I went cheap with the lowering springs honestly and bought the Godspeed project ones, the ride and handling is definitely better then stock but I’ve noticed it sways a little more at times, almost feels like I’m gliding slightly left or right depending on the road I’m on. Alignment might be off but it doesn’t pull left or right like it would. Think of what it would be like driving an air hockey puck but with a little bit of traction
You might have a problem with the front Toe setting. If you have any toe out at all, it can make it wander a bit at speed.
A good goal for a street alignment is 0 Toe front and rear with - 1.0 degrees negative camber front and rear. You will need to buy camber bolts for the front lower strut to knuckle, these cam bolts allow easy camber change at the alignment shop, and cost $15-$20.
You might have a little more understeer too, with GodSpeed having about .5 kg higher front rates vs .3kg higher rear rates.
Did the GodSpeed come with any new bump stops, or instructions for trimming the stock bump stops?
Or did the new dampers come with new bump stops, and you should have trimmed them to match the GodSpeed bumps or the height they recommended trimming to, since GodSpeed would know the new ride height and travel on their springs.
Basically, taller front bump stops can also contribute to rougher ride and more understeer. While taller rear bump stops and trimming the front can reduce understeer, Too tall in the rear, with a lower ride height can also cause a rough ride from bottoming the bump stops
