Ground clearance?

[tight fart]

I used to use my car mainly on the track and had the suspension set up for that, now I’m only using it on the road.
Problem I have is I only have 50mm of clearance under the bell housing.
I can’t raise the engine so I’m thinking just adjust the spring height.
Am I going to need the tracking adjusted if I lift the car a cm?

I cant help with an answer but im curious if your car has the lowered floor? As ground clearance is something i am worrying about when purchasing (massive speed bumps here in France)
