It took me a bit of time to remember but I finally remembered how I 'lowered' my HW Ferrari 250 SWB
The truth is it sits lower, not because of any suspension 'tweaks' but because I changed the tires.
I was looking for higher side profile tires for my XKE's. I only found one set in my spare tire collection so I decided to try a switch with one of my late 50's early 60's cars.
Not an ideal solution, but until I can find a better one I think both models benefited.
And yes, I did 'lower' the XKE's
