on the subject of springs: im very happy with the handling and the comfort of the 2015 gt pp springs and anti-roll bars. i can't say much about the dampers since i don't know how worn mine are, but they seem just fine. my car has rolled about 39k miles.

Im getting a fresh set of Koni Special Active with 2024-25 date code. First 2019 set had defects but were great for first 2-3 weeks.

First Mustang and I didnt realize I'd end up liking it a lot. 2016 GT Premium spec with the 6 speed auto and 3.15 rear end.

I know some are already shaking their heads at the last part lol but it's a good starting point for what I want for this car - a long distance cruiser that I can have some fun in the mountains with.

Now I've seen all the memes and vids so I was approaching fun driving in the twisties gradually. I was pleasantly surprised with it's dynamics in places like on/off ramps a bit faster than normal and I thought stock would be fine.

But when I started giving it some beans on one of my favorite turns, I felt the rear skip a beat.

For perspective I've taken (slid lol) this curve whenever it's clear with a variety of cars like turbocharged Subarus and RWD NA and FI AMG's and I've never felt that.

Basically the only thing I want to eliminate is that. Not really looking to increase ultimate grip or adding a more sporty feel, just that the rear not let go at a bit of spirited driving.

So I guess this is a variation of the age old question here of fixing the rear IRS with the least NVH.

I just noticed that JasonStang is selling a brand new Steeda IRS alignment kit for $50. If I were you, I'd snap that up and start there.

definitely.

Mine had constant whine. I don't mind that on a track car but not when driving on the freeway. I ended up filling the voids with 3M urethane.

did you have the braces installed with the diff inserts? i can imagine the braces would transmit the whine into the chassis really well. i will still have complete isolation through a flexible bushing.

Whine is there without the braces

dang. i think i remember some people saying things got better after they broke in over a few weeks. i guess we'll see.

I drove the GT today, my route was clear enough that I was able to step on it a bit.

I took a few turns quickly but smoothly, just 6/10ths or so, and all was good. I can see what our other members like S550HP were saying that in their opinion it takes a bit to reach the limit to make the subframe flex cause trouble. But roads were good weather was dry and roads warm.

Right now I think quick but smooth and the car wont bite. But throw in a bump mid turn with a bit less finesse on the throttle, or a more aggressive driving style, and it may reach limits earlier.

Driving it GT style is fine overall so far. One of these days on the right roads I'll experiment and wring its neck a bit and see how it acts. I'll be careful though, I've seen enough youtube mustang meme vids to see what can happen lol.
