/GT Rear Mounting Kit
  • Our custom mounting hardware spaces the calipers 5mm inboard, allowing them to clear our modified 911 rotor offset with ease! 

With everything all bundled up, you get a slick $100 discount and every single thing you need to complete your big brake upgrade!

PLEASE NOTE: THIS KIT REQUIRES YOUR CAR BE CONVERTED TO 5x130 WITH A NEW OR MODIFIED REAR HUB. 

IT IS RECOMMENDED YOU GRIND DOWN THE INNER ADJUSTER FLANGE ON YOUR TRAILING ARM PRIOR TO MOUNTING.
