5ktq spring "damper" thickness

[Brian Devlin]

I'm refering to the rubber/plastic rings that sit on top of the
springs. Bentley says they come in three thickenss and each is marked
by a number of hash marks. Can these marks be seen on the car, or
would I have to take the struts apart? Are there thicknesses other
than the 19, 14 and 9mm listed in Bentley? If you're wondering, I am
thinking about a little bit of lowering for the car.
