Has anyone Window-Welded the factory dogbone mount yet?

I did. Check the dates on the posts.

However, I now have a different Civic and am back to an unfilled mount that needs to be filled. Ha!

Same here! My EX-T's mount was window welded now but on my new Si I haven't had the chance to do it yet.

I did this, no noticeable NVH compared to stock, not sure how to test the extra stiffness though..

Are there different types and strengths of window weld or basically one type? I'd debating the hard race mount or just buying the TypeR one to window weld.

Just one Window Weld.

On a related note, I have a spared Window Welded Si mount that I’d be willing to sell or trade for an OEM mount + cash, if anyone is interested.

How much for the window welded SI mount straight up, no trade? PM me if you'd like.

What does the install entail? I'm somewhat mechanically inclined but do I have to prop the engine up at all or is it a simple quick swap?

Would sell mine for 75 shipped, and it’s 2 bolts for installation of course you have to take the skid plate off the bottom for access.

Does the window welded SI add any vibrations at any RPMs or idle?

I'd prefer to swap mine for cash + core so I will let @bahndrvr sell his if desired. The install is super easy, you'll need a 17mm and 19mm socket or wrench.

Having experience with several Window Welded mounts, I've only had one that had any noticeable vibration at idle. Even then, it was MUCH less severe than what you'd find with an aftermarket mount such as one from Boomba or Hasport. I've never had the pleasure of testing the Hardrace mount.

I've used this in the past for making my own poly motor mounts.

How did the welded mounts hold up? And issues after some time? Anyone run in winter?

Nice. I'm cleaned my factory SI mount today. And I've got everything I need to weld it up!

Thanks for the response!
