Cure for high speed nervousness?

OptionZero

You got an alignment BEFORE you installed shocks/springs that lowered the car?

You realize those parts affect your alignment?

If you have sport dampers. Are they oem? How do you adjust them?

I have Koni Yellows that are adjustable with stock springs. I can adjust how how stiff or how soft the front or rear can be similar to coilovers that adjust dampening but I can't raise or lower my ride height.

I know about Koni's. But the way you worded it sounded kind of confusing. You said the way you have the dampers adjusted, then said you have the sport dampers. Meaning you have the stock sport dampers.

since you changed from oem to Koni's after you had an alignment. I would get it aligned again. The Koni's will lower the front by at least a 1/4". The lower spring perch is lower on the Koni's. Also the toe setting is most likely off. If the setting is zero to toe out. The car becomes less stable.

Sorry for the wording, they just call them Koni sport dampers in the video I was watching lol. I did try jamming on the brakes in a straight line today and that vibrating didn't show up but it still felt unstable when suddenly at a high speed and then going to a complete stop. It felt uneasy like the tires were just about ready to lose grip. So I think you may be right that it's the alignment, the shop that installed them said I won't need an alignment. I think he was full a crap.

After an alignment and slightly softening up the front dampeners, that high speed skittishness went away. My Alignment when I went to the shop wasn't off that much but I tried driving and doing the same thing afterwards and it's definitely less nervous now. I was thinking it was a combo of things. Maybe the front dampers were too stiff up front and the alignment being a tiny bit off combined with me slamming on the brakes (all the weight going up front) then asking those same tires that are already at their breaking point to switch lanes quickly caused this?

Either way it feels a lot better. Learned my lesson, will be saving up for the Greddy KW Coilovers or the Bilstein B16 PSS9/10 if I'm impatient or wait to get the KW V3's.
