They look like a good idea to protecting our pinch welds.

To good to be true?

I use hockey pucks.

tough mothafuckas, 5 years and going

This is what I use as well. Hockey puck ftw. and it's also super nice for jacking on any subframe.

Flyin miata makes something else that would be a cheap alternative
Hockey pucks do work as well though

These guys just took some 80/20 (knock-off probably) and cut it into 4" sections and are marking up the hell out of it!

The hockey puck method works well, just cut a slot into a few pucks.

Hockey pucks here too.
The only potential problem with the FM tool is that not all pinch weld heights are the same.
Not sure how the speeds compare to the 90-05 miatas but FM does mention that it may not work on 09+ mx-5s

2x4

I have the one from habour freight. On my gen juan, the pinch weld heights are not the same on both sides, so it doesn't work as well.

That's all I'eve ever used. Lol.

Same Here, easy and quick

I must be the only one that doesn't give a fuck and jacks the shit using the pinch weld. My car has been lifted plenty of times and there isn't any real bending going on.

These seem similar to the FM. They 5/8" depth, which is about right for the inside of the crimp, but the outside is more like 1".

Like @IMASA, stated the distance from the bottom of the weld to the frame varies.

LOL!

To be fair you don't live in the rust belt.

I do, hasn't been a problem for me jacking the pinch welds directly. I do have a few hockey pucks kicking around that I'll use if I need to be a bit more delicate on a vehicle but it's rare.

The lifts at most garages aren't much/any better most of the time.

True story

Yeah I never thought people used anything but a 2x4. Seems like a waste...


Tapawhat

I guess a 2x4 would be the easiest to create a groove in, and cheap as dirt.

But I have also seen wood split when a groove is created.

This.

I wouldn't use wood either.

Yea, using wood is actually dangerous. It can split the car comes tumbling down.

small pieces of 80/20 can be had cheaper than those little adapters.

I like the hockey puck idea and will see what I can track down but finding them locally is a challenge in KS.

Wood is fine if you keep two things in mind:
(1) Don't use pine or any other very soft wood, start at Poplar and work your way to harder species.
(2) Cut or router your groove across the grain not with the grain and you'll have much lower chances of splitting.

Cutting across the grain is the most important factor.

Went with a hockey puck, mostly because the guy selling the specialty ones never got back to me.

It was a bit challenging to get the right bit for the Dremel, and making the groove wasn't as easy as I thought it would be. Looks like crap, but seems to work fine.

Cost me $1.99, not counting the $45 Dremel. LOL!

I bought a 'hockey puck" style one off of ebay or something. Seems to work fine.
