PPF Stabilizer Kit by Just Miata

“My PPF Stabilizer will improve every 1990-2005 Mazda Miata on the road”.

My kit is the one you see at MiataMania.com

I have always felt that my PPF Stabilizer Kit should be on every Mazda Miata produced from 1990 to 2005.

Effective and very easy to install.

You will notice a sharper, tighter, ride that you can feel. The Miata’s over all ride quality improves due to less vibration and power train movement from the engine to the differential of the Miata. The entire car settles down and has more solid feel that you notice. I wanted to create a part that was actually effective and was noticed once installed. My goal was a design that was simple, logical, easy to install, and made from high quality materials and built to fit every Miata on the road from 1990-2005.

I created the PPF Stabilizer Kit from my Mazda Miata customer’s vibration complaints about vibration in their Miatas while driving.

PPF is weakest just behind shifter

The Mazda Miata has a long aluminum drive train part that looks like a “trick” piece of “c channel” called the PPF. The PPF is a torque tube of sorts, that connects the rear of the transmission to the front of the differential and acts to support both pieces. There is no rear transmission support in the Miata, the PPF does this job. And, if you look closely at the front end of the PPF, just behind the shifter, there is an area of the PPF that is weak. You would think this portion of the PPF would be the strongest because it is the farthest distance from the motor mounts in front and differential mounts at the rear, but oddly it is not. The PPF performs and incredible task of supporting the weight of the transmission and all the forces placed on it by normal vehicle operation. Quite incredible.

PPF cut out around shifter.

I noticed that when I put my hands on this area of the PPF, that it could be pushed and pulled from side to side very easily. I also discovered that when the section of the PPF and the transmission were struck with my fist or rubber mallet the entire assembly would vibrate for an extended period of time. My idea was to find a way to strengthen this weak section of the PPF.

The Miata differential moves up and down and side to side very easily, so I developed a bushing that would reduce the bounce and sway of the differential. My theory is that combination of the PPF stabilizer and the differential stabilizer bushings would have a very positive effect on Miata and my theory has proven correct.

Differential bushings fill air gaps.

The Miata PPF Stabilizer Kit was designed originally for my day-to-day Mazda Miata customers to address their vibration concerns, but the performance Miata guys find real benefit using the PPF Stabilizer Kit for the control it gives their high horse power Miatas. Just ask Gary at Track Dog Racing in Texas.

All custom components of the PPF Stabilizer Kit are made in the USA.

The PPF Stabilizer Kit weighs 5.5 lbs., very easy to install, installs in 45 minutes to 1 hour with fairly basic hand tools.

    Stuart,
    Your PPF Stabilizer Kit is fantastic! My Miata handles so much tighter. It was fun before, but now even more enjoyable. I would recommend it to any Mazda Miata owner. I could feel the difference the second I drove my Miata out of your shop. Thanks again for the fantastic work you did for me.

    Stuart,
    I was thinking about your PPF Stabilizer Kit and wanted to give you some feedback. My 1996 Miata would begin to vibrate from about 66mph to 70mph, but now with the PPF Stabilizer Kit you designed my Miata is much more stable through the 66 to 70mph window. No vibrations, no shimmy.
    I also noticed that the back end of my Miata used to be a bit “skittish”, but now, with your PPF Stabilizer Kit, my Miata feels more stable in the back and rear end. As a matter of fact, the whole car feels more stable front and back. Thanks for the excellent product.

    Stuart,
    My Miata feels more stable in general, but I also noticed a nice change with your PPF Stabilizer Kit during some hard cornering. My Miata definitely feels more stable going through tight turns. It’s not as nervous.
    I also noticed a difference going over some bridges in my area, my Miata feels more solid.
    Thanks buddy!

    Stuart,
    Your PPF Stabilizer Kit really tightened up my Miata’s ride. My right foot feels more connected to the road and my 65mph “shimmy” is gone. The quality of PPF Stabilizer Kit is first rate and should last the life of the car. Highly recommended.
