Write-Up: Hockey Puck & Casting Front/Side Motor Mounts

I'm not aware of any particular brand, especially being better than the other. Hockey pucks have to follow standards so the game is able to be played fairly. Any old kind should do!

Just never held a puck is it plastic rubber or some kind of hard materials

It's a real hard rubber basically. Not sure what kind.

Im going to order some from amazon its just so many to choose from n I dont want to waste money on something like that

If youve spent more than $2 each youve spent too much lol

Check out sports authority if you've got one in your area. They are super cheap.

Lol exactly so therefore, i am being cautious

Got my front mount curing right now. It's pretty sloppy, but I made sure to get all of the air bubbles out at least. I'll probably go back with a razor once it's hardened to clean it up. Will start doing the other mounts when I feel like it.

Well, no real difference in handling. I did find that if I go WOT at around 30mph the tires will actually chirp when it downshifts to first. It also feels like the car squats a little more when it goes.

Mounts won't affect the handling so much, only the throttle reponse (this causes the squatting feeling). You'll notice more of the effect of you do the rear mount.

I'm doing another mount tomorrow probably. Not sure if I want to go to the effort to do the rear even if it will be the most noticeable. I'd rather do the side one since it's pretty easy to get off.

Update: Welp, side one is curing now. I can already see that I probably won't notice it. There's not much air space to begin with. I think that I'll do the rear one on Friday.

I will say this though. Buy a box of rubber gloves and a couple of small junky flat blades. My method was to cut open the tube of window weld, get a big glob on my gloved finger, pack it in, and repeat. Then when I couldn't pack any more I would use the flat blade to shove it all down as far as I could. When it was fully packed I dragged the side of my finger all around it without changing direction to smooth it out. Once I got this method down my mount looked a million times better. Still not the quality of something that was cast with the right stuff, but better.

Update: Side one is in. I didn't notice any decrease in engine rotation, but I did notice more vibration. Will report back when I go to do the third one.

Alright so I got to really test my 2 mounts today. I will say they made a noticeable improvement. I can spin through the bottom half of first now, and launches from a stop/slow speeds are just plain fun. The car just squats and goes. I need to do that third mount now...

1st and 2nd gears are really fun with solid mounts. The car feels like it has a race engine. With stock mounts, locking out these gears feels like something might break. There's more vibration in the cabin, but you get used to it. The rear mount will make more vibration noticeable in the steering wheel.

FYI here's an updated design on the hockey puck mounts.

Thanks for that, Matt. I might go the boat roller route instead of pucks.


My only ideas/additions to this design is to prime and window weld the bolt so that it transfers forces better to the roller or the pucks. Even if we think its a tight fit, there is still space between the bolt and pucks or roller and I think some 3M goo should bring everything a little closer together. I would also put a bushing on the other side of the mount before the 1/2" washer.

I am for sure putting bushings on all metal contact spots above and below the subframe and mount bracket. Probably going to need a 9" bolt to make this happen.

Make sure to get a grade ten or at least eight bolt.

Last weekend I attempted to swap out my front mount. Jack/supported the trans, removed the bracket and thought the bolt would drop out from the mount.

Abaddon confirmed what I was afraid of, the mount is 1 piece. I needed another set of hands to hold the nut on top of the mount while I took off the bottom

I put the stocker back together and will try again once the temps go back up a lil and I have some helping hands!

Here's what my mount looks like. 4" boat roller with window weld filled end caps as bushings. One below the cradle and the other on top of the bracket.
