Hey everyone, I have a 2013 FR-S that I bought brand new way back in 2012. I have done quite a bit of modifications to it over the last 4 years and have been able to quickly diagnose and fix any problems I have experienced along the way. I haven't driven my car a whole lot this year but the times I have driven it, I notice that the steering doesn't feel like it used to. We all know how the car feels when giving steering input. My problem is that now, the car feels almost unpredictable when giving input (I drive backroads frequently and reach speeds of 80+ in corners). It's almost "laggy" if I can describe it that way.
So, when I am entering a corner and start to turn, it's like I can physically feel all the parts in the car turning, but then the actual car itself follows afterwards, instead of immediately. When I swerve back and forth I feel the parts moving but the car sways behind that input, somewhat how older cars feel when you just turn the wheel back and forth while driving, but with more of a pull to it.
Also, when hitting higher highway speeds (75-80+) the car wants to wander around the lane slightly, and definitely is very noticeable at 120+. I have never been iffy about taking my car up to that speed, but now it just does not feel safe. I am certain
something is wrong with my car, but I just don't know what it could be.
I thought maybe it something in the suspension or tires at first. I checked all tire pressures and they are fine (EDIT: Tires are Hankook V12 Evo2's and have less than 3k miles on them). I am running BC type BR coilovers and I checked them out and they seem to be fine. Sway bar end-links were all tight.
Next thought is possibly alignment or something physically wrong with the steering system?
Any input on this would be much appreciated. Thanks!
