Great review from William in CA:

Product Name: Steeda S550 Mustang Rear IRS Subframe Support Braces (2015-2019 Coupe)
Headline: great product
Location: CA
Review: I am a old SCCA road racer and love modifying my street cars to handle the best the can if and when I ever it to the track for a HPDE day. I have several Steeda handling products on my 2018 GT PP1 and love them all. I am not a tire burner and didnt really know if this would help the unbalance feel I seam to notice in the rear of the car, but thought I would give it a try. Adding this subframe support brace really brought everything together. I highly recommend this for the curves that you want to master.

Literally planning to install mine this weekend.

Just installed mine today. U can definitely feel a difference in the rear.

The RR stiffness and roll is greatly reduced to the point I'm afraid of installing my rear sway bar because of oversteer. This mod is definitely the equivalent of having an aftermarket RR sway bar.

The creak I have in the IRS bushing lockouts when pulling off is gone. So I'm very happy about that but still curious.

Rocking from on/off throttle is reduced.

Wheel hop with this and IRS bushing lockouts is no more than two oscillations for me.

Steeda appreciates your feed back. Steeda IRS sub-frame support braces are lightweight and extremely effective.
They are used on our record setting drag and road race cars!

I had mine installed on Wednesday. It makes a huge difference. I feel more confident in turns. The back end feels more planted, a very noticeable difference. I installed the vertical links a couple weeks ago. I really didn’t notice a difference there but the two together, I am very pleased.

I took a video today. Its pointless without a before but there is no subframe movement compared to what I've seen in other vids, just the diff. There is actually still wheel hop(from the diff), but it doesn't translate to the cabin so i did not notice it.

Best spot to watch is the corner of the subframe where the sway bar mounts.
