it has nothing to do w/ shock travel or performance
These arent spacers for the top-hat for shock travel...theyre for the spring perch to raise ride height slightly
Borrowed from CivicLX H-T
See the rear koni's have 3 spring perches...fronts have only 2. You can raise the ride by changing where the perch is w/ a circlip and ring combo.
I am going to make taller rings to sit on the circlips to give me a slightly higher ride since I already use the highest (stock) perch and its too low...so .5" lift will work nicely.
(I dont want the full 1" in the rear)
