Got STi transmission and motor mounts installed. With the header removed, the install process was easy and enjoyable.

Had the wife crawl under the car to show her things and she says 'Dumbass, you should have waited until you got the header, now you have to remove it again.' And then it clicked.

While the mounts were bolted to the engine and transmission, but not the frame, installed the ACE 350 header, ceramic coated in and out. The install was a breeze, everything fits perfectly with plenty of clearance. Waiting for my Delicious tune now.

Love the car and all the mods. The STI mounts are great at firming up the driveline with little to no NVH increase.

Sweet build, it looks like we have a similar thought process (focus on handling before power and keep it NA). I'm looking forward to seeing how the ACE header works out for you, as that's the one I'm considering for some point in the future as well.

I saw you had an alignment result above, did you find a shop that does performance alignments? I'm still trying to figure out where I'm going to go here in South Texas. Only place I know of is Soulspeed in Austin, doesn't look like there's anything here in San Antonio.

I still have to upgrade the suspension, it just happened the headers came first. :) Soulspeed is good; I thought Rich was closer to or at Harris Hill but guess not. I have my alignments done at Mansel's in Bryan, it is an old school shop, they let me put weights in the driver seat to account for my weight, etc, can't beat that for $75 + tip.

Can Mansel's do corner balancing? If so, I may be road-tripping to Bryan/College Station when I do suspension replacement next year. Soulspeed closed in the Harris Hill location in 2012 and then reopened sometime afterwards in Austin proper. I have never been in there, but it seems to be the best regarded place to go according to folks I've asked around here, but it's quite a hike. I guess Mansel's would be quite a hike too. I wish San Antonio had a proper alignment shop.

Finished my Delicious tune. The car is pulling very smoothly and in a linear fashion throughout the entire rev range which makes me very very happy. Totally worth it. :)

So its a nice improvement from the stock 2017 tune? I have DT on the way as well!

It will not push your head into the headrest so to speak, not enough hp for that but you bury the gas pedal and have a nice, smooth, consistent pull from 3000 rpm to 7800 rpm. The torque dip is gone, gone, gone. :)

That's all I care about! For the street, this car is plenty fast at redline. No problems with the power up top as far as I'm concerned. Glad to hear it.

Installed the Essex harness bar and Schroth Rallye Cross harnesses.

The harness bar in the lowest position is a must to keep the harnesses parallel with the ground or at a slight angle. A 255 tire still clears but you cannot fold/unfold the rear back rest, you need to take out the two lower bolts behind the back rest to disengage it from the brackets and then the back rest just slips in under the bar.

Eye balled the location of the harness bar on the side panels (official name is "luggage compartment trim covers") and drilled a 2" hole in the panels, which I later expanded a bit to better match the actual bar location. Put a rubber trim from a Miata around the holes for a cleaner look.

It is possible to re-use the b-pillar covers ("center pillar garnish") but you have to trim them a bit and gut all the plastic ribs on the inside.

WOW that harness bar looks great! Where did you get the miata grommet? for those of us who would like to replicate this :D

Look for a "door sill pinch weld moulding" for Miatas or you can get a universal one, something like this.
