Update - I couldn’t wait so I ended up having the pitch mount installed while getting an oil change. With the 60a bushing, there is an increase in NVH below 1400rpms but it’s not jarring. Holding the brakes down does seem to minimize it. From the quick 20min drive home, I can confirm the shifter feel is significantly improved and overall the car feels a bit stiffer. Not sure if that’s placebo or what, but I personally wasn’t expecting the car to feel this different (in a good way). I’ll report back after I’ve been able to drive the car more over the next few weeks.
 
Installed my Delta X this weekend along with my first oil change.
Just used ramps and it was easy. Takes longer to remove the lower cover than to replace the pitch mount.
At idle, NVH has increased but once moving it is fine and remember we have a 500 mile break-in period.
Shifting is smooth and in my humble opinion, the Delta X pitch mount was a great investment.

@Corolla Max thanks for sharing. Pro tip if you ever need to swap out bushings in the future it’s easily done without removing the front most under-panel which will save a little time. I just wanted to make the instructions newbie proof. Also depending driving habits and climate the break in could take up to 1k miles from some feed back I have received. If the NVH hasn’t settled into your likening by that point I would suggest going for a lower duro.

**Update for those who are currently waiting on the next batch.

I will pick up the parts from anodizing tomorrow and start the laser etching. Bushing manufacturing is being finalized so I will be accepting orders in the next week so.
 
I had the Delta X Motorsport pitch mount (60a) for over a week now, but wanted to install along with doing an oil change. Two birds, one stone.

For the install, it wasn't too bad. Can be done in within an hour. Having a Milwaukee impact wrench makes the removal, a breeze. My worries going in was, the transmission moving once the factory pitch mount was removed and lucky it didn't move. The second was, torquing to a high setting. Started at 125ft-lbs and worked up to the 148ft-lbs with the subframe through bolt. One more thing on the install, awesome instructions.

You talk about nvh, you notice it right off the bat on the initial cold start up. I could only imagine on the 70a or 80a bushings. Lol. Like others have stated, the nvh goes away once you start driving, but do feel a lot on the initial takeoff from a stop. I'm going to be honest, this is my first aftermarket pitch mount, but I didn't feel a night and day difference with shifting. Maybe there's a break in for that as well as the nvh!?

For break in, I'm at 2981mi and live in Florida. I'll update this post after 500mi.

Thanks for the initial review. The NVH in the 60A will surly dissipate with a break in. Shifting improvements are mostly felt in the higher RPM range when the engine would normally lurch pretty hard during off throttle inputs while upshifting and down shifting. Where the benefits are noticeable are more so in the shifting engagements as opposed to the actual shifter feel. You should feel a much better "connectedness" and it will increase with going up in duro at the expense of more NVH. The pitch mount will also come into play to help with torque steer and wheel hop that may be introduced once owners start to add more power.

I do plan to release some shifter bushings and linkages in the future to improve on the shifter feel.
side note: there are a few companies that have some stuff out now with decent reviews

BTW great pictures. I think i actually forgot to post the picture's I had of parts weighing so thanks for that. It was in my design plans to ensure not to add any weight over factory!

By no means, was I trying to hate on your pitch mount. My expectations of the pm was different than what it's supposed to accomplished. Driving to and from work yesterday/today, the GR felt more rigid plus a better pedal feel driving on the highway (If that makes sense) I could only imagine with some more break in along with more bracing, how this car will feel. Thank you again for the GRC support.

@Bryota_GR No offense taken. I know it wasn't a jab and that it's just the pitch mount did quite live up to your expectations and I apologize for that if you were misled. I just wanted to add a little info for anyone in the future who maybe interested so they are not misled. Also not targeted to you but rest assured for anyone if they are not happy with the pitch mount for any reason it can always be returned for a full refund.

For anyone else who is interested I have opened up pre-ordering for the batch of 50 I have now. The kits are ready to go minus the bushings. I have received tracking for the bushing shipment today so the kits could be shipped out to everyone as early as next week. (depending on how well the post is working at this time) Price is still the same at $225 shipped.

On another note. I have been called to duty via Uncle Sam. I will be out of country for 90 days starting in January. So with that being said this will be my last batch available until April 2024. I will have someone here stateside fulfilling all orders. Bushing sets will also be available until sold out (but I think I have enough to cover until I return). I also have a fresh batch of pedal spacers. Unfortunately all other part projects will be put on hold until I return including website but that will be my main priority once I return. Again I do want to thank everyone for the support so far. I am considering buying a shop this year and going all in on the GRC parts development and not just doing it as a hobby, we shall see!

Here are a few pics for amusement:

You don't have to apologize. I don't feel misled. It's a great piece and the more I drive, the better the GR feels. Can't wait to see future projects from you after your return from deployment. Thanks again for your service. God bless and safe travels.
 
I swapped to the 70a last week and the vibration isn’t that bad to me, definitely an increase though. The 60a continued to soften up upwards of 1000 miles, especially after some spirited driving on the dragon. It could get better still. I’ll post an update once I have the 70a well broken in. A lot of this is probably just preference though.
quick update on this. After dailying with the 70a bushing for roughly 1000 miles I have switched back to the 60a bushing. It is hard to beat the smooth drive-ability of the 60a with the added stiffness compared to OE mount. The added 70a vibrations just aren't necessary to me and will go straight to the 80a for track use then switch back to the 60a for comfortable daily driving. I sometimes have passengers and this also sways me to use the 60a. Overall completely satisfied and will use this forever. While I am spoiled and have access to a lift, I love that I can swap out the bushing in 5 minutes whenever I feel like switching.
 
I sadly have not installed my 60a yet. I had meant to install it during my 10k but I completely forgot. I'll get to it eventually. Maybe Saturday before I leave for Toyota Fest.
