if you changed the coil overs yourself, you can do this!

That spacer goes between the transmission mount and the frame of the car correct?

Sorry for all the extra questions, the spacer just came in today. Once I get the car on jack stands, where is the rear transmission mount located? What is a good spot on the transmission to place the floor jack? Do I need a flat plate to jack up the transmission to fit the spacer or will a normal floor jack not damage the bottom of the transmission? Again sorry for all the questions, I just don't wanna mess up my transmission

Look for a triangle of three bolts from under the engine cradle, 15 mm hex head bolts

place a 2x4 under the transmission, do not attempt to lift the transmission more then an 1”




From the top passenger side you can see the rear transmission mount

From the top driver’s side , there it is

Here’s a photo showing the triangle with the cradle out of the car for clarity, you don’t have to remove the cradle to install the spacer

Here’s more



This is from the passenger side with the steering rack removed to see the rear transmission mount on the cradle bracket, there in that circle highlighted

And from the driver’s side, that’s where you install the spacer Note: you don’t have to remove the steering rack, I just found these photos in my library.

Update

The transmission mount spacer worked! Far easier to do than I expected. The only issue I ran into was I didn't have the leverage to properly torque the bolts down (I didn't have a big enough pipe to fit on my torque wrench, but I still got them tight enough). If I had a lift it would have been much easier but harbor freight jack stands did the trick.

As far as the rack spacers, I was not able to install them. I did not have the proper extentions to reach it (or maybe I'm just dumb and wasn't thinking hard enough). There hasn't been much of an issue with bump steer so I'm not too concerned about waiting a bit longer. I do still intend on installing them in the future but mabey I'll just have a garage install them and align it for me all at once, I definitly need an alignment. Thanks again Oldblue, your a life saver!
