Anyone measure bump & droop when installing coilovers? Roll Center?

Here are some pics of my bump(full compression, no springs) and droop (full decompression).

Rear full droop:


Rear full bump:


Rear Ride height:





Front full droop:


Front full bump:


Front Ride height:



Measurements: (from the top of the center cap to the center-most part of the fender)
Rear:

Fully Compressed (no spring): 317.5 mm

Full droop: 444.5 mm

Ride height (car on ground with spring): 352.425mm



Front:

Fully Compressed (no spring): 311.15 mm

Full Droop: 444.5 mm

Ride Height: 342.9mm

I may raise the front a bit, looks like I'll need a swift spring to properly preload the fronts, If I go any higher, the springs become loose. Only way to tell is to do a corner balance which will hopefully happen after I get my half-cage done.

When you did this. Did you watch to see how much the camber changes during full movement?

Would be very cool to know, at least as a reference. Would also love to know the changes in toe.

One can only dream. Watching Forza replay with live camber values overlay is fun, but not sure how realistic it is lol.

Unfortunately no, I haven’t aligned the car yet after installing my
SPL FUCA’s. So alignment is all outta whack. I do need to buy some mobile alignment tools to measure this kinda stuff.

Just moving the tire up and down, and eyeballing it.
