Same here. A little PB Blaster + hammer time and they came right out. I thought everyone who complained about this task must have been a giant wuss :dunno:

<p>I've got an hour and a half and 3 cuts so far.</p><p>&nbsp;</p><p>Neither side is out.</p>

Do you have a dremel or something with a cutting wheel (or maybe a carefully-wielded sawzall) where you can make a cut top to bottom through the metal bushing liner?

Do you not have a press of some sort? You need one of those HF ball joint presses or something. That's what I used on mine.

Cut each edge to release tension until you're just barely touching the aluminum arm. Do this in a few places. Flip, and hit with you're biggest sledge and a wrecking bar.

<p>One done:</p><p>https://www.miataturbo.net/attachmen...ine=1432323529<br />https://www.miataturbo.net/attachmen...ine=1432323529<br />https://www.miataturbo.net/attachmen...ine=1432323529</p><p>&nbsp;</p><p>Time to go to class.</p>

That suucks

Mine gave up releasing the pressure on the bottom then on the top side. I used a wire wheel to clean the inside of the diff housing bushings, looks like you might need a bit more than I did!

I've got cheap protane bushings, I hope a propane torch is enough to melt the lower mount rubber off...

It won't melt. It'll burn. Just prepare for it. And propane will be plenty.

I feel like throwing it in a coffee can full of acetone would melt it off. :dunno:

IF the rust is really quite bad you could soak it in some rust remover from Home depot to break the mechanical bond it's forming and then smack it with a hammer.

I ended up getting it. Didn't kill wheelhop as much as I wanted though.

Supposedly this should help

BEATRUSH Rear P.P.F. Performance Bar for Miata 1994-1997

I'll make one of those. Going to the drag strip at woodburn on Sunday. Ed you should come in the s2k with a for sale sign on it. Its Some huge import car show

Can you make one of those, or do you have a later subframe? I has no tabs.

I'd turn up some solid aluminum mounts, probably work better than that brace bar for the same effect.

<p>I have a 1990, does that mean it has the tabs.</p><p>&nbsp;</p>

It has zero tabs. There's a ~$100 shipped kit (ISC?) that turns it into an NB subframe, with front and rear tabs. Also has a backing plate with a giant nut welded to it so you could attach the entire NB ladder brace from the rear. The shiny black piece in this pic:

I have one for sale if you want it :) Doesn't attach to the PPF, but it does connect the dangling subframe to the chassis to really box it in.

<p>I'll probably just ghetto fab something when I get my new welder. I'll just weld something onto the subframe.</p>

I didnt melt the the plates. I just took a 4 and half inch cut off wheel and cuto the rubber off then finished with a wire brush and sanded them down.

Something in my drive line didn't like wheelhop......good thing I just won a 6 speed and 3.9 torsen.
