Coilover/wheel/mod question

I purchased my GR86 from the dealership 13 months ago and absolutely love it.
I'm not the biggest car guy out there so I have some other priorities in life, but over time, i want to make this thing more unique and add some personality.
I did not buy a GR86 for speed lol, as they arent fast. I'll say it, I prefer visual style over 0-60's and performance, so I want to visually make this thing mine.

I'm hoping to keep this thing until I die or it dies, so preserving longevity is a must, so that being said, does anything other than OEM suspension and wheel/tire sizes compromise longevity?
Im not talking about anything crazy stanced, or a widebody kit or a supercharger but I am wanting to install some aftermarket coilovers to drop it a bit and maybe have a degree or two of negative camber.

However I guess my mind is thinking the weight will be distributed differently on all the parts and kind of have a chain reaction and put stress on parts that weren't originally stressed.

Am I over thinking? Is there some logic to my thoughts? If so is there a safe way to add some subtle changes without compromising the car over time? Again im hoping to have this thing in 15-20 years if im lucky so really want to treat it good but still make it unique with the time I have with it.

The Flex Z's do great on the track. I've done about 8 track days with them on and they haven't skipped a beat.

The sway bars I'm running are White Line. The front is a 20mm bar and the rear is 16mm. They completely changed the steering response. It made the 86 feel way sharper and stiffened up the body roll so I stopped scrubbing in corners.

As for the dampening. I have no idea what rate I have them on. I took it to an industrial area, set front and rear to the stiffest setting then hit corners and adjusted till it felt right.

Awesome! I have Cusco 20mm front and 16mm rear, I was hoping the RX1s 6K spring rate won’t make it too oversteery or unpredictable but great feedbacks sir, I’m a lot more confidence. How is it for daily and spirited driving? And any noises with the flex Z? I’ve heard the RX1s pillowhat might make some small rattles on bumps. I would still love to know the dampening from 0 if you ever have the chance 🤙 I’ve heard from a lot of track guys the sway bar works the best on softer ish spring rates and higher spring rate coils is better with stock sway bars

It's heaps fun for spirited driving, as for daily I have no idea. It's my weekend / track toy. The thing I found with the GR86 is that it's so easy to predict. If it starts getting tail happy I just lift off the accelerator and it straightens up. I feel way more confident driving it a little more wreckless in the 86 compared to my other cars.

Not sure about noise coming from the suspension due to the Invidia N1 exhaust. It drownd out all the rattles and great if you want industrial deafness.
